Description

According to an embodiment, the top layer and / or the bottom layer of the cover fabric is formed at least partially from a natural fiber. The use of natural fibers, which can be contained and / or knitted in the weft-knitted fabrics, for example, can increase the sustainability and / or ecology of the mattress cover (hereinafter also referred to as "cover"), for example because the natural fibers can be obtained from renewable raw materials. Natural fibers may also be characterized by increased resilience and / or durability. In addition, natural fibers may result in a pleasant, soft feel for the user. Also, natural fibers may be characterized by increased skin tolerance, breathability and / or odor neutrality. In addition, natural fibers can enable cost-efficient production of the mattress cover. According to an embodiment, the natural fiber is an animal hair fiber, a wool fiber, 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 may be characterized, for example, by increased sustainability, odor neutrality, skin compatibility, durability, and / or robustness compared to synthetic fibers. According to an embodiment, the upper layer, the lower layer and / or one or more middle layers of the upholstery fabric have a proportion by weight of natural fibers, relative to the respective layer or the entire upholstery fabric, of 2% to 99%, for example at least 5%, at least 10%, at least 15%, at least 20% and / or at least 25%. Also at least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, or 75% of natural fibers is conceivable. According to an embodiment, the proportion, such as the weight proportion and / or the volume proportion, of natural fibers, such as related to the respective layer or the entire cover fabric, in the upper layer is greater than the proportion, such as the weight proportion and / or the volume proportion, of natural fibers in the lower layer and / or one or more middle layers. For example, the proportion in the upper layer may be at least twice as large as the corresponding proportion of natural fibers in the lower and / or one or more middle layers. According to an embodiment, the top layer consists essentially and / or almost entirely, for example entirely, of natural fibers and the bottom layer, and optionally one or more middle layers, consist essentially and / or almost entirely, for example entirely, of synthetic fibers. According to an embodiment, the upper layer and / or the lower layer of the cover fabric is formed at least partially from textured, twisted yarn, in particular multifilament yarn, for example polyester yarn, polyethylene yarn, polyamide yarn, polyethylene yarn and / or polyamide yarn. This can provide a soft and pleasant feel. According to an embodiment, the upper layer and / or the lower layer of the cover fabric is formed at least partially from monofilament yarn, in particular polyester yarn, smooth polyester yarn, polyethylene yarn, smooth polyethylene yarn, polyamide yarn, and / or smooth polyamide yarn. When the cover fabric is formed from monofilament yarn on the underside of the cover fabric facing the mattress core or the pillow core, removal or insertion of the mattress core or pillow core can be facilitated. For example, the cover fabric can be formed from weft-knitted fabrics in at least two layers, with an upper layer forming the outer side and a fabric layer forming an inner or lower layer, preferably of polyester fiber fabric, polyethylene fiber fabric and / or polyamide fiber fabric. The inner or lower layer can, for example, be a smooth fabric layer, which can also be jacquardized and / or provided with a pattern, for example, on which the upper layer of the weft-knitted fabrics made of textured, twisted yarn, in particular multifilament yarn, can be built up towards the outside. According to an embodiment, the cover fabric further comprises a middle layer which is at least selectively and / or at least partially knitted with the top layer and / or the bottom layer. The middle layer can serve to volumize the cover fabric. In this way, lying comfort can also be increased. According to an embodiment, the middle layer is at least partially formed from a monofilament yarn, in particular polyester yarn, smooth polyester yarn, polyethylene yarn, smooth polyethylene yarn, polyamide yarn, and / or smooth polyamide yarn. According to an embodiment, the middle layer is formed at least in part from a multifilament yarn, for example, a textured twisted multifilament yarn, for example, polyester yarn, polyethylene yarn, polyamide yarn, polyethylene yarn, and / or polyamide yarn. According to an embodiment, the middle layer is at least partially formed from a natural fiber. This offers the advantages explained above with regard to natural fibers. According to an embodiment, the recesses extend at least substantially through a thickness of the top layer and optionally the middle layer. In particular, the recesses can extend completely through the upper layer, so that the recesses can form and / or represent apertures in the upper layer, as it were. For example, the recesses may extend at least substantially across the entire thickness of the top layer, that is, from the outside to or close to the inner or bottom layer, such as to allow optimal climate control with respect to air and moisture exchange between the two sides of the cover fabric. In addition, the depth of the recess can increase the softness of the upper layer of weft-knitted fabrics, thus obtaining an improved feel. The cover fabric can further be formed in three layers with a middle layer, such as a layer knitted with the upper layer, with a monofilament yarn as filler. In this case, stabilization and a haptically frequently desired voluminization of the weft-knitted fabrics can be achieved with simultaneous high air and moisture permeability. The monofilament yarn can, for example, be formed at least partially from polyester, polyamide and / or polyethylene, but other synthetic fibers can also be used for this purpose. To give the outward-facing surface or outer side of the weft-knitted fabrics a particularly smooth and pleasant feel, the surface or outer side surrounding the recesses can be formed from finer knit stitches compared to other areas of the outer side. According to an embodiment, the top layer has a weight proportion of 50% to 70%, in particular 55% to 60%, of the cover fabric. Investigations have shown that this proportion by weight is particularly advantageous in terms of comfort and microclimatization. According to an embodiment, the bottom layer has a weight percentage of 20% to 30%, in particular 25% to 30%, of the cover fabric. According to an embodiment, a middle layer has a weight