[0055] DETAILED DESCRIPTION

[0056] Traditional mattress ticking fabrics used as the fabric covering a mattress typically have little stretch. Thus, when an occupant lies on the mattress, it pulls on the internal mattress components such as the sponge. The border of the covering can be a woven material with little or no stretch properties and may leave unsightly wrinkles after being compressed by the occupant. These two materials (the ticking fabric and the border) are typically sewn together to form the covering of the mattress.

[0057] The subject matter of the present disclosure relates to a mattress covering that reduces permanent deformation and wear of the sponge material of the mattress. While described in the context of sponge material such as a sponge barrel, the subject matter described herein can also be readily applied to mattresses having other materials such as spring barrels and other spring materials. The sponge barrel (or spring barrel) can surround the mattress core. In some embodiments, the sponge barrel (or spring barrel) can surround one or more inflatable air chambers that serve as the mattress core. In some embodiments, the sponge barrel (or spring barrel) can surround one or more spring and / or sponge components that serve as the mattress core. In other embodiments, the sponge barrel (or spring barrel) can be replaced with one or more other mattress components (i.e., sponge, spring, air chamber, and / or other components).

[0058] A mattress cover can have multiple sheets made of materials constructed for specific purposes. For example, a monofilament spacer material can be used for the sleep surface directly beneath where the occupant typically lies. Such material can have multi-directional (i.e., four-way) stretch properties to help the bed's foam and air chambers conform to and support the unique contours of the occupant's body. Such a spacer can also potentially have a positive effect on the occupant's temperature by allowing air flow. A multi-directional or predominantly mono-directional (i.e., two-way) stretch fabric around the perimeter of the sleep surface helps the cover return to shape after the occupant gets out of bed. The perimeter material is attached to a border material that also has multi-directional or predominantly mono-directional (two-way) stretch properties around the bed to help accommodate foam tolerance and recover from bending and compression. A woven material can be positioned beneath and attached to the border material on the sides of the mattress. The woven material can be a non-stretch woven material that has limited stretch and recovery capabilities or no stretch and recovery capabilities and can be suitable for structurally holding the bottom of the mattress. In some embodiments, the mattress cover can include a fabric sheet that includes one, more than one, or all of these materials. In some embodiments, one or more fabric sheets can vary to suit the application.

[0059] Figure 1Is a perspective view of a mattress 10 having an exemplary mattress cover 100 mounted thereon. The mattress 10 includes a mattress top 102, a mattress bottom 104, and a mattress perimeter 106. The mattress cover 100 surrounds the mattress 10 and includes an elastic fabric 108 around the mattress perimeter 106. The elastic fabric 108 is stretchable in a direction parallel to the mattress top 102. The elastic fabric 108 helps to accommodate sponge tolerance and recover from bending and compression. Such stretching and compression may be caused by the general use of the mattress, using an adjustable base with the mattress, transporting the mattress, or any other situation that may cause sponge deformation at the edge of the mattress. An elastic fabric 110 is positioned on the mattress top 102. The elastic fabric 110 configured to be positioned on the mattress top 102 allows the mattress 10 to have sufficient stretchability to fully support the occupant without interference from the mattress cover 100. In some embodiments, the elastic fabric 110 may include a spacer fabric having a monofilament spacer material. The spacer fabric comprises a combination of a textile sheet and distance fibers and has a porous structure that can provide high absorbency to the textile material. The distance fibers may be monofilament polyester fibers having sufficient stiffness to maintain the spacing within the fabric. Thus, the spacer fabric can resist high pressure and can convey fluids and heat, such as sweat and body heat. In such embodiments, the spacer material allows at least a small amount of air flow to help keep the occupant cool and dry. In some embodiments, the mattress cover 100 further includes an elastic fabric 112 positioned between the elastic fabric 108 and the elastic fabric 110. The elastic fabric 112 is stretchable in a direction between an elastic fabric edge 113 and an elastic fabric edge 115. As shown, the elastic fabric 112 is at least partially on the mattress top 102 and partially along the mattress perimeter 106. The elastic fabric 112 helps the mattress cover 100 to recover its shape after the occupant leaves the mattress 10.

[0060] Different sheets of fabric may be attached to each other at one or more seams, such as via sewing / stitching. For example, the elastic fabric 108, the elastic fabric 110, and the elastic fabric 112 may be sewn together to form multiple seams. Seams may also be included by stitching together sheets of the same kind of fabric. For example, the elastic fabric 110 on the mattress top 102 may be formed by two sheets of the elastic fabric 110 sewn together with a seam in the middle, such as Figure 1 as illustrated. Alternatively, the elastic fabric 110 may be formed via a single sheet of material with no seam in the middle of the mattress 100. In additional alternative embodiments, the number and shape of the fabric sheets may also differ from the illustrated examples.

