Description

[0001] Multi-part mattress

[0002] Reference to related applications

[0003] This application claims priority from German Utility Model No. 20 2023 102448, filed on May 5, 2023, which is incorporated in its entirety by reference into the present document.

[0004] Technical area

[0005] The invention generally relates to a mattress, in particular a combination or reversible mattress with several stacked mattress elements, wherein the mattress has two outer surfaces designed as lying surfaces. In particular, the mattress according to the invention can be advantageously used with box spring beds or low beds, but is not limited thereto.

[0006] Background of the invention

[0007] Mattresses have long served as a support and / or sleeping surface for a user and are constantly being developed, particularly with regard to comfort and ergonomics. Mattresses typically have a maximum thickness of around 18 cm.

[0008] To improve sleeping comfort, mattresses can also be designed, for example, with adjacent zones, areas, support areas, and / or regions of varying hardness, compressibility, compressive hardness, and / or elasticity along the length of the mattress. In this way, the depth of penetration of the user lying on the mattress can be adapted to the user's body shape. This can also ensure that the user lies on the mattress with the spine as straight as possible when lying on their side. The same applies when lying on their back, where the spine can be supported so that it assumes its natural S-shape.By providing several support areas or areas of different compression hardness, hereinafter also referred to as ergonomic zones, the weight distribution of the user on one of the lying surfaces of the mattress can be advantageously taken into account and thus an ergonomic posture of the user can be ensured, for example in several sleeping positions and / or sleeping postures of the user.

[0009] Such ergonomic adjustment of mattresses currently only exists for mattresses with a maximum thickness of 18 cm - 20 cm, e.g., mattresses for box spring beds or very low beds or bed frames, as is often the case in southern European regions such as Spain. This may be due, among other things, to the fact that with greater thicknesses, the ergonomic zones cannot be sufficiently developed, which can lead to a deterioration in the sleeping comfort and ergonomics.

[0010] Summary of the invention

[0011] Embodiments of the invention advantageously make it possible to provide a user with an improved mattress, in particular a reversible mattress, which is characterized in particular by increased sleeping comfort. In particular, the mattress according to the invention can also be used on low beds or bed frames, as well as on box spring beds, while providing improved sleeping comfort.

[0012] This is made possible in particular by the subject matter of the independent claim. Advantageous embodiments and further developments are specified in the dependent claims and the following description.

[0013] One aspect of the present disclosure relates to a mattress, combination mattress, and / or reversible mattress. In particular, the mattress can be usable on both sides for a user and / or provide two lying surfaces of different compression hardness. The mattress has at least a first mattress element with a first contact surface and an oppositely arranged first outer surface, which is designed as a first lying surface for a user. Furthermore, the mattress has at least a second mattress element with a second contact surface and an oppositely arranged second outer surface, which is designed as a second lying surface for a user. The first mattress element and the second mattress element are stacked on top of one another such that the first contact surface of the first mattress element and the second contact surface of the second mattress element are at least partially in contact with one another.The first and second mattress elements can, for example, be positioned one above the other and / or one above the other. In particular, the first and second mattress elements can be positioned one above the other without further fastening, or the first and second mattress elements can be connected to one another via the first and second contact surfaces, for example, knitted, glued, fastened by a zipper, or fastened in some other way. The mattress has at least one head support area for supporting a head, at least one neck support area for supporting a neck, at least one shoulder support area for supporting shoulders, at least one lordosis support area for supporting at least part of a spine, and at least one pelvic support area for supporting a pelvis of the user.The first mattress element has a profile on the first outer surface and / or the second mattress element has a profile on at least one of the second outer surface and the second contact surface, such that the first mattress element and the second mattress element (and / or the first and second outer surfaces) have different compression hardnesses and / or differ in their degree of hardness. The thickness of the mattress is at least 24 cm. The thickness of the mattress can be measured transversely to a longitudinal axis of the mattress, transversely to a transverse axis of the mattress, and / or parallel to a vertical axis of the mattress. Alternatively, the mattress can have a thickness of at least 22 cm.The profile arranged on the second outer surface of the second mattress element has a plurality of, in particular three, recesses in the at least one pelvic support region, wherein the plurality of recesses have a triangular cross-section, and wherein the plurality of recesses differ at least partially in the cross-sectional area.

[0014] Here and below, the profile formed "on the" first and / or second outer surface can mean that the respective profile is formed in the region of, adjacent to and / or close to the first and / or second outer surface. The first and / or second outer surface can be substantially smooth and / or flat. For example, the profile formed on the first outer surface can have one or more recesses with any cross-section and / or any cross-sectional geometry, which each border the first outer surface and / or are connected to the first outer surface, for example via an incision.Alternatively or additionally, the profile formed on the second outer surface may have one or more recesses with any cross-section and / or any cross-sectional geometry, which each adjoin the second outer surface and / or are connected to the second outer surface, for example via an incision.

[0015] For example, in the areas of the mattress, i.e. head support area, neck support area, shoulder support area, lumbar support area and pelvic support area, at least partially different profiles, for example with different recesses and / or depressions, can be introduced into the first outer surface and / or the second outer surface, so that the compression hardness and / or the support properties of the respective area can be adapted and / or changed, for example in comparison to mattress elements without a profile. This allows a user to sink to different depths into the mattress and / or into the respective outer surface (or lying surface) on which the user is lying in the respective area. The different areas can also take into account the distribution of the user's weight over at least part of the first and / or second lying surface.For example, the different compression hardnesses of the areas can take into account the fact that the user's head is lighter than the pelvis, so that the head support area can have a lower compression hardness than the pelvic support area. The different compression hardnesses in the various areas can also ensure that the user's spine or back is straight, for example when the user is lying on their side, or has the typical S-shape, for example when the user is lying on their back. Furthermore, the different contact surfaces of different parts of the user's body can be advantageously taken into account, since the user's shoulders, for example, usually have a larger contact surface than the user's head.

[0016] The profile on the first outer surface and / or at least one of the second outer surface and the second contact surface can, for example, have one or more grooves, beads, grooves, incisions, cutouts, transverse grooves, channels, notches and / or recesses.

[0017] In particular, the profile of the first outer surface, the second outer surface, the first contact surface, and / or the second contact surface can have a plurality of transverse grooves, which can extend parallel to one another and / or parallel to a transverse axis of the mattress. The transverse grooves on one side or surface of the mattress can be spaced apart from one another in the longitudinal direction of the mattress, so that at least part of the respective surface or side of the mattress can be provided with a profile.

[0018] The aforementioned areas, i.e., the head support area, the neck support area, the shoulder support area, the lumbar support area, and the pelvic support area, can refer to different lying zones, zones, support areas, regions, and / or lying areas of the mattress. For example, degrees of firmness can have a variety of firmness classes. The firmness classes can include, but are not limited to, very soft, soft to medium-hard, medium-hard to hard, hard, and very hard. Alternatively or additionally, the firmness level can be specified in H1 to H5.

[0019] By providing the first mattress element and the second mattress element, each with different degrees of firmness, a combination reversible mattress can be created. The user can thus select the appropriate degree of firmness by selecting the first or second sleeping surface. To select the degree of firmness, the mattress can be rotated approximately 180 degrees around a longitudinal axis and / or a transverse axis of the mattress. Furthermore, by providing a mattress with a thickness of at least 24 cm, a thicker mattress than the usual 18 cm mattress can be provided for a user, whereby this mattress also offers increased sleeping comfort.