percentage of 10% to 20%, in particular 15% to 20%, of the cover fabric. When using a filler, optimum results in terms of air permeability, stabilization and volumization were determined at a weight content of 10% to 20%, in particular 15% to 20%, of the middle layer on the cover fabric. According to an embodiment, the cover fabric has a weight of 250 g / m2 - 300 g / m2. This enables the upholstery fabric to comprise the required durability and at the same time to be easy to handle in terms of its weight during manufacture as well as during use. According to an embodiment, the cover fabric is rubberized, coated and / or provided with latex on at least one side, for example the outer side, the inner side, the bottom side and / or the top side, for example to prevent moisture and / or water from penetrating. According to an embodiment, the cover fabric is formed identically on all sides. In other words, the mattress cover can be formed identically on all sides, i.e. on the top side, on the bottom side and on the longitudinal and transverse sides, if present, although it is also conceivable in principle to form different sides of the cover differently. The identical design of all sides can enable particularly simple production, whereby the high breathability of the cover fabric also means that a ventilation strip on the transverse and longitudinal sides, which is frequently found in known covers, in particular mattress covers, can be dispensed with. According to an embodiment, the mattress cover comprises an at least partially circumferential closure, in particular a zipper, to be opened or closed for inserting or removing a mattress core and / or a pillow core. In order to enable insertion and removal of a mattress core or a pillow core, it may be advantageous if the mattress cover comprises an at least partially circumferential closure, in particular a zipper. Furthermore, handles may be sewn to the mattress cover for easier handling of a mattress covered with the mattress cover and / or the reclining furniture. The mattress cover may further be washable, for example, at a temperature of at least 30°C, at least 40°C, at least 50°C, at least 60°C, at least 70°C, at least 80°C, or at least 90°C. Another aspect of the present disclosure relates to the use of a mattress cover for a reclining furniture as described above and below. The reclining furniture with mattress cover can be advantageous especially for indoor use of the reclining furniture. Instead of or additionally, the reclining furniture can also comprise an outer cover. The outer cover can enclose the base element, the mattress, and optionally the mattress cover at least partially, in particular completely. Optionally, a further outer cover can be provided, which can at least partially, in particular completely, enclose the outer cover. The further outer cover can, for example, be formed analogously to the mattress cover as described above and below. By providing the further outer cover, a lying comfort for the user can be increased and a protection against water can be ensured by the underlying outer cover and / or a further cover, in particular the basic furniture cover. According to an embodiment, the at least one reclining furniture cover is formed as an outdoor cover, in particular for use of the reclining furniture outdoors, wherein the outdoor cover is at least partially waterproof, washable and / or thermally insulating. According to an embodiment, the outer cover comprises silicone, rubber, polymer-based material, fiber material, fabric, latex, plastic, leather, synthetic leather, and / or plastic. Different materials, colors, haptics are conceivable and / or combinable for the outer cover. According to an embodiment, the outer cover comprises an at least partially circumferential closure, in particular a zipper, to be opened and / or closed for inserting and / or removing the mattress and / or the base element of the reclining furniture, wherein the closure is configured to be at least partially waterproof. This can be particularly advantageous for use of the reclining furniture outdoors or in harsh environments. According to an embodiment, the reclining furniture further comprises an anti-slip layer or ply deposited on the top layer of the base element and arranged between the base element and the mattress, wherein the anti-slip layer or ply is configured to prevent the mattress from sliding on the base element. The anti-slip layer or sheet may comprise, for example, rubber, silicone, latex or the like. According to an embodiment, the mattress comprises at least one head support region for supporting a head, at least one neck support region for supporting a neck, at least one shoulder support region for supporting shoulders, at least one lordosis support region for supporting at least a portion of a spine, and at least one pelvis support region for supporting a pelvis of the user. According to an embodiment, the head support area, the neck support area, the shoulder support area, the lordosis support area and the pelvis support area have profiles that are at least partially different from one another on the first and / or on the second side of the mattress. Such profiles can, for example, be profiling and / or structuring, so that a hardness, compression hardness and / or a degree of hardness of at least part of the individual support regions, i.e. head support region, neck support region, shoulder support region, lordosis support region and / or pelvic support region, differ from one another and / or so that the compression hardnesses of the mattress (or of mattress elements of the mattress) differ from one another at least in regions. The mattress can further optionally be a mattress and / or reversible mattress, which can provide different degrees of hardness. For ergonomic and comfortable lying, the mattress (or mattress elements thereof respectively) may be divided into different support areas and / or zones. In particular, the mattress may comprise one or more head support zones, one or more neck support zones, one or more shoulder support zones, one or more lordosis support zones, and one or more pelvic support zones. The different support areas can comprise different compression hardnesses, degrees of hardness and / or elasticities, so that the user sinks into or is supported by the outer surface to different depths in the respective support area. Also, a weight distribution of the user over at least a part of the first and / or second outer surface can be taken into account by the different support areas. For example, the different compression hardnesses of the support areas can take into account the fact that the user's head has a lower weight compared to the