[0061] The mattress cover 100 includes a left side portion 116 and a right side portion 114. In some embodiments, the stretch fabric 112 includes a "waterfall" or wing 117 around the upper corners of the mattress 10, which extends partially over the top 102 of the mattress and partially along the perimeter 106 of the mattress. The stretch fabric 108 has a first portion (not shown) along the left side portion 116 and a second portion 118 along the right side portion 114, the first portion 116 being narrower than the height of the mattress and the second portion 118 being narrower than the height of the mattress. The first portion and the second portion 118 may have the same height (within standard manufacturing tolerances). The stretch fabric 112 extends between the stretch fabric 110 and the edge 115 of the stretch fabric. The stretch fabric 112 is both on the top 102 of the mattress and at least partially along the left side portion 116 and the right side portion 114. The portions of the stretch fabric 108 at the head 122 of the mattress and at the foot 124 of the mattress 10 extend between the top 102 of the mattress and the bottom 104 of the mattress. Each of the first portion and the second portion 118 includes a head section 123 closer to the head 122 of the bed and a foot section 125 closer to the foot 124 of the bed. The height of each of the head section 123 and the foot section 125 is substantially similar (within standard manufacturing tolerances) to the height of the mattress 10.

[0062] The bottom fabric 120 extends from the bottom edge of the stretch fabric 108 to the bottom of the mattress 10. The bottom fabric 120 can be a substantially non-stretch woven material configured to substantially resist or prevent stretching. By resisting stretching, the bottom fabric 120 can help provide rigidity to the bottom portion of the mattress 10, which is beneficial in embodiments of the mattress 10 having an inverted seabed or spring barrel and in other embodiments of the mattress 10 that benefit from a substantially non-stretch woven material. In some embodiments, the bottom fabric 120 can include a substantially non-stretch woven material combined with a laminate material that can provide some rigidity as well as fire-resistant properties.

[0063] In embodiments that do not benefit from the substantially non-stretch woven material used, the bottom fabric 120 can include different materials. For example, in some embodiments, the bottom fabric 120 can include a knitted material or a stretch knitted material. A stretch knitted material can be used in embodiments that benefit from allowing the bottom fabric 120 to stretch slightly or even substantially. In some embodiments, the bottom fabric 120 can be a knitted material with little or no stretch.

[0064] Some or all of stretch fabrics 108, 110, and 112 can be different fabrics with different properties. For example, each of stretch fabrics 108, 110, and 112 can include a knitted material that is configured to stretch and elastically rebound / return to shape, but can have different properties such as knitted thickness, stretch ability, etc. In some embodiments, stretch fabric 108 can include a knitted material with a relatively heavy weight and a relatively limited stretch ability. Stretch fabric 108 can allow some stretching on the sides of mattress 10 while also providing a desired level of stiffness and support to mattress 10. Stretch fabric 110 can include a knitted material with a relatively light weight and a relatively large stretch ability. Stretch fabric 110 can be configured to stretch sufficiently to allow a user lying on mattress 10 to sink into the sponge or other material below stretch fabric 110 without stretch fabric 110 providing an undesired amount of tension. Stretch fabric 110 can include spacer material or can be made without spacer material. Stretch fabric 112 can include a knitted material with a relatively light weight and a relatively large stretch ability. Stretch fabric 112 can be configured to elastically connect stretch fabric 110 on top of mattress 10 to stretch fabric 108 on the sides of mattress 10. Stretch fabric 112 can be configured to stretch much more than both stretch fabrics 110 and 108 such that stretch fabrics 110 and 108 are kept substantially under tension without pulling with an undesirably high amount of tension. In other embodiments, the knitted thickness, stretch ability, and other material properties of stretch fabrics 108, 110, and 112 can vary according to the application.

[0065] In some embodiments, stretch fabrics 108, 110, and 112 can have multi-directional (e.g., four-way) stretch properties. In some such embodiments, one or more of stretch fabrics 108, 110, and 112 can have a primary stretch direction. For example, stretch fabric 108 can stretch primarily in a direction around the perimeter of mattress 10 with less stretching in the vertical direction. Stretch fabric 112 can stretch primarily in a direction extending from stretch fabric 108 to stretch fabric 110 with less stretching in the perpendicular direction. Stretch fabric 110 can stretch equally or substantially equally in each direction.