[0020] According to one embodiment, the first mattress element on the first outer surface and the second mattress element on the second outer surface have at least partially different profiles from each other.

[0021] By forming a first profile on the first outer surface of the first mattress element and a second profile on the second outer surface of the second mattress element, which at least partially differs from the first profile, a lying surface with a different degree of firmness can be formed on each outer surface of the mattress element or mattress, and / or the degrees of firmness can be coordinated. This makes it possible to provide an improved combination reversible mattress, for example, with a hard and a softer side or outer surface. This allows the individual needs and different anatomies of different users to be taken into account, and each user can choose the side or outer surface of the mattress that best suits their needs.According to one embodiment, the thickness of the mattress is determined solely by the thickness of the first mattress element and the second mattress element, and / or the thickness of the mattress is determined by the sum of the thicknesses of the first mattress element and the second mattress element. The thickness of the mattress elements and / or the mattress can be measured transversely to a longitudinal axis of the mattress, transversely to a transverse axis of the mattress, and / or parallel to a vertical axis of the mattress. Alternatively or additionally, the mattress has exactly two mattress elements. Optionally, however, the mattress can also have more than two mattress elements.

[0022] According to one embodiment, the thicknesses of the first mattress element and the second mattress element are identical. Alternatively, the thicknesses of the two mattress elements can differ. In particular, the thickness of one mattress element can be greater than the thickness of the other mattress element. The compression hardness can also be changed and / or adjusted via the thickness of the respective mattress element.

[0023] According to one embodiment, the first and second mattress elements comprise at least partially different materials from one another. In particular, the material of one mattress element can be more elastic and / or more deformable than the material of the other mattress element. Alternatively, the materials of the first and second mattress elements can be identical but differ in one or more material properties, in particular in their elasticity and / or deformability. For example, both mattress elements can comprise a foam material, wherein a pore size of the first mattress element can differ from a pore size of the second mattress element, so that both mattress elements can be deformable to different degrees.This may mean, for example, that a defined mass sinks deeper into the first outer surface than into the second outer surface if the first mattress element is more deformable and / or has a lower compression hardness than the second mattress element.

[0024] According to one embodiment, the thickness of the mattress is between 24 cm and 30 cm, in particular between 25 cm and 29 cm, for example around 27 cm. Such mattress thicknesses can be advantageous, particularly when used on box spring beds and / or low beds, offering improved sleeping comfort and / or making getting in and out of bed easier. It is also possible to dispense with a bed frame and / or slatted frame altogether. By providing a mattress with a thickness between 24 cm and 30 cm, in particular between 25 cm and 29 cm, for example around 27 cm, the mattress can be used, for example, for a box spring bed but also for free lying, i.e. not lying in any bed frame. Consequently, such a mattress can also lie on a surface, such as the floor, and still offer improved sleeping comfort.The thickness of the mattress can also make it easier for a user to get up from the mattress surface.

[0025] According to one embodiment, the second contact surface of the second mattress element has a serrated and / or tooth-shaped profile at least in the at least one head support area, the at least one neck support area, the at least one shoulder support area, and / or in the at least one lumbar support area. Alternatively or additionally, the second contact surface can also have a serrated and / or tooth-shaped profile at least in a partial area.

[0026] In the context of the present disclosure, the serrated and / or tooth-shaped profile may refer to a profile (and / or a profiling and / or a structure) which has one or more depressions and / or transverse grooves introduced into the second contact surface, so that the second mattress element, in a longitudinal section through the mattress parallel to a longitudinal axis of the mattress, has a tooth-shaped and / or serrated geometry and / or contour, for example at the second contact surface, at least in a partial area.

[0027] By forming the profiles on the first outer surface and the second outer surface and by forming the jagged and / or tooth-shaped profile on the second contact surface of the second mattress element, the support properties and / or compression hardness of different areas of the mattress, in particular the head support area, the neck support area, the shoulder support area and / or the lordosis support area, can advantageously be designed to be different from one another or from the pelvic support area. Such a profile can also be introduced into the second contact surface cost-effectively, reliably, quickly and precisely. In addition, the compression hardness and / or support properties of individual areas of the mattress can be adjusted efficiently and effectively using such a profile. Alternatively or additionally, different compression hardnesses can be achieved by using different materials, such as materials of different hardness orsoft material, such as mattress foam and / or polyurethane foam.

[0028] According to one embodiment, the serrated and / or toothed profile has at least one recess (and / or transverse groove) with a rectangular cross-section. Optionally, several transverse grooves with a rectangular cross-section can be provided, which can extend substantially parallel to one another and parallel to a transverse axis of the mattress. This allows the compression hardness and / or support properties to be efficiently and effectively adjusted in the areas of the mattress where the serrated and / or toothed profile is present. Different transverse grooves can be spaced apart from one another in the longitudinal direction of the mattress.

[0029] The cross-section of the depression can relate to the at least one depression. In other words, the cross-section can denote a cross-section through the depression. A cross-section through a depression can, for example, represent a longitudinal section through the mattress, in particular if the depression runs essentially parallel to a transverse axis of the mattress or extends parallel to a transverse axis of the mattress. In other words, the cross-section of the recess can run parallel to a longitudinal axis and / or be defined by a longitudinal section through the mattress. The depression with a rectangular cross-section can also be referred to below as a rectangular depression.

[0030] According to one embodiment, the at least one recess, in particular a rectangular recess, of the serrated and / or tooth-shaped profile each extends across the entire width of the mattress, substantially parallel to a transverse axis of the mattress. In particular, multiple recesses can be provided, each extending across the entire width parallel to the transverse axis of the mattress and / or parallel to one another. This allows the compression strength and / or support properties in the areas of the mattress where the serrated and / or tooth-shaped profile is present to be efficiently and effectively adjusted.

[0031] The recesses can be created, for example, with a cutting tool in the second contact surface, the first contact surface, the first outer surface, and / or the second outer surface. The recesses can extend completely through the mattress from a first transverse side of the mattress to a second, opposite transverse side of the mattress. The depth of the recesses can be measured in a vertical direction and / or parallel to a vertical axis of the mattress, starting from the respective side or surface of the mattress.

[0032] According to one embodiment, the jagged and / or toothed profile is formed exclusively on the second contact surface of the second mattress element and / or the first contact surface of the first mattress element is profileless, smooth and / or flat. Profileless means that no profile is formed on the first contact surface of the first mattress element and / or no depressions are formed on the first contact surface. Smooth here means that the first contact surface of the first mattress element has no structures, elevations and / or recesses. This advantageously makes it possible to provide different degrees of hardness for the first lying surface and the second lying surface. In addition, the formation of these areas of the jagged and / or toothed profile can advantageously provide different support properties and / or compression hardness.

[0033] According to one embodiment, the recesses of the serrated and / or toothed profile are equidistantly spaced in the longitudinal direction of the mattress, in particular parallel to the longitudinal axis. In other words, directly adjacent recesses of the serrated and / or toothed profile are spaced an identical distance apart. This allows the compression hardness and / or support properties in the areas of the mattress where the serrated and / or toothed profile is present to be efficiently and effectively adjusted.

[0034] According to one embodiment, the distance between the recesses of the serrated and / or tooth-shaped profile in the longitudinal direction of the mattress is equal to a length or width or dimension of the respective recess in the longitudinal direction of the mattress. In other words, two adjacent recesses are arranged such that the adjacent recesses are spaced apart by a distance corresponding to the respective dimension of the recesses in the longitudinal direction of the mattress.