pelvis. The different compression hardnesses in the different support areas can further ensure that the spine or back of the user is straight, such as when the user is lying on his side, or comprises the typical S-shape, such as when the user is lying on his back. The different compression hardnesses in the respective support areas can be realized by using different materials, such as differently hard or soft mattress foam and / or polyurethane foam, by different profiles and / or by different structuring of the first and / or second outer surface. Such profiles may comprise, for example, grooves, corrugations, notches, cutouts, transverse grooves, recesses, channels, indentations and / or recesses. According to an embodiment, the mattress (or mattress elements thereof) comprises, relative to a transverse center axis and / or a transverse center plane, a first half and a second half which are arranged one behind the other along a longitudinal axis of the mattress. In each half, the mattress (or one or more mattress elements) comprises a head support region, a neck support region, a shoulder support region, a lordosis support region, and a pelvic support region. The two head support regions, neck support regions, shoulder support regions, lordosis support regions and pelvis support regions of the mattress (or one or more mattress elements), can thus be arranged in mirror symmetry relative to the central transverse axis and / or central transverse plane. According to an embodiment, the first half and the second half of the mattress (or one or more mattress elements) are formed symmetrically, in particular mirror-symmetrically, relative to the center transverse axis and / or center transverse plane of the mattress or the reclining furniture. In particular, with regard to a formation of the various support areas as well as a structuring and / or profiling of the various support areas, the mattress (or individual mattress elements) can be formed mirror-symmetrically. For example, the support regions may be formed in each of the first and second halves of the mattress (or one or more mattress elements) as described below. One head support region extends from each end of the mattress in the direction of the central transverse axis. One neck support region joins each of the head support regions and extends further in the direction of the central transverse axis of the. One shoulder support area shoots up to each of the neck support areas and extends further in the direction of the center transverse axis. One lordosis support area joins each of the shoulder support areas and extends in the direction of the center transverse axis. One pelvic support area joins each lordosis support area and extends to the center transverse axis. According to an embodiment, the first and / or the second side of the mattress comprises at least one recess and / or at least one transverse groove at least in a partial area. One or more transverse grooves can be formed in the individual support areas. Transverse grooves of different areas can differ, for example, in terms of number, geometry, cross section, size, depth or the like. The transverse grooves can extend essentially parallel to the transverse axis of the reclining furniture over the entire width of the first and / or second side of the mattress. Individual transverse grooves can be perceptible as macroscopic depressions, incisions or recesses. According to an embodiment, the mattress comprises at least two mattress elements which are at least partially stacked on top of each other. Alternatively or additionally, the mattress comprises at least a first mattress element and a second mattress element which are at least partially stacked on top of each other. The mattress may also comprise more than two mattress elements. A thickness of the mattress elements, which is dimensioned orthogonally to the longitudinal axis and to the transverse axis, can be identical to or different from one another. According to one embodiment, each of the two mattress elements comprises an outer surface and a contact surface, wherein the contact surface of the first mattress element is at least partially in contact with the contact surface of the second mattress element, and wherein at least one of the outer surfaces and / or contact surfaces of at least one of the first and second mattress elements comprises a profile, in particular a profile with one or more transverse grooves. For example, a profile may be provided on one or both of the outer surfaces. Optionally, a profile with one or more transverse grooves may additionally or exclusively be formed on one or both of the contact surfaces. In particular, profiles can be provided on one of the outer surface and the contact surface of each mattress element, which can have profiles that differ from one another. If a profile is provided on both contact surfaces, the profiles of the two mattress elements can optionally at least partially interlock and / or be formed to correspond to each other. According to an embodiment, the outer surface and / or the contact surface of the first mattress element comprises a first profile, and the outer surface and / or the contact surface of the second mattress element comprises a second profile, wherein the first profile differs at least partially from the second profile such that a degree of hardness of the first mattress element differs from a degree of hardness of the second mattress element. For example, the profiles may comprise different transverse grooves. The degree of hardness or compression hardness for the first and second mattress elements can further be influenced, for example, by the choice of material for the respective mattress element, e.g. different types of foam (such as polyurethane foam) can be selected. Furthermore, the degree of hardness can be influenced by corresponding structures, such as grooves, transverse grooves, beads, grooves, incisions, cutouts, recesses, channels, indentations and / or recesses, which can be formed, for example, in the first and / or second outer surface and / or the first and / or second contact surface. Furthermore, the connection of the first mattress element to the second mattress element can also be influenced, in particular by the choice and / or design of a profile, on at least one of the contact surfaces. Alternatively or additionally, the degree of hardness in the different areas of the mattress element may be different, for example by the choice of material, the profiling and / or the structuring of the respective outer surface and / or the design of the contact surface(s). For example, a shoulder support area may be designed to be slightly softer than a neck support area so that the user's