[0066] In some embodiments, one or more of stretch fabric 108, stretch fabric 110, and stretch fabric 112 may have unidirectional (e.g., bi-directional) stretch properties. For example, in some such embodiments, stretch fabric 108 may stretch only in a direction around the perimeter of mattress 10 and not in a vertical direction. Stretch fabric 112 may stretch only in a direction extending from stretch fabric 108 to stretch fabric 110 and not in a perpendicular direction. Stretch fabric 110 may have multi-directional stretch properties such that it stretches equally or substantially equally in each direction.

[0067] The following paragraphs describe specific embodiments of a mattress cover that may be used with aspects of the present disclosure. The following embodiments are merely examples. The features described herein may be applied to a variety of embodiments. That is, specific features may be mixed between different embodiments. The following embodiments should not be considered a complete list of all possible embodiments of the mattress cover described in the present disclosure, but rather examples of some possible embodiments.

[0068] Figures 2A to 2F is a multi-view and perspective schematic of mattress 20 having an example mattress cover 200 mounted thereon. Figure 2A is a side view of the foot portion 124 of mattress cover 200. Figure 2B is a top view of mattress cover 200. Figure 2C is a side view of the head portion 122 of mattress cover 200. Figure 2D is a bottom view of mattress cover 200. Figure 2E is a side view of the right side portion of mattress cover 200 when mounted around a mattress resting on bed base 150. Figure 2F is a perspective view of mattress cover 200 mounted around mattress 20 resting on adjustable bed base 150. Except for the differences described herein, mattress 20 and mattress cover 200 are substantially similar to mattress 10 and mattress cover 100. In this embodiment, stretch fabric 110 extends across the entire top of the mattress 102, while stretch fabric 112 extends only along the sides of mattress 20, stretching between the edge of stretch fabric 110 and the edge of stretch fabric 108. Refer to Figure 2F , the wings 217 are arranged such that the profile of mattress 20 better conforms to adjustable base 150 than would be the case without wings 217. Wings 217 also reduce permanent wear and deformation due to the use of adjustable base 150.

[0069] Figures 3A to 3F is a multi-view and perspective schematic of mattress 30 having an example mattress cover 300 mounted thereon. Figure 3A is a side view of the foot portion 124 of mattress cover 300.Figure 3B is a top view of the mattress cover 300. Figure 3C is a side view of the head 122 of the mattress cover 300. Figure 3D is a bottom view of the mattress cover 300. Figure 3E is a side view of the right side portion of the mattress cover 300 when installed around the mattress 30 resting on the bed base 150. Figure 3F is a perspective view of the mattress cover 300 installed around the mattress 30 resting on the adjustable bed base 150. Except for the differences described herein, the mattress 30 and the mattress cover 300 are substantially similar to the mattress 10 and the mattress cover 100.

[0070] The mattress 30 has a stretch fabric 112 that is positioned on the top and sides of the mattress 30 and extends from the stretch fabric 110 to the stretch fabric 108. Thus, the stretch fabric 112 somewhat forms a waterfall that covers the sides of the mattress 40 from the top of the mattress 40.

[0071] In this embodiment, the wing portion 317 is of a different shape, which includes a progressive curve along the edge 315 of the stretch fabric 108. Refer Figure 3F , the wing 317 is arranged such that the profile of the mattress 30 better conforms to the adjustable base 150 than it would without the wing 317. The wing 317 also reduces permanent wear and deformation due to the use of the adjustable base 150.

[0072] Figure 4A to FIGS. 4F are multi-view and perspective schematic diagrams of a mattress 40 having an example mattress cover 400 mounted thereon. Figure 4A is a side view of the foot 124 of the mattress cover 400. Figure 4B is a top view of the mattress cover 400. Figure 4C is a side view of the head 122 of the mattress cover 400. Figure 4D is a side view of the right side portion of the mattress cover 400 when installed around the mattress 40 resting on the bed base 150. Except for the differences described herein, the mattress 40 and the mattress cover 400 are substantially similar to the mattress 10 and the mattress cover 100. Like Figures 3A - 3F the example shown in, the mattress 40 has a stretch fabric 112 that is positioned on the top and sides of the mattress 40 and extends from the stretch fabric 110 to the stretch fabric 108. Thus, the stretch fabric 112 somewhat forms a waterfall that covers the sides of the mattress 40 from the top of the mattress 40.