[0035] According to one embodiment, the recesses of the serrated and / or tooth-shaped profile have identical depths. Alternatively or additionally, the recesses of the serrated and / or tooth-shaped profile are introduced into the second contact surface of the second mattress element to the same depth. This can, in particular, simplify the manufacture of the mattress and enable a targeted formation of the ergonomic zones. According to one embodiment, the serrated and / or tooth-shaped profile is symmetrical, in particular mirror-symmetrical, relative to a central transverse axis and / or a central transverse plane of the mattress.

[0036] According to one embodiment, the first outer surface of the first mattress element and the second outer surface of the second mattress element each have a profile, and the profile formed on the first outer surface and the profile formed on the second outer surface are each formed symmetrically, in particular mirror-symmetrically, relative to a central transverse axis of the mattress.

[0037] The symmetrical design of the serrated and / or toothed profile simplifies mattress production and reduces manufacturing costs, as the serrated and / or toothed profiles of the mattress can be machined with the same tool. Handling the mattress is also simplified, as the user only needs to select the most suitable sleeping surface.

[0038] According to one embodiment, the profile formed on the first outer surface of the first mattress element and / or the profile formed on the second outer surface of the second mattress element has at least one recess with a round, rounded, triangular, roundish, circular, elliptical, oval, T-shaped, and / or drop-shaped cross-section. The recess can here and hereinafter refer to a cavity and / or a hollow space formed at least partially in the first and / or second mattress element. The recesses of the respective profiles, in particular the profiles formed on the first and second outer surfaces, can in principle have any desired depths, arrangements, cross-sectional geometries, cross-sectional areas, and / or cross-sections, such as T-shaped, triangular, square, rectangular, cuboid, polygonal, round, oval, and / or elliptical cross-sections (or cross-sectional geometries).

[0039] According to one embodiment, at least one recess in the profile formed on the first outer surface of the first mattress element extends across the entire width of the mattress, approximately in the transverse direction of the mattress, and is spaced from the first outer surface of the first mattress element in a vertical direction of the mattress (and / or parallel to a vertical axis), such that the at least one recess is formed in an internal volume of the first mattress element. The at least one recess is opened in the direction of the first outer surface via an incision extending through the mattress parallel to the at least one recess in the transverse direction of the mattress. The recess can be connected, as it were, to the first outer surface via the incision. A width of the incision measured parallel to the longitudinal axis can be smaller than a width (and / or a diameter) of the recess measured parallel to the longitudinal axis.By configuring the profile formed on the first outer surface in this way, the first outer surface can be designed to be substantially flat and / or smooth, since the recess can be at least partially covered by a layer of the first outer surface. Thus, the recess may not be noticeable to the user, and lying comfort can be increased.

[0040] According to one embodiment, at least one recess in the profile formed on the second outer surface of the second mattress element extends across the entire width of the mattress, approximately in the transverse direction of the mattress, and is spaced from the second outer surface of the second mattress element in a vertical direction of the mattress (and / or parallel to the vertical axis), such that the at least one recess is formed in an internal volume of the second mattress element. The at least one recess is opened in the direction of the second outer surface via an incision extending through the mattress parallel to the at least one recess in the transverse direction of the mattress. The recess can be connected, as it were, to the second outer surface via the incision. A width of the incision measured parallel to the longitudinal axis can be smaller than a width (and / or a diameter) of the recess measured parallel to the longitudinal axis.By designing the profile formed on the second outer surface in this way, the second outer surface can be designed to be substantially flat and / or smooth, since the recess can be at least partially covered by a layer of the second outer surface. Thus, the recess may not be noticeable to the user, and lying comfort can be increased.

[0041] According to one embodiment, the profile formed on the first outer surface of the first mattress element and the profile formed on the second outer surface of the second mattress element have a plurality of recesses. Furthermore, a diameter and / or a cross-sectional area of ​​at least some of the recesses differ from one another. This allows the support properties to be adapted in certain regions, for example in order to form the ergonomic zones. According to one embodiment, a depth and / or cross-sectional area of ​​at least some of the recesses of the profile formed on the first outer surface of the first mattress element differs from a depth and / or cross-sectional area of ​​at least some of the recesses of the profile formed on the second outer surface of the second mattress element. This allows different compression hardnesses of the two outer surfaces to be provided.

[0042] Alternatively or additionally, the depth of the recesses in the profile formed on the first outer surface of the first mattress element and the recesses in the profile formed on the second outer surface of the second mattress element depends on the cross-sectional area of ​​the recesses. The depth of a recess can refer to the orthogonal distance of the recess from the associated outer or contact surface into which the depression is made. In other words, the depth of the recesses differs depending on the cross-sectional area of ​​the recesses. For example, recesses with a larger cross-sectional area have a greater depth and / or a greater distance, measured in the vertical direction of the mattress, from the respective outer surface than recesses with a smaller cross-sectional area. Analogously, recesses with a smaller cross-sectional area have a shallower depth than recesses with a large cross-sectional area.Recesses with the same cross-sectional area can have an identical depth.

[0043] According to one embodiment, recesses (synonymously also referred to as depression or transverse groove) of the profile formed on the first outer surface of the first mattress element and the profile formed on the second outer surface of the second mattress element with an identical cross-sectional area have an identical depth.

[0044] According to one embodiment, a single recess of the profile formed on the first outer surface of the first mattress element and the profile formed on the second outer surface of the second mattress element is formed in the at least one headrest area. This allows for a suitable compression hardness and preferred ergonomics of the headrest area to be provided.

[0045] According to one embodiment, several, in particular five, recesses of the profile formed on the first outer surface of the first mattress element and the profile formed on the second outer surface of the second mattress element are formed in the at least one shoulder support area. This allows for a suitable compression hardness and preferred ergonomics of the shoulder support area to be provided.

[0046] According to one embodiment, the plurality of recesses of the profile formed on the first outer surface of the first mattress element are identically formed in the at least one shoulder support region.

[0047] According to one embodiment, the diameter and / or cross-sectional area of ​​the respective recesses of the profile formed on the second outer surface of the second mattress element decreases from an end of the at least one shoulder support area adjacent to the head area to an end of the at least one lumbar support area adjacent to the pelvic support area. The diameter and / or cross-sectional area of ​​the respective recesses can decrease gradually and / or continuously, but is not limited to this.

[0048] According to one embodiment, several, in particular three, recesses of the profile formed on the first outer surface of the first mattress element are formed in the at least one pelvic support area. This allows for a suitable compression hardness and preferred ergonomics of the pelvic support area to be provided.

[0049] According to one embodiment, the plurality of recesses of the profile formed on the first outer surface of the first mattress element in the at least one pelvic support region differ at least partially in their cross-sectional area. For example, the recesses may differ in their cross-section, depth, cross-sectional area, shape, geometry, direction of extension, and / or length.

[0050] According to one embodiment, at least one of the plurality of recesses of the profile formed on the first outer surface of the first mattress element in the at least one pelvic support region is identical to the single recess of the profile formed on the first outer surface of the first mattress element and the profile formed on the second outer surface of the second mattress element in the at least one head support region. In other words, at least one of the recesses formed in the pelvic region is identical to the single recess formed in the head support region. This allows for a suitable compression hardness and preferred ergonomics of the pelvic support region to be provided.