shoulder sinks deeper into the outer surface of the mattress than the user's neck, particularly when the user is lying sideways on the respective outer surface of the mattress element. According to an embodiment, at least one of the first contact surface and the second contact surface has a profile with one or more transverse grooves at least in a partial area. This allows support properties to be further improved or influenced. According to an embodiment, the profile is formed exclusively on the second contact surface of the second mattress element. Alternatively or additionally, no profile is formed on the first contact surface of the first mattress element. According to an embodiment, the first contact surface and the second contact surface comprise mutually corresponding and / or at least partially interlocking profiles. For example, the profiles can interlock in a tooth-like manner to mutually fix the mattress elements. According to an embodiment, a degree of firmness of the first mattress element is greater than a degree of firmness of the second mattress element. The reverse may also be the case. According to an embodiment, at least one, in particular several, transverse groove extending in the transverse direction of the mattress is formed on the first outer surface of the first mattress element and / or on the second outer surface of the second mattress element between the at least one head support region and the at least one neck support region, which transverse groove has a T-shaped, trapezoidal and / or triangular cross section. The transverse groove can be formed, for example, as a groove, bead, groove, cutout, recess, channel, notch and / or recess, over the entire width in the transverse direction of the mattress (also referred to as a combination mattress). Generally, at least one transverse groove may be formed in at least one of the head support area, the neck support area, the shoulder support area, the lordosis support area, and the pelvis support area. In general, the profiles in the individual support areas can be given and / or defined by the transverse grooves or the absence of transverse grooves. Transverse grooves of different support areas may differ from each other with respect to their geometry, their cross-section, a depth of the respective transverse grooves, a dimension, a length and / or a width. As a result, the degree of hardness of the individual support areas can be varied and / or matched to one another. One or more transverse grooves may thereby comprise a drop-shaped, a circular, a triangular, a trapezoidal, a round, an oval, an elliptical or a T-shaped cross-section. In general, a depth of the transverse grooves dimensioned along the vertical axis may be about 1 to 5cm, and a width of the transverse grooves dimensioned along the longitudinal axis may be about 1 to 4cm. Optionally, one or more transverse grooves can also be made in the material of the mattress in such a way that they are at least partially covered on the outside by material of the mattress. According to an embodiment, at least one, in particular several, transverse groove extending in the transverse direction of the mattress is formed on the first outer surface of the first mattress element and / or on the second outer surface of the second mattress element in the at least one pelvic support region, which transverse groove has a T-shaped, trapezoidal, and / or triangular cross section. According to an embodiment, at least one, in particular several, transverse groove extending in the transverse direction of the mattress is formed on the first outer surface of the first mattress element and / or on the second outer surface of the second mattress element in the at least one shoulder support region, which transverse groove has a round, oval, teardropshaped and / or elliptical cross-section. According to an embodiment, a plurality of transverse grooves extending in the transverse direction of the mattress are formed on the first outer surface of the first mattress element in the at least one shoulder support region, which transverse grooves each have a round and / or teardrop-shaped cross-section, wherein the transverse grooves formed in the shoulder support region have identical diameters, cross-sections and / or sizes. The size of a transverse groove can designate a dimension, such as a width, of the respective transverse groove measured in the longitudinal direction of the mattress. According to an embodiment, a plurality of transverse grooves extending in the transverse direction of the mattress are formed on the second outer surface of the second mattress element in the at least one shoulder support region, which transverse grooves each have a round and / or teardrop-shaped cross-section, at least some of the transverse grooves formed in the shoulder support region having different diameters and / or sizes. The diameters, dimensions, widths and / or sizes of the transverse grooves can thereby decrease in the direction of the central transverse axis and / or the central plane. Another aspect of the present disclosure relates to the use of a reclining furniture as described above and below for reclining and / or sitting in an outdoor area, outdoors and / or in a harsh environment. Another aspect of the present disclosure relates to the use of a base element, as described above and below, for deforming and / or adjusting a mattress placed on the base element. In other words, the base element can be used in combination with any mattress which is placeable on the base element, in particular on the top layer thereof. Further features, advantages and possible applications of the disclosure will be apparent from the following description of the exemplary embodiments and figures.