Figure 6A A perspective view of the mattress cover 600. Except for the differences described herein, the mattress 60 and the mattress cover 600 are substantially similar to the mattress 10 and the mattress cover 100. The mattress cover 600 includes a wing section 617 that is shorter in length than Figure 1 the wing shown. In this embodiment, the stretch fabric 110 is mainly positioned on the top of the mattress 60 and also partially extends to the sides of the mattress 60. The stretch fabric 108 can be mainly positioned around the perimeter side of the mattress 60 and also extends to a portion of the top of the mattress 60. The mattress cover 600 includes a dividing section 650 that extends between the head 122 and the foot 124 of the mattress 60. The dividing section 650 can be formed by the stretch fabric 108 and can divide the stretch fabric 110 into a left section 652 and a right section 654.

[0075] In some embodiments of the mattress 60, the stretch fabric 110 and the stretch fabric 108 can each be multi-directionally stretchable and have different material properties suitable for the application. In other embodiments of the mattress 60, the stretch fabric 110 can be multi-directionally stretchable, while the stretch fabric 108 can be replaced by a woven material with little or no ability to stretch elastically.

Figure 7D is an example corner that can be used with the mattress cover 700. In this embodiment, the stretch fabric 110 is extended while the stretch fabric 112 is reduced or eliminated. Such an embodiment reduces the length wings 717 or eliminates them completely. In some embodiments, the stretch fabric 108 can be used only on the head 122 or only on the foot 124.

[0078] Figures 8A to 8B is a side schematic view of the mattresses 80a and 80b, which have example mattress covers 800a and 800b mounted on the mattresses 80a and 80b. Except for the differences described herein, the mattresses 80a and 80b and the mattress covers 800a and 800b are substantially similar to the mattress 10 and the mattress cover 100. Figure 8A shows a ratio to Figure 8BA mattress 80b that is thicker than mattress 80a. Even though mattress 80a is thicker, the stretch fabric 108 remains at the same height for both mattresses 80a and 80b. The illustrated embodiments may include stretch fabric 112, or they may include only stretch fabric 110. The illustrated embodiments have demure wings 817 defined by a gentle curve along the edge 815 of the stretch fabric 108. Compared to Figure 1 the mattress cover 100 shown, the height and length of these wings 817 are smaller.

[0079] Figures 9A to 9B are side schematic views of mattresses 90a and 90b that have example mattress covers 900a and 900b mounted on mattresses 90a and 90b. Except for the differences described herein, mattresses 90a and 90b and mattress covers 900a and 900b are respectively substantially similar to mattresses 80a and 80b and mattress covers 800a and 800b. Figure 9A shows a mattress 90a that is thicker than Figure 9B the mattress 90b shown. Even though mattress 90a is thicker, the stretch fabric 108 remains at the same height in both mattresses 90a and 90b. The illustrated embodiments may include stretch fabric 112, or they may include only stretch fabric 110. The illustrated embodiments have wings 917 defined by a gentle curve along the edge 915 of the fabric. The height and length of these wings 917 are similar to Figure 1 the mattress cover 100 shown.

[0080] Figures 10A to 10B are side schematic views of mattresses 95a and 95b that have example mattress covers 1000a and 1000b mounted on mattresses 95a and 95b. Except for the differences described herein, mattresses 95a and 95b and mattress covers 1000a and 1000b are respectively substantially similar to mattresses 90a and 90b and mattress covers 900a and 900b. Figure 10A shows a mattress 95a that is thicker than Figure 10B the mattress 95b shown. Even though mattress 95a is thicker, for both mattresses 95a and 95b, the stretch fabric 108 remains at the same height. The illustrated embodiments may include stretch fabric 112, or they may include only stretch fabric 110. The illustrated embodiments have wings 1017 defined by the edge 1015 of the stretch fabric 108. The height and length of these wings 1017 are similar to Figure 1The mattress cover 100 shown. Additionally, two mattress covers 1000a and 1000b each include corner protectors 1050a and 1050b respectively. The corner protectors 1050a and 1050b include a third two-way stretch fabric that is configured to stretch in the vertical direction. Due to the use of a thicker mattress 1000a, the height of the corner protector 1050a is increased to match the height of the mattress 95a as compared to the relatively shorter mattress 95b. In the two mattresses 95a and 95b, the stretch fabric 108 remains at the same height.

[0081] Various embodiments of the subject matter have been described. However, it will be understood that various modifications can be made without departing from the spirit and scope of the subject matter described herein.