[0051] According to one embodiment, the mattress, the first mattress element and / or the second mattress element comprises a first half and a second half which are arranged one behind the other in the longitudinal direction and / or parallel to the longitudinal axis of the mattress, wherein the mattress, the first mattress element and / or the second mattress element each comprise a head support area, a neck support area, a shoulder support area, a lordosis support area and a pelvic support area in the first half and in the second half.

[0052] The support areas or areas can, for example, be formed in each of the first and second halves of the mattress as described below. A head support area extends from each end of the mattress in the direction of the central transverse axis. A neck support area is connected to each of the head support areas and extends further in the direction of the central transverse axis. A shoulder support area is connected to each of the neck support areas and extends further in the direction of the central transverse axis. A lumbar support area is connected to each shoulder support area and extends in the direction of the central transverse axis. A pelvic support area is connected to each lumbar support area and extends to the central transverse axis. The two pelvic support areas of the first half and the second half can form a common pelvic support area.

[0053] According to one embodiment, the first half and the second half are symmetrical to each other, in particular mirror-symmetrical to each other, relative to a central transverse axis and / or a central transverse plane of the mattress. The symmetrical design of the first half and the second half of the mattress simplifies the manufacture of the mattress and reduces manufacturing costs, since the two halves of the mattress can be machined with the same tool.

[0054] According to one embodiment, the first mattress element and / or the second mattress element is made of a foam, in particular a viscoelastic foam, a cold foam, a point-elastic foam, and / or a polyurethane foam. However, other materials, such as latex, natural latex, layered latex, gel foam, and / or polystyrene, are also possible. The individual mattress elements can be made of identical material, or at least some of the mattress elements can be made of different materials. The mattress elements can also have at least partially different colors, for example, to indicate to a user the respective degree of hardness of the lying surface. For example, a color of the first mattress element can differ from a color of the second mattress element. Furthermore, the first mattress element and / or the second mattress element can be made entirely or at least partially of a foam.

[0055] By using foam, unwanted drafts or air circulation through the mattress, the first mattress element, and / or the second mattress element can be reliably prevented. This can provide a warming sensation—that is, whether the mattress feels warm when used by a user—and improve sleeping comfort. In particular, insulation from the floor can be improved, for example, compared to innerspring mattresses.

[0056] According to one embodiment, the mattress further comprises a mattress cover which at least partially, in particular completely, encloses the first mattress element and the second mattress element, wherein the mattress cover has a first half and a second half which are at least partially connectable to one another with a closure, in particular a zipper, along at least part of an outer circumference of the mattress.

[0057] By providing a mattress cover on the mattress, damage and / or soiling of the mattress can be reliably prevented and the haptic properties or the user's lying comfort on the mattress can be improved.

[0058] The mattress cover can be opened via the fastener and completely removed, for example to wash the mattress cover. The mattress cover can be washed in particular at a washing temperature of up to approximately 75° Celsius, for example up to around 60° Celsius, which can advantageously simplify and / or enable comprehensive cleaning of the mattress cover. According to one embodiment, the first half of the mattress cover differs at least partially with regard to a fabric structure and / or fabric type of a cover material forming the mattress cover (or the first half of the mattress cover) from a cover material forming the second half of the mattress cover. Alternatively or additionally, the two halves of the mattress cover can have different colors.This can make it possible to indicate to the user which side and / or which of the first and second sleeping surfaces has a desired degree of firmness based on the different structure and / or color of each half of the mattress cover. In other words, the user can determine which sleeping surface has the desired degree of firmness based on the color and / or structure of the mattress cover (or the halves of the mattress cover). The color and / or structure of each half of the mattress cover can also be an indicator of the degree of firmness of the first and / or second sleeping surface covered by the respective half of the mattress cover. This allows the user to select the sleeping surface that is most suitable for them without, for example, removing the mattress cover. Overall, this can make handling of the mattress easier for the user.

[0059] The first half of the mattress cover can, in particular, at least partially enclose the first mattress element. The cover material of the first half of the mattress cover can be single-layered or multi-layered. For example, the cover material of the first half of the mattress cover can have an upper layer forming an outer material, which can serve as a support surface for the user. In addition, the cover material of the first half of the mattress cover can have a lower layer, which can be in at least partial contact with the first outer surface of the first mattress element. A layer of wadding, such as a layer of polyester wadding and / or climate wadding, can optionally be arranged between the upper layer and the lower layer. This can impart a pleasantly soft feel, voluminization, and / or a certain compressibility to the cover material.

[0060] The cover material of the first half of the mattress cover can further comprise honeycomb-like and / or honeycomb-shaped depressions, which can be arranged in a regular pattern in the cover material. The honeycomb-like depressions can advantageously fix the wadding layer between the upper layer and the lower layer. The cover material of the second half of the mattress cover can also be analogous and / or identical to the cover material of the first half of the mattress cover. Alternatively, however, the cover material of the second half of the mattress cover can differ from the cover material of the first half of the mattress cover, in particular with regard to construction, type of fabric, material composition, and / or fabric structure. For example, the cover material of the second half of the mattress cover can be at least partially siliconized and / or rubberized.For example, a latex layer can be applied to the outer surface of the cover fabric of the second half of the mattress cover. This can prevent the mattress from slipping on a supporting surface, such as a bed. This can be particularly advantageous for box spring beds, as the mattress is usually not held in place laterally by the edges of the bed and / or bed frame.

[0061] According to one embodiment, the cover material of the first half and / or the second half of the mattress cover is made at least partially, in particular completely, from a spacer knit, such as a three-dimensional spacer knit, wherein the mattress cover preferably has a honeycomb structure, a honeycomb structure and / or a honeycomb mesh structure with outwardly open recesses on its outer side. This can advantageously provide a breathable surface for the mattress, which can further improve lying comfort for the user. A mattress cover made from a spacer knit can also have an advantageous effect on the feel, particularly compared to a mattress cover made from a spacer knit, so that the mattress cover can feel soft and not scratchy.The honeycomb-like recesses can have any cross-section, in particular round, oval, elliptical, angular, and / or polygonal. The spacer fabric can be multi-layered, in particular two- or three-layered.

[0062] The recesses, such as those open to the outside, can be variable in terms of their geometry, for example, they can be round, square, oval, polygonal, elliptical, or any other shape with regard to their open cross-section. In the context of the present disclosure, the recesses formed at least on the outer side of the upper layer of the cover material are to be strictly distinguished from meshes from which the cover material, the lower layer, and / or the upper layer can be formed. Compared to the meshes, the recesses can be larger; for example, the recesses can have a cross-sectional area that can be many times larger (approximately 5 to 100 times or more) than an average cross-sectional area of ​​the meshes of the cover material.

[0063] The spacer knit can, for example, have a spacer structure with loops of interwoven monofilament or multifilament spacer threads. Due to the structural design of spacer knits, they can be more stretchable than conventional warp-knitted spacer fabrics, which can increase comfort for the mattress user, as the mattress cover with the spacer knit can be soft, elastic, and pleasant to the touch. Furthermore, the honeycomb structure on the outside of the mattress cover can increase air circulation and moisture wicking from the mattress.

[0064] The honeycomb-like, outwardly open recesses are not only advantageous in terms of air exchange and moisture removal as well as the compensation of temperature fluctuations in general, but can also enable increased elasticity, which offers the user a soft feel and also allows the mattress cover to adapt optimally to the user lying on it, without the user being affected by brittle spacer threads that are often noticeable in spacer knits.