Detailed description of exemplary embodiments Figure 1a shows an exploded view of a base element 100 according to an exemplary embodiment. Figure 1b shows an adjustment device 300 of the base element of Figure 1a. Figure 2 shows a top view of the base element 100 of Figure 1a. The base element 100 comprises a frame element 101a and a cover layer 101b. The base element 100 further comprises an adjustment device 300. The frame element 101a has a compartment 102, wherein the compartment 102 is formed and / or dimensioned such that the adjustment device 300 can be accommodated and / or integrated in the compartment 102. Thus, the adjustment device 300 is at least partially received in the compartment 102. The cover layer 101b of the base element is arranged on the frame element 101a. The frame element 101a may be formed partially or entirely of foam. Similarly, the cover layer 101b may be formed partially or entirely of foam. However, other materials are conceivable. The cover layer 101b may optionally include a cutout 114, which may be formed to provide space for mounting / dismounting one or more components of the adjustment device 300. The adjustment device 300, which is configured for deforming or adjusting the base element 100 and / or a mattress 202 placed thereon, comprises one or more drives 108, 108', for example two electric motors, and at least two rails 104, 104', which are arranged substantially parallel to each other and are connected to each other via at least one cross strut 103. Each of the rails 104, 104' thereby extends substantially parallel to a longitudinal axis 107 of the base element 100 and the at least one cross strut 103 extends substantially parallel to a transverse axis 109 of the base element 100. Each of the rails 104, 104' comprises, by way of example, three rail elements 105a, 106b, 105c, which are arranged one behind the other in the longitudinal direction of each rail 104, 104' and / or parallel to the longitudinal direction 107. The rail elements 105a, 105b and 105b and 105c are each movably coupled to one another at their ends via a joint 106, so that the rail elements 105a, 105b and 105b and 105c can be pivoted about an axis parallel to the transverse axis 109 via the joints 106. In the example of Figures 1a, 1b, and 2, the base element 100 or adjustment device comprises two drives 108, 108' and two drive mechanisms 115, 115'. Each drive mechanism may comprise one or more pulley mechanisms and / or gear mechanisms, which may be at least partially arranged and / or integrated in one or more rail elements 105a-105c. Further, the adjustment device comprises two crossbars 103, 103', each of which may be associated with a drive mechanism 115, 115'. A shaft 135 may be arranged in each of the cross struts 103, 103' and coupled to one of the drives 108, 108'. Alternatively, the cross struts 103, 103' can each form a shaft 135. The drives 108, 108' are thereby arranged on one of the two rails 104' and can actuate the drive mechanism located in the rail elements of this rail, for example a cable pull mechanism and / or a gear mechanism. The rotation of the respective drive 108, 108' can be transmitted to and actuate the oppositely arranged rail 104 and the drive mechanism located in the rail elements of this rail, such as a cable pull mechanism and / or a gear mechanism, via the associated shaft 135 or cross strut 103, 103'. In this way, portions 117a, 117b, 117c arranged between the rail elements 105a-105c opposing each other in pairs in the transverse direction 109 can be displaced, pivoted and / or tilted relative to each other. To extend the rails 104, 104' in the longitudinal direction 107, a longitudinal support strut 302 is arranged at each end of each rail element 105a, 105c, such as at each head end and / or foot end of each rail 104, 104',of the base element 100, which are spaced apart and coupled to each other via one or more transverse support struts 110 in the transverse direction 109. On the one hand, the areas 117a and 117c can thus be enlarged, a stability of the adjustment device 300 can be increased and the adjustment device 300 can withstand increased loads. In addition to the areas 117a-117c, areas extending beyond the front ends, head ends, and / or foot ends of the adjustment device 300 can also be individually displaced. Thus, in the example of Figures 1a, 1b, and 2, at least three, four, or five differently and individually adjustable regions may be created. More or fewer areas may also be provided. The adjustment device 300 further comprises a control circuitry 310 configured to control the adjustment device 300 and / or one or more drives 108, 108'. For example, the control circuitry 310 can be used to control a direction of rotation, a speed of rotation, or the like. This can be done via a suitable control signal. The control circuitry 310 further comprises an interface 112 coupled to a user interface 122 via a wired connection. The control unit 122 may comprise a user interface, such as a display, buttons, or the like, for controlling the control circuitry and / or the adjustment device 300. Alternatively or additionally, the control circuitry 300 has a wireless interface 312 for communicating with a receiver 120, such as a smartphone, tablet, PC, notebook, server, or the like, as shown in Figure 2. Further, the base element 100 includes an energy storage device 315, such as a battery or accumulator, for supplying electrical energy to the adjustment device 300. The energy storage device 315 can be charged, for example, via a cable that can optionally be routed through the frame element 101a and / or the cover layer 101b. Inductive charging or other techniques are also conceivable. Further, components of the adjustment device 300 may be configured to be at least partially waterproof. Figure 3 shows a base element 100 according to an exemplary embodiment. Unless otherwise described, the base element 100 of Figure 3 comprises the same elements and features as the base element 100 of Figures 1a to 2. The base element 100 of Figure 3 further has a base cover 301 in which the frame element 101a, the cover layer 101b and / or the adjustment device 300 are at least partially, in particular completely, accommodated.

Figures 4 and 5 each show a reclining furniture 200 according to an exemplary embodiment. The reclining furniture 200 comprises a base element 100 on which a mattress 202 having a first side 203 is arranged and / or laid. Opposite the first side 203, the mattress 202 forms a lying surface 205 for a user. The lying surface thereby faces a bottom surface 101 of the base element 100. The base element 100 of figures 4 and 5 may be formed like the base element 100 of the figures described above. The reclining furniture 200 further comprises at least one reclining furniture cover 204, which encloses the base element 100 and the mattress 202 at least partially, in particular completely.