[0065] The mattress cover can, for example, be produced on a large circular knitting machine using the so-called 3-way technology with a high throughput and therefore high cost-effectiveness.

[0066] The recesses of the mesh structure are preferably provided in a regular arrangement on the outside of the cover material and / or the mattress cover, although an irregular arrangement, for example forming a pattern, is also conceivable.

[0067] The honeycomb-like recesses open to the outside can be variable in terms of their geometry, for example round, elliptical and / or oval and / or even angular in terms of their open cross-section.

[0068] According to one embodiment, the cover fabric and / or the mattress cover made of 3D spacer knit is formed in at least two layers with an upper layer forming the outer side and a fabric layer forming an inner layer, preferably made of polyester fiber material.

[0069] The inner layer can form a smooth fabric layer, which can also be jacquarded and, for example, provided with a pattern, and on which the upper layer of the 3D spacer knit made of textured, twisted yarn, in particular multifilament yarn, can be formed towards the outside.

[0070] The honeycomb-like recesses can extend at least substantially across the entire thickness of the upper layer, i.e., from the outer side, optionally through one or more middle layers, to the inner layer or close to it, to enable optimal climate control with regard to air and moisture exchange between the two sides of the cover fabric. Furthermore, the depth of the honeycomb-like recess increases the softness of the upper layer made of 3D spacer knit, thus achieving an improved feel.

[0071] The cover fabric and / or mattress cover can also be constructed in three layers. For example, the cover fabric can have a middle layer knitted with the upper layer, with a monofilament yarn as a filler. This can achieve stabilization and a tactile volume of the 3D spacer knit, which is often desired, while simultaneously achieving high air and moisture permeability. According to a preferred embodiment, the monofilament yarn can be made of polyester, but other synthetic fibers, such as polyamide, can also be used.

[0072] In order to give the outward-facing surface or outer side of the spacer fabric, the cover material and / or the mattress cover a particularly smooth and pleasant feel, the surface of the cover material and / or the mattress cover surrounding the honeycomb-like recesses can be formed from particularly fine knitted stitches.

[0073] Studies have shown that, in terms of comfort and microclimatization, it is particularly advantageous if the upper layer of the spacer knit has a weight percentage of 50% to 70%, particularly 55% to 60%, of the cover fabric and / or mattress cover. The inner layer can have a weight percentage of 20% to 30%, particularly 25% to 30%, of the cover fabric and / or mattress cover.

[0074] When using a filler, optimal results in terms of air permeability, stabilization and volumization were determined with a weight proportion of 10% to 20%, in particular 15% to 20%, of the middle layer of the cover fabric and / or the mattress cover.

[0075] The cover fabric and / or the mattress cover can have a weight of 200 g / m 2 up to 300 g / m 2which means it can have the required durability and at the same time be easy to handle in terms of its weight during production and use.

[0076] Optionally, the mattress cover can be made at least partially from a natural fiber in the upper and / or lower layers of the cover material. The use of natural fibers, which can be contained and / or knitted into the spacer knit, for example, can increase the sustainability and / or ecology of the moisture protection cover, for example because the natural fibers can be obtained from renewable raw materials. Natural fibers can also be characterized by increased resilience and / or durability. Furthermore, natural fibers can result in a pleasant, soft feel for the user. Natural fibers can also be characterized by increased skin compatibility, breathability, and / or odor neutrality. Furthermore, natural fibers can enable cost-efficient production of the cover.

[0077] According to one embodiment, the natural fiber is an animal hair fiber, a wool fiber, a cotton fiber, a hemp fiber, a eucalyptus fiber, a bamboo fiber, a linen fiber, a wood fiber, a viscose fiber, a flax fiber, a silk fiber, a plant fiber, or a combination thereof. Such natural fibers can be characterized by increased sustainability, odor neutrality, skin compatibility, durability, and / or robustness compared to synthetic fibers.

[0078] According to one embodiment, the upper layer, the lower layer, and / or one or more middle layers of the cover material have a weight fraction of natural fibers, approximately based on the respective layer or the entire cover material, of 2% to 99%, for example at least 5%, at least 10%, at least 15%, at least 20%, and / or at least 25%. At least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, or 75% of natural fibers is also conceivable.

[0079] According to one embodiment, the proportion, for example the weight proportion and / or volume proportion of natural fibers, relative to the respective layer or the entire cover material, in the upper layer is greater than the proportion, for example the weight proportion and / or volume proportion, of natural fibers in the lower and / or one or more middle layers. For example, the proportion in the upper layer can be at least twice as large as the corresponding proportion of natural fibers in the lower and / or one or more middle layers.

[0080] According to one embodiment, the upper layer consists essentially and / or almost entirely, for example entirely, of natural fibers and the lower layer, as well as optionally one or more middle layers, consist essentially and / or almost entirely, for example entirely, of synthetic fibers.

[0081] The mattress cover made of spacer knit fabric can be formed on all sides of the mattress, i.e., in particular, on the first half and the second half of the mattress cover. Alternatively, for example, only the first half or the second half of the mattress cover can be made of spacer knit fabric.

[0082] Below you will find examples of possible designs for mattress covers.

[0083] The mattress cover can comprise a cover material and / or be formed from a cover material which comprises a 3D spacer knit at least on one outer side of the mattress cover and on the outer side has a honeycomb-like mesh structure with outwardly open recesses.

[0084] The cover material and / or the mattress cover can be made of at least two layers of 3-D spacer knit with an upper layer of textured, twisted yarn, in particular multifilament yarn, forming the outer side of the mattress cover (or the cover material) and a layer of preferably smooth polyester yarn forming an inner layer.

[0085] The cover material and / or the mattress cover can be formed in three layers with a middle layer knitted with the upper layer with a monofilament yarn as filler, wherein the monofilament yarn is preferably formed from polyester or polyamide.

[0086] The honeycomb-like recesses may extend at least substantially over the thickness of the upper layer and, if appropriate, the thickness of the middle layer.

[0087] The upper layer may have a weight share of 50% to 70%, in particular 55% to 60%, of the cover material and / or the mattress cover.

[0088] The inner layer may have a weight share of 20% to 30%, in particular 25% to 30%, of the cover material and / or the mattress cover.

[0089] The middle layer can have a weight share of 10% to 20%, in particular 15% to 20%, of the cover material and / or the mattress cover.

[0090] The cover fabric and / or mattress cover can have a mass per unit area of ​​approximately 250 g / m 2 up to 300 g / m 2 have.

[0091] The cover fabric and / or the mattress cover can be the same on all sides of the mattress.

[0092] Further features, advantages and possible applications of the invention will become apparent from the following description of the embodiments and figures.

[0098] Detailed description of implementation examples

[0099] Figure 1 shows a schematic plan view of a mattress 10 according to an embodiment of the invention. Figure 2 shows a perspective view of the mattress 10 from Figure 1.

[0100] The mattress 10 has a first half 12a and a second half 12b, which are arranged one behind the other along a longitudinal axis 14 of the mattress 10. The longitudinal axis 14 can, as indicated by way of example in Figure 1, run parallel to the x-axis shown in Figure 1. A longitudinal direction, i.e. the x-axis, of the mattress 10 can run parallel to the longitudinal axis 14. Transverse and / or orthogonal to the longitudinal axis 14, the mattress 10 has a transverse axis 16, which can run parallel to the y-axis of Figure 1. A transverse direction, i.e. the y-axis, of the mattress 10 can run parallel to the transverse axis 16. The transverse axis 16 shown in Figure 1 can designate a central transverse axis 16, which separates the halves 12a and 12b and / or delimits them from one another. In Figure 2, a central transverse plane 17 through the mattress 10 is illustrated in the area of ​​the central transverse axis 16.The central transverse plane 17 can lie in a plane spanned by the transverse axis 16 and a vertical axis (not shown) of the mattress 10, or z-axis. A vertical direction of the mattress 10 can run parallel to the vertical axis, or z-axis. The vertical axis can run parallel to the z-axis of Figure 2, as well as transversely and / or orthogonally to the longitudinal axis 14 and the transverse axis 16. A length of the mattress 10 can be parallel to the longitudinal axis 14, a width of the mattress 10 can be parallel to the transverse axis 16, and a thickness (or height) of the mattress 10 can be parallel to the vertical axis (z-axis).

[0101] Figure 1 schematically illustrates the individual regions and / or support regions of the mattress 10. The mattress 10 has, in the first half 12a, a first head support region 20a, a first neck support region 22a, a first shoulder support region 24a, a first lordosis support region 26a, and a first pelvic support region 28a, which are arranged one behind the other from a first end 18a of the mattress 10 in the direction of the central transverse axis 16 and / or the central transverse plane 17 of the mattress 10.

[0102] Analogous to the first half 12a, the mattress 10 has in the second half 12b a second head support region 20b, a second neck support region 22b, a second shoulder support region 24b, a second lumbar support region 26b, and a second pelvic support region 28b, which are arranged one behind the other from a second end 18b of the mattress 10, opposite the first end 18a in the longitudinal direction of the mattress 10, in the direction of the central transverse axis 16 and / or the central transverse plane 17 of the mattress 10. The first half 12a and the second half 12b of the mattress 10 are thus symmetrical, in particular mirror-symmetrical, with respect to the regions 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b, 28a, 28b relative to the central transverse axis 16 and / or the central transverse plane 17.

[0103] Fig. 2 shows a perspective sectional view along the longitudinal axis 14 of the mattress 10 from Figure 1, i.e. a longitudinal section through the mattress. The mattress 10 has a first mattress element 30 with a first outer surface 32 and a first contact surface 34 arranged opposite the first outer surface 32. The first outer surface 32 forms a first lying surface 32 for a user. Furthermore, the mattress 10 has a second mattress element 40 with a second outer surface 42, which serves as a second lying surface 42 for the user, and a second contact surface 44 arranged opposite thereto. As described above and below, the first lying surface / outer surface 32 can differ from the second lying surface / outer surface 42 in terms of a degree of firmness, so that the user can select the suitable or appropriate degree of firmness for him by turning the mattress 10 over.

[0104] The first mattress element 30 and the second mattress element 40 are arranged one above the other and / or stacked on top of the other such that the first contact surface 34 of the first mattress element 30 is at least partially in contact with the second contact surface 44 of the second mattress element 40. The first contact surface 34 can thus be at least partially placed on and / or rest on the second contact surface 44 (and / or vice versa).

[0105] The mattress elements 30, 40 can have substantially identical lengths, widths, and / or thicknesses. Alternatively, the thickness of the first mattress element 30 can differ from the thickness of the second mattress element 40. The thickness of the first mattress element 30 and / or the second mattress element 40 can be influenced by the degree of hardness of the material used for the respective mattress elements 30 and 40. Different degrees of hardness of the mattress elements 30 and 40 are represented or indicated by different colors of the foams / material.

[0106] As can be clearly seen in Figure 2, the first contact surface 34 of the first mattress element 30 is planar, smooth, and / or flat, in particular completely planar, smooth, and / or flat. In other words, the first mattress element 30 has no structure, profile, and / or indentations on the first contact surface 34 (apart from unevenness in the material of the first mattress element 30). Alternatively, however, a profile can also be provided on the first contact surface 34.

[0107] At least in a partial area, the second contact surface 34 of the second mattress element 40 has a profile 36 with a plurality of recesses 38. The recesses 38 of the second contact surface 44 are designed as transverse grooves 38, which extend across the entire width of the mattress 10 and / or the second mattress element 40, each parallel to the transverse axis 16, and project parallel to the vertical axis into the second mattress element 40, i.e., into the interior volume of the second mattress element 40. In the present disclosure, recesses 38 may also be referred to as recesses 38 and / or transverse grooves 38.

[0108] As can be seen in Figure 2, the recesses 38 of the profile 36 of the second contact surface 44 have a substantially rectangular cross-section and / or a substantially rectangular cross-sectional geometry. The individual rectangular recesses 38 are open to the outside and / or in a direction parallel to a surface normal vector of the second contact surface 44. In the cross-section of Figure 2, the profile can therefore be seen as a tooth-shaped profile with multiple teeth. The recesses 38 are delimited by the first contact surface 34 of the first mattress element 30.

[0109] Corners of the cross-section of the rectangular recesses 38 are essentially pointed, i.e., formed at a 90° angle, but can alternatively also be rounded. In principle, the recesses 38 can have any other cross-sectional geometry. For example, a cross-section and / or a cross-sectional geometry of the recesses 38 can also be triangular, oval, round, elliptical, T-shaped, square, trapezoidal, and / or polygonal. The recesses 38 are formed in particular in the two head support areas 20a, 20b, the two neck support areas 22a, 22b, the two shoulder support areas 24a, 24b, and / or in the two lumbar support areas 26a, 26b. The number of rectangular recesses 38 per region 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b of the second contact surface 44 is basically arbitrary. For example, 22, ie11 each per half of the mattress 10, recesses provided in the areas 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b.

[0110] A dimension and / or width of the recesses 38 measured parallel to the longitudinal axis 14 of the mattress 10 can, for example, be between approximately 0.5 cm and 5 cm, in particular between 1 cm and 3 cm. A depth of the recesses 38 measured parallel to the vertical axis can be approximately between 0.5 cm and 5 cm, for example between 1 cm and 3 cm.

[0111] Directly adjacent depressions 38 of the rectangular depressions 38 can be substantially equally spaced from one another, wherein a distance between adjacent depressions 38 can be dimensioned parallel to the longitudinal axis 14 of the mattress 10. Directly adjacent depressions 38 can also be spaced from one another at different distances than other directly adjacent depressions 38. The distance between directly adjacent depressions 38 of the rectangular depressions 38 can be substantially equal to the width of the depressions 38. The depth of the depressions 38 can be dimensioned, starting from the second contact surface 44, parallel to the vertical axis (or z-axis) of the mattress 10. The width can be dimensioned parallel to the longitudinal axis 14 of the mattress 10.

[0112] The profile 36 can optionally be designed symmetrically, for example mirror-symmetrically, relative to the central transverse axis 16. In the embodiment shown in Figure 2, the profile 36 is shown mirror-symmetrically to the center plane of the mattress.