In Figure 4, the reclining furniture 200 is shown in a horizontal position. In Figure 5, on the other hand, the individual areas 117a-117c are adjusted and / or displaced by the adjustment device 300, so that a total of at least four lying areas 401,402, 403, 404 on the reclining furniture 200 or the lying surface 205 are arranged and / or positioned differently relative to one another. The user can individually change, adjust and / or adapt the individual areas or reclining areas via one of the operating devices 120, 122. Figure 6 shows a perspective view of a mattress cover 204 of a reclining furniture 200 according to an exemplary embodiment. Figure 7 shows a highly simplified sectional top view of an outer side of the mattress cover 204 of Figure 6. Figure 8 shows a sectional schematic cross-sectional view through a cover fabric of the mattress cover 204 of Figures 6 and 7. Referring to Figure 6, an exemplary mattress cover 204 or mattress cover 204 is shown in a state stretched over a mattress 202 and a base element 100, wherein the cover 204 forms a first reclining surface on an upper surface 205 and optionally forms a second reclining surface for a user on an opposite lower surface 101. The mattress cover 204 is formed circumferentially from the same cover fabric 5, whereby lateral transverse surfaces 6 and longitudinal surfaces 7 also merge, optionally seamlessly, into the upper side 6 and lower side 7. Deviating from this, however, in other embodiments, a separation of the surfaces of the cover fabric 5 can also be provided by seams and, optionally, a welting tape. A circumferential closure 206 in the form of a zipper is sewn into the mattress cover 204 (or mattress cover 204) at the transverse surfaces 6 and longitudinal sides 7 for inserting and removing the mattress cover 202 and / or the base element 100. In addition, a plurality of handles 210 are provided on the lateral longitudinal surfaces 7 for lifting the base element 100 and / or the mattress 2020 encircled by the mattress cover 202 (or mattress cover 2), of which only one handle 210 is shown by way of example. As can be seen in a section X in Figure 6, which is representative of the entire surface of the mattress cover 204 (or mattress cover 204), and in Figures 7 and 8, the cover fabric 5 is formed with a weft-knitted fabric 10, such as a 3D weft-knitted fabric, to its outer surface 11. The cover fabric 5 comprises a honeycomb-like mesh structure with outwardly open recesses 12 in a regular, fine arrangement. In this respect, the recesses 12 preferably have a round, rounded, elliptical and / or oval cross-section towards the outside, which in the untensioned state may be dimensioned, for example, 2 mm to 4 mm in width and about 3 mm to 5 mm in length. The material webs 13 of weft-knitted fabrics 10 located between the recesses 12, which are arranged offset and regular to each other, can be at least approximately equal in width. The cover fabric 5 of the cover 1 is present as a two- or three-ply (or layer) weft-knitted fabrics with an upper ply 14 forming the outer side 11, an optional middle ply 15 forming the weft-knitted fabric 10 and knitted with the upper ply 14, and an inner or lower ply 16 knitted with the upper ply 14 and / or the optional middle ply 15. The upper layer 14 may comprise a monofilament yarn, such as smooth monofilament yarn, or a multifilament yarn, such as textured twisted multifilament yarn. Similarly, the bottom layer 16 may also comprise a monofilament yarn, such as smooth monofilament yarn, or a multifilament yam, such as textured twisted multifilament yam. Similarly, the middle layer 15 may be formed at least in part of monofilament yarn or multifilament yarn. One or more of the top layer 14, the middle layer 15, and the bottom layer 16 may further include natural fibers and / or be at least partially formed from natural fibers, as described above. The natural fibers may be, for example, animal hair fibers, wool fibers, cotton fibers, hemp fibers, eucalyptus fibers, bamboo fibers, linen fibers, wood fibers, viscose fibers, flax fibers, silk fibers, plant fibers, or a combination thereof. Such natural fibers may be characterized, for example, by increased sustainability, odor neutrality, skin compatibility, durability and / or robustness compared to synthetic fibers. The upper layer 14 further comprises a fine knit structure 17 on the outer side 11, which gives the surface a soft feel. With regard to thickness, the upper layer 14 in the advantageous embodiment shown is dimensioned in such a way that it occupies at least 70% to 80% of the total thickness of the cover fabric 5, in order to utilize the microclimatic advantages of the weft-knitted fabrics 10 to the greatest possible extent. In order to allow the greatest possible air circulation and optimum moisture removal to the outer side 11, the honeycomb-like recesses 12 extend essentially through the thickness of the upper layer 14 and the middle layer 15 to adjacent to the lower layer 16, so that the cover fabric simultaneously exhibits a high degree of flexibility and stretchability in width due to the recesses 12. The elasticity in height results in softness, which can be defined by the filler of the middle layer 14 depending on the desired degree of softness. It is understood that, depending on the application, the cover fabric 5 may be produced using any known spacer knitting process as well as any known finishing process, such as a washing, bleaching and shrinking process following the knitting process. Optionally, the mattress cover 204 may be at least partially coated, rubberized, and / or provided with latex to prevent water penetration. Figures 9a to 9f each show parts of a mattress 202 of a reclining furniture 200 according to exemplary embodiments. Figure 9a shows a top view of a first mattress element 2 of a mattress 202 of a reclining furniture 200. The mattress 202 of Figures 9a to 9f may be combined with any of the preceding aspects of the reclining furniture 200, or individual aspects may be interchanged. Figure 9b schematically shows a cross-sectional view of the first mattress element 2 of Figure 9a, wherein the first mattress element 2 is shown without transverse grooves in Figures 9a and 9b. Figure 9c shows a side view of the first mattress element 2 of Figures 9a and 9b with multiple transverse grooves. Figure 9d shows a top view of a second mattress element 3 according to an embodiment of the disclosure. Figure 9e shows a cross-section of the second mattress element 3 of Figure 9d without transverse grooves. Figure 9f shows a mattress 202 or a combination mattress 202 of the reclining furniture 200 according to an embodiment of the disclosure. The mattress 202 of figure 9f thereby comprises the first mattress element 2 described with reference to figures 9a to 9c and the second mattress element 3 described with reference to figures 9d and 9e. The first mattress element 2 comprises a first outer surface 21 and an oppositely arranged first contact surface 32. The first outer surface 21 is thereby formed as a first lying surface 21 for the user. The second mattress element 3 comprises a second outer surface 31 and an oppositely arranged second contact surface 32. The second outer surface 31 is thereby optionally formed as a second lying surface 31 for the user. The first and second mattress elements 2, 3 are stacked on top of each other such that the first and second contact surfaces 22, 32 are at least partially in contact