[0113] On the first outer surface 32, the first mattress element 30 further has a profile 46 with a plurality of recesses 48, depressions 48, and / or transverse grooves 48. The recesses 48 extend completely through the first mattress element 30, starting from a first transverse side of the first mattress element 30 to an opposite second transverse side of the first mattress element 30. The recesses 48 have, for example, a round, T-shaped, semicircular, and / or circular cross-section. Alternatively, however, the recesses 48 can also have any other cross-section, such as a square, elliptical, polygonal, and / or teardrop-shaped one. Each of the recesses 48 is spaced from the first outer surface 32 in a direction parallel to the vertical axis of the mattress 10, so that each of the recesses 48 extends in an internal volume of the first mattress element parallel to the transverse axis 16 through or into the first mattress element 30.

[0114] A vertical distance, measured parallel to the vertical axis, between the first outer surface 32 and each of the recesses 48, in particular the deepest point of the recesses 48, depends on the corresponding shape or cross-sectional area of ​​the recesses 48. For example, recesses 48 with a circular cross-sectional area have a greater distance than recesses 48 with a T-shaped cross-sectional area or recesses 48 with a semicircular cross-sectional area. In other words, the corresponding depth of the recesses 48 depends on their cross-sectional area.

[0115] Each of the recesses 48 is opened via an incision 47 in the direction of the first outer surface 32, wherein the incisions 47 extend parallel to the recesses 48 across the entire width of the mattress 10. The recesses 48 are connected, as it were, to the first outer surface 32 via the incisions 47. Thus, apart from the incisions 47, there is a (thin) layer of material from the first mattress element 30 between each of the recesses 48 and the first outer surface 32. Thus, apart from the incisions 47, the recesses 48 are each covered by a layer of material from the first mattress element 30, so that the recesses 48 are not or hardly noticeable for a user standing on the first outer surface 32.

[0116] In the example of Figure 2, the recesses 48 are formed at least partially in the headrest areas 20a, 20b, the neck support areas 22a, 22b, the shoulder support areas 24a, 24b, the lumbar support areas 26a, 26b, and the pelvic support areas 28a, 28b of the first mattress element 30. In detail, one recess 48 with a T-shaped cross-sectional area is provided in each of the headrest areas 20a, 20b. Five recesses 48 with a circular cross-sectional area are provided in each of the shoulder support areas 24a, 24b. One recess 48 with a semicircular cross-sectional area is provided in each of the lumbar support areas 26a and 26b. Three recesses with a T-shaped cross-sectional area are provided in the pelvic support areas 28a and 28b. No recesses 48 can be provided in the neck support areas 22a, 22b.However, more or fewer recesses 48 can be provided in each of the regions or each half 12a, 12b. The recesses 48 with a circular cross-sectional area have an identical depth. The recesses 48 with a T-shaped cross-sectional area have an identical depth. The recesses 48 with a semicircular cross-sectional area have an identical depth.

[0117] On the second outer surface 42, the second mattress element 40 further has a further profile 50 with a plurality of recesses 52, depressions 52, and / or transverse grooves 52. The recesses 52 extend completely through the second mattress element 40, starting from a first transverse side of the second mattress element 40 to an opposite second transverse side of the second mattress element 40. The recesses 52 have, for example, a round, triangular, T-shaped, semicircular, and / or circular cross-section. Alternatively, however, the recesses 52 can also have any other cross-section, such as a square, elliptical, polygonal, and / or teardrop-shaped one. Each of the recesses 52 is spaced apart from the second outer surface 42 in a direction parallel to the vertical axis of the mattress 10, so that each of the recesses 52 extends through or into an inner volume of the second mattress element 40 parallel to the transverse axis 16.extends into the second mattress element 40. A vertical distance, measured parallel to the vertical axis, between the second outer surface 42 and each of the recesses 52 is smaller than a distance between the second contact surface 44 and each of the recesses 52.

[0118] A distance, measured perpendicular and parallel to the vertical axis, between the second outer surface 42 and each of the recesses 52, in particular the deepest point of the recesses 52, depends on the corresponding shape or cross-sectional area of ​​the recesses 52. The recesses 52 formed on the second outer surface 42 have a larger diameter, at least partially a larger cross-sectional area and / or a larger dimension than the recesses 48. Starting from each end of the shoulder support regions 24a, 24b of the mattress 10, a diameter of the recesses 52 decreases in the direction of the central transverse axis only in the shoulder support regions 24a, 24b, in particular decreases gradually. The diameters of the recesses 52 can also decrease continuously in the direction of the central transverse axis 16 in the shoulder connection regions 24a, 24b.Accordingly, the corresponding depth of the recesses 52 also decreases gradually in the direction of the central transverse axis 16 in the shoulder closure regions 24a, 24b.

[0119] Each of the recesses 52 is opened via an incision 54 in the direction of the second outer surface 42, wherein the incisions 54 extend parallel to the recesses 52 across the entire width of the mattress 10. The recesses 52 are connected, as it were, to the second outer surface 42 via the incisions 54. Thus, apart from the incisions 54, there is a thin layer of material from the second mattress element 40 between each of the recesses 52 and the second outer surface 42. Thus, apart from the incisions 54, the recesses 52 are each covered by a layer of material from the second mattress element 40, so that the recesses 52 are not or hardly noticeable for a user standing on the second outer surface 42.

[0120] In the example of Figure 2, the recesses 52 are formed at least partially in the headrest areas 20a, 20b, the neck support areas 22a, 22b, the shoulder support areas 24a, 24b, the lumbar support areas 26a, 26b, and the pelvic support areas 28a, 28b of the first mattress element 30. In detail, one recess 52 with a T-shaped cross-sectional area is provided in each of the headrest areas 20a, 20b. Five recesses 52 with a circular cross-sectional area are provided in each of the shoulder support areas 24a, 24b. One recess 52 with a semicircular cross-sectional area is provided in each of the lumbar support areas 26a and 26b. In the pelvic support areas 28a and 28b, three recesses 52 with a triangular cross-sectional area are provided.The three recesses 52 with triangular cross-sectional areas in the pelvic support regions 28a and 28b differ at least partially in their cross-sectional area. In other words, the two recesses 52a which are spaced furthest apart from each other are identically designed, but can also be differently designed. These recesses 52a which are spaced furthest apart from each other differ from the last recess 52a which is arranged or provided between the two recesses which are spaced furthest apart from each other. The recesses 52a which are spaced furthest apart from each other have a depth of 30 mm, or extend 30 mm into the internal volume of the second mattress element 40. The recess 52a which is arranged between the recesses which are spaced furthest apart from each other has a depth of 25 mm, orextend 25 mm into the interior volume of the second mattress element 40. The three recesses 52a are open toward or towards the second outer surface 42 and form openings of 30 mm there. Alternatively, the recesses 52a with a triangular cross-sectional area can also extend into the second mattress element 40 with a range of 10 mm to 60 mm. Furthermore, the cross-section of the recesses 52a can increase or decrease gradually or continuously.

[0121] No recesses 52 may be provided in the neck support areas 22a, 22b. However, more or fewer recesses 52 may be provided in each of the areas or each half 12a, 12b. The recesses 52 with a T-shaped cross-sectional area have an identical depth. The recesses 52 with a semicircular cross-sectional area have an identical depth.

[0122] A dimension measured parallel to the longitudinal axis 14 of the mattress 10 and / or a diameter of the recesses 52, 48 can, for example, be between approximately 0.5 cm and 7 cm, in particular between 1 cm and 5 cm.

[0123] Furthermore, the profiles 46, 50 and / or the recesses 48 and 52 can be arranged and / or formed symmetrically, in particular mirror-symmetrically, to one another relative to the central axis 16 and / or to the central transverse plane 17.