with each other. For ergonomic and comfortable accommodation of the user, the two mattress elements 2, 3 and / or the mattress 202 and / or the reclining furniture 200 each comprise a plurality of support regions 41, 42, 43, 44, 45. The support areas 41,42, 43, 44, 45 may thereby comprise a head support area 41, a neck support area 42, a shoulder support area 43, a lordosis support area 44 and a pelvis support area 45. The mattress 202 comprises a longitudinal direction x (107 in Figures 1a to 3) or longitudinal axis x that is parallel to a longitudinal side of the mattress 202, a transverse direction z (109 in Figures 1a to 3) or transverse axis z that is parallel to a transverse side of the mattress z, and a vertical axis y that is transverse and / or orthogonal to the longitudinal direction x and the transverse direction z. A length of the mattress 202 of the reclining furniture 200 is dimensioned in the longitudinal direction, a width of the mattress 202 is dimensioned in the transverse direction z, and a thickness or height of the mattress is dimensioned along the vertical axis y. The length of the mattress 202 may be greater than or equal to the width of the mattress 202. The first mattress element 2 and the second mattress element 3 may comprise identical or different heights and / or thicknesses. The x-direction may thereby run parallel to the longitudinal axis 107 of the base element 100 and / or the reclining furniture 200. Alternatively or additionally, the z-direction can run parallel to the transverse axis 109 of the base element 100 and / or the reclining furniture 200. Furthermore, the mattress 202 of the reclining furniture 200 comprises a central transverse axis 5 and / or a central transverse plane 5, which runs parallel to the transverse direction z and is arranged centrally between two ends of the mattress 202 that are opposite one another in the longitudinal direction x. The central transverse axis 5 and / or the central transverse plane 5 separate the first mattress element 2 into a first half 2a and a second half 2b. The central transverse axis 5 and / or the central transverse plane 5 thereby separates the first mattress element 2 into a first half 2a and a second half 2b. Similarly, the central transverse plane 5 and / or the central transverse axis 5 separates the second mattress element 3 into a first half 3a and a second half 3b. Each of the halves 2a, 2b, 3a, 3b of the first and second mattress elements 2, 3 thereby comprises the support areas 41,42, 43, 44, 45. The support areas 41,42, 43, 44, 45 are thereby arranged mirror-symmetrically to the central transverse axis 5. The individual support regions 41, 42, 43, 44, 45 can thereby differ from one another at least in part with regard to a degree of hardness, a hardness, a compression hardness and / or an elasticity. For example, the supporting regions 41,42, 43, 44, 45 can at least partially comprise a profile, profiling and / or structuring that differs from one another, for example in the form of transverse grooves 51,52, 53, 54 formed in the respective supporting regions 41,42, 43, 44, 45. The transverse grooves 51, 52, 53, 54 can thereby be formed in the first and / or second outer surface 21, 31 and extend over the entire width of the mattress 200 in the transverse direction z. In order to adapt the hardness of the individual support areas 41, 42, 43, 44, 45, profiles and / or the transverse grooves 51, 52, 53, 54 in the respective support areas 41,42, 43, 44, 45 may differ from one another in terms of their cross-section, their geometry, their shape, their number, their depth dimensioned along the vertical axis y and / or their thickness or size dimensioned along the longitudinal direction x. As can be seen in Figure 9c, the first mattress element 2 comprises a single first transverse groove 51 in each of the two halves 2a, 2b, which separates the head support area 41 from the neck support area 42. The first transverse groove 51 has a T-shaped cross-section. Furthermore, the first mattress element 2 comprises in each of the two halves 2a, 2b in the shoulder support region 43 a total of five second transverse grooves 52, which each have a round, oval, elliptical and / or drop-shaped cross-section. A geometry, width, dimension, size, thickness and / or a diameter of the five second transverse grooves 52 in the shoulder support regions 43 of the two halves 2a, 2b of the first mattress element 2 are identical. The neck support regions 42 of the first mattress element 2 are separated by one of the second transverse grooves 52 from the shoulder support regions 43 respectively adjacent to the neck support regions 42. Likewise, the lordosis support regions 44 adjacent to the shoulder support regions 43 in the direction of the central transverse axis 5 are separated from the respective shoulder support region 43 by one of the second transverse grooves 52. Furthermore, the lordosis support areas 44 are each separated from the adjacent pelvic support areas 45 by a third transverse groove 53. A total of three third transverse grooves 53 are formed in the two pelvic support regions 45 adjacent to each other at the central transverse axis 5, each of which has a T-shaped and / or triangular cross-section. The three third transverse grooves 53 thereby comprise identical geometries, widths, dimensions, sizes, thicknesses and / or diameters. The middle one of the three third transverse grooves 53 can thereby run in the center transverse plane 5 and define a boundary between the first half 2a and the second half 2b. As shown in Figure 9f, at least one additional transverse groove 54 may be formed in each of the lordosis support regions 44, which may have a circular and / or oval cross-section, for example. As can be seen in Figure 9f, the first mattress element 2 has no profile, profiling and / or structuring on its first contact surface 22. In other words, the first contact surface 22 is configured to be completely flat. Optionally, however, a profile can also be formed on the first contact surface 22 at least in a partial area. Conceivable here are any cross-sectional profiles for transverse grooves, such as round, oval, elliptical, triangular, square, polygonal, trapezoidal or the like, as explained above and below. As can be seen in Figure 9f, the second mattress element 3 comprises a single first transverse groove 61 in each of the two halves 3a, 3b, which separates the head support area 41 from the neck support area 42. The first transverse groove 61 is thereby configured analogously to the first transverse groove 51 of the first mattress element 2 and has a T-shaped cross-section. Furthermore, the second mattress element 3 comprises a total of five second transverse grooves 62 in each of the two halves 3a, 3b in the shoulder support region 43, which each have a round, oval, elliptical and / or drop-shaped cross-section. The second transverse grooves 62 of the second mattress element 3 are thereby configured analogously to the second transverse grooves 52 of the first mattress element, but a width, dimension, size, thickness and / or diameter of the five second transverse grooves 62 in the shoulder support regions 43 of the two halves 3a, 3b of the second mattress element 3 continuously decrease in the direction of the central transverse axis 5. The neck support regions 42 of the second mattress element 3 are separated from the shoulder support regions 43 respectively adjacent to the neck support regions 42 by one of the second transverse grooves 62. Similarly, the lordosis support regions 44 adjacent to the shoulder support regions 43 in the direction of the central transverse axis 5 are separated from the respective shoulder support region 43 by one of the second transverse grooves 62. Furthermore, the lordosis support regions 44 are each separated from the adjacent pelvic support regions 45 by a third transverse groove 63. A total of three third transverse grooves 63 are formed in the two pelvic support regions 45 adjacent to one another at the central transverse axis 5, which are configured analogously to the transverse grooves 53 of the first mattress element 2 and which each have a T-shaped and / or triangular cross section. The three third transverse grooves 63 thereby comprise identical geometries, widths, dimensions, sizes, thicknesses and / or diameters. The middle one of the three third transverse grooves 63 can thereby run in the center transverse plane 5 and define a boundary between the first half 3a and the second half 3b. Furthermore, analogous to the further transverse groove 54 of the first mattress element, at least one further transverse groove 64 may be formed in each of the lordosis support regions 44 of the second mattress element 3, which may, for example, have a round and / or oval cross-section. The transverse grooves 61, 62, 63, 64 of the second mattress element 3 are arranged opposite the transverse grooves 51, 52, 53, 54 of the first mattress element 2 and formed on the second outer surface 32 of the second mattress element 3. Furthermore, the two halves 2a, 2b of the first mattress element 2 and the two halves 3a, 3b of the second mattress element 3 are configured to be completely mirror-symmetrical with respect to the central transverse axis 5 or central transverse plane 5. As shown in Figure 9f, the second mattress element 3 comprises a profile 33 at its second contact surface 32, which profile comprises a plurality of transverse grooves 34. The transverse grooves 34 are exemplarily shown with a rectangular cross-section. Any other cross-sections are conceivable. Also, the profile 33 may be wave-shaped with multiple wave crests and wave troughs. Alternatively or additionally, the profile 33 or another profile may be introduced in the contact surface 22 of the first mattress element 2. Also, profiles and / or transverse grooves may be introduced into both contact surfaces, which may at least partially interlock. Exemplary transverse grooves for the first outer surface, the second outer surface, the first contact surface and / or the second contact surface are shown in the following figures. Figures 10 to 13 each show exemplary transverse grooves of a mattress 202 of a reclining furniture according to an exemplary embodiment. In particular, longitudinal sections through the respective mattress 202 are shown. The mattress 202 of Figure 10 has a total of three parts, comprising three mattress elements 2, 3, 3'. In contrast, the mattresses 202 of Figures 11 to 13 comprise only two mattress elements 2, 3. However, more or fewer mattress elements can be provided as desired. The transverse grooves and / or profiles shown in Figures 10 to 13 are arranged only schematically and exemplarily on the contact or outer surfaces of the mattress elements 2, 3, 3' shown there. However, the transverse grooves and / or profiles may also be arranged on any other surfaces of the mattress 202. In the example in Figure 10, the first mattress element 2 does not comprise a profile or transverse grooves. The second mattress element 3 comprises trapezoidal transverse grooves 500 on the contact surface 33 and rectangular transverse grooves 600 on a side or surface opposite this contact surface 33, which are recessed and / or introduced into the second mattress element 3 at a distance from this surface. A further mattress element 3' without profile forms the further outer surface of the mattress 202. In the example of Figure 11, the first mattress element 2 comprises transverse grooves 500 with a round cross-section on the outer surface 21 and transverse grooves 550 with a rectangular, trapezoidal or triangular cross-section on the contact surface 22. The second mattress element 3 has transverse grooves 600 with a round cross-section only on the outer surface 31 and the contact surface 32 has no profile. In Figure 12, the first mattress element 2 comprises bean-shaped transverse grooves 500 which are introduced into the first mattress element via incisions 501 from the first contact surface 21 such that the transverse grooves 500 are arranged closer to the first outer surface 21 of the first mattress element 2 than to the first contact surface 22 of the first mattress element 2. Similar transverse grooves 600 with incisions 601 are introduced into the second mattress element 3 via the second contact surface 32. In this regard, the transverse grooves 600 are shaped in a boomerang shape, a coat hanger shape, and / or a triangular shape. Further, additional transverse grooves 603 having a circular cross-section are introduced in the second mattress element 3. The second outer surface 31 of the second 5 mattress element 3 has no profile. In the example shown in Figure 13, the first mattress element 2 and the second mattress element 3 have profiles and / or transverse grooves 500, 600 corresponding to one another on their contact surfaces 22, 32, which at least partially interlock in a tooth-like manner. The 10 outer surfaces 21, 31 of the two mattress elements 2, 3 have no profiles. Supplementally, it should be noted that "including" and "comprising" do not exclude other elements, and "one" or "a" do not exclude a plurality. It should further be noted that features described with reference to any of the above exemplary embodiments may also be used in 15 combination with other features of other exemplary embodiments described above. Reference signs in the claims are not to be regarded as limitations.