[0124] By forming the profiles 46 and 50 of the first and second mattress elements 30, 40, at least partially different support properties and / or compression hardnesses can advantageously be provided in the regions 20a, 20b, 22a, 22b, 24a, 24b, 26a, 26b, 28a, 28b of the mattress 10.

[0125] As can further be seen in Figure 2, the profile 46 of the first outer surface 32 of the first mattress element 30 differs at least partially from the profile 50 of the second outer surface 42 of the second mattress element 40. For example, more, the same number, or fewer recesses 48 are formed on the second outer surface 42 than on the first outer surface 32.

[0126] Figures 3 and 4 each show a mattress 10 according to exemplary embodiments. Unless otherwise described, the mattress 10 of Figures 3 and 4 has the same elements and features as the mattress 10 of Figures 1 and 2. The mattress 10 has a mattress cover 60, which at least partially, in particular completely, encloses and / or wraps the first mattress element 30 and the second mattress element 40.

[0127] The mattress cover 60 has a first or upper half 62 and a second or lower half 64, which can be at least partially connected to one another with a zipper 66 along at least part of an outer circumference of the mattress 10, for example along the side surfaces and / or end faces of the mattress 10. The first half 62 of the mattress cover 60 can cover at least the first lying surface 32 and / or the first outer surface 32 of the first mattress element 30. The second half 64 of the mattress cover 60 can cover at least the second lying surface 42 and / or the second outer surface 42 of the second mattress element 40.

[0128] The mattress cover 60 can be opened and completely removed via the closure 66, for example, to wash the mattress cover 60. The mattress cover 60 can be washed, in particular, at a washing temperature of up to approximately 75° Celsius, for example, up to approximately 60° Celsius, which can advantageously simplify and / or enable comprehensive cleaning of the mattress cover 60.

[0129] The halves 62, 64 of the mattress cover 60 can differ, for example, in terms of the type of fabric and / or the fabric structure of the cover material used for the halves 62, 64. The cover material of the first half 62 of the mattress cover 60 can, for example, be single-layered or multi-layered. For example, the cover material of the first half 62 of the mattress cover 60 can have an upper layer forming an outer fabric, which can serve as a support surface for the user. In addition, the cover material of the first half 62 of the mattress cover 60 can have a lower layer, which can be at least partially in contact with the first outer surface 32 of the first mattress element 30. A layer of wadding, such as a layer of polyester wadding and / or climate wadding, can optionally be arranged between the upper layer and the lower layer. This can impart a pleasantly soft feel and a certain compressibility and / or volumization to the cover material.The cover material of the first half 62 of the mattress cover 60 can further comprise honeycomb-like and / or honeycomb-shaped depressions 70, which can be arranged in a regular pattern in the cover material. As an alternative to the depressions 70, the mattress cover 60 can have a pattern 70, similar to an embossing, at least in a partial area. The honeycomb-like depressions 70 can advantageously fix the wadding layer between the upper layer and the lower layer. The cover material of the second half 64 of the mattress cover 60 can also be designed analogously and / or identically to the cover material of the first half 62 of the mattress cover 60.

[0130] Alternatively, however, the cover material of the second or lower half 64 of the mattress cover 60 can differ from the cover material of the first or upper half 62 of the mattress cover 60, in particular with regard to a construction, a type of fabric, a material composition, and / or a fabric structure. For example, the cover material of the second half 64 of the mattress cover 60 can be siliconized and / or rubberized. For example, a latex layer can be applied to an outer surface of the cover material of the second half 64 of the mattress cover 60. This can, in particular, prevent the mattress 10 from slipping on a support surface, such as a bed. This can be particularly advantageous for box spring beds, since here the mattress 10 is usually not held laterally by the bed's boundary surfaces.

[0131] Optionally, the halves 62, 64 of the mattress cover 60 can differ in terms of the color of the cover material. This can make it possible to indicate to the user, through the structure and / or color of the respective half 62, 64 of the mattress cover 60, which side and / or which of the first and second sleeping surfaces 32, 54 has the desired degree of firmness. Thus, the user can identify and / or select the sleeping surface 32, 54 that is suitable for them without, for example, removing the mattress cover 60.

[0132] Optionally, the thickness of the two halves 62, 64 of the mattress cover 60 can be different. For example, the upper / first half 62 can have a smaller thickness than the lower / second half 64. This can mean that the upper / first half 62 covers a smaller portion of the thickness of the mattress 10 in the vertical direction of the mattress 10 than the lower / second half 64. In the example of Figure 4, the upper / first half covers approximately 1 / 3 of the thickness of the mattress 10, and the lower / second half covers approximately 2 / 3 of the thickness of the mattress 10. A 50 / 50 split or any other split is also conceivable in principle.

[0133] Furthermore, the mattress cover 60 has two carrying handles 65 on each side surface of the mattress 10, with the aid of which the mattress 10 can be transported. The carrying handles 65 can be made of a fabric. For example, the carrying handles 65 can be made of the cover material of the first and / or second half 62, 64 of the mattress cover 60 and / or, for example, of a spacer knit, as described above and below with reference to the cover material of the first and / or second half 62, 64. The carrying handles 65 can have a length of approximately 15 cm to 25 cm, measured parallel to the longitudinal axis 14. The carrying handles 65 can be arranged on the first half 62 of the mattress cover 10 or, as shown in Figure 4, on the second half 64 of the mattress cover. Carrying handles 65 can also be provided on both halves 62, 64.

[0134] As can be seen in Figure 4, the zipper 66 is not centrally positioned, so that the first half 62 has a smaller thickness (or height - measured parallel to the vertical axis) than the second half 64 of the mattress cover 60. This allows the carrying handles 65 to be wider and thus mechanically more stable. A width of the carrying handles measured parallel to the vertical axis of the mattress 10 can be approximately 2 cm to 5 cm. The arrangement of the zipper 66 can also indicate a degree of hardness of the respective sleeping surface 32, 54.

[0135] Alternatively, however, the zipper 66 may also be arranged centrally so that the halves 62, 64 of the mattress cover 60 can have substantially identical thicknesses and / or heights (measured parallel to the vertical axis).

[0136] Alternatively, or in addition to the above regarding the cover material of the first and second halves 62, 64 of the mattress cover 60, the mattress cover 60 can be made at least partially, in particular entirely, from a spacer knit, such as a three-dimensional spacer knit, wherein the mattress cover 60 (or the spacer knit) has a honeycomb structure with outwardly open recesses on its outer side (the side facing the user). This can advantageously provide a breathable surface for the mattress 10, which can further improve lying comfort for the user. A mattress cover 60 made from a spacer knit can also have an advantageous effect on the feel, particularly compared to a mattress cover made from a spacer knit, so that the mattress cover 60 can feel soft and not scratchy.The honeycomb-like recesses can, for example, have elliptical cross-sections. However, any other cross-sections are also possible, in particular round, oval, angular and / or polygonal cross-sections. The spacer fabric can be multi-layered, in particular two-layered or three-layered. The first and second halves 62, 64 of the mattress cover 60 can generally be made of an identical cover material or of different cover materials. It should also be noted that "comprising" and "having" do not exclude other elements, and "a" or "an" does not exclude a plurality. Furthermore, it should be noted that features described with reference to one of the above exemplary embodiments can also be used in combination with other features of other exemplary embodiments described above. Reference symbols in the claims are not to be regarded as limitations.
