DETAILED DESCRIPTION

Traditional mattress ticking that is used as fabric that covers a mattress often has very little stretch. Consequently, it pulls on interior mattress components (such as foam) when an occupant lays on the mattress. A border of the cover can be a woven material with little or no stretch properties and can retain unsightly wrinkles after it is compressed by the occupant. These two materials (ticking and border) are often sewn together to form a cover for the mattress.

The subject matter of this disclosure relates to a mattress cover that reduces permanent deformation and wear of foam material of a mattress. While described in the context of foam material (such as a foam tub), the subject matter described herein can easily be applied to mattresses having other materials (such as spring tubs and other spring material) as well. The foam tub (or spring tub) can surround a mattress core. In some embodiments, the foam tub (or spring tub) can surround one or more inflatable air chambers used as the mattress core. In some embodiments, the foam tub (or spring tub) can surround one or more spring and/or foam components used as the mattress core. In other embodiments, the foam tub (or spring tub) can be replaced with one or more other mattress components (i.e. foam, springs, air chambers, and/or other components).

A mattress cover can have multiple panels made of materials that are configured to function for a certain purpose. For example, a monofilament spacer material can be used for the sleep surface directly underneath where the occupant would typically lay. This material can have multidirectional (i.e. four-way) stretch properties to help the foam and air chamber of the bed to conform to and supports the unique contours of the occupant's body. Such a spacer also could potentially have a positive impact on the occupant's temperature by allowing for airflow. A multidirectional 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 the bed. The perimeter material attaches to a border material that also has multidirectional or predominantly mono-directional (two-way) stretch properties around the bed to help accommodate foam tolerance and recover from flexing and compression. A woven material can be positioned below and attached to the border material on the sides of the mattress. The woven material can be non-stretch woven material that has limited or no capacity for stretching and recovery and can be suitable for structurally retaining a bottom of the mattress. In some embodiments, a mattress cover can include panels of fabric including one, more than one, or all of these materials. In some embodiments, one or more panels of fabric can be different as suitable for the application.

FIG. 1 is a perspective view of a mattress 10 having an example mattress cover 100 installed over the mattress 10. 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 a stretch fabric 108 around the mattress perimeter 106. The stretch fabric 108 is stretchable in a direction parallel to the mattress top 102. The stretch fabric 108 helps accommodate foam tolerance and recovery from flexing and compression. Such stretching and compression can be caused by general use of the mattress, using an adjustable base with the mattress, shipping the mattress, or any other scenarios that can cause foam deformation to the mattress edges. A stretch fabric 110 is positioned on the mattress top 102. The stretch fabric 110, configured to be positioned on the mattress top 102, allows for sufficient stretch for the mattress 10 to fully support an occupant without interference from the mattress cover 100. In some implementations, the stretch fabric 110 can include a spacer fabric with a monofilament spacer material. Spacer fabrics contain a combination of textile sheets and distance fibers, with a porous structure that can offer high absorption capacities for textile materials. The distance fibers can be monofilament polyester fibers with a sufficient stiffness to maintain spacing within the fabric. As such, spacer fabrics can resist high pressure and can transport fluid and heat, for example, sweat and body heat. In such an implementation, the spacer material allows for at least a small amount of airflow to help keep the occupant cool and dry. In some implementations, the mattress cover 100 also includes a stretch fabric 112 positioned between the stretch fabric 108 and the stretch fabric 110. The stretch fabric 112 is stretchable in a direction between a stretch fabric edge 113 and a stretch fabric edge 115. As illustrated, the stretch fabric 112 is at least partially on the mattress top 102 and partially along the mattress perimeter 106. The stretch fabric 112 helps the mattress cover 100 return to shape after an occupant leaves the mattress 10.

Different panels of fabric can be attached to each other at one or more seams, such as via sewing/stitching. For example, the stretch fabric 108, the stretch fabric 110, the stretch fabric 112 can be sewn together forming multiple seams. Seams can also be included by stitching together panels of the same kind of fabric. For example, the stretch fabric 110 on the mattress top 102 can be formed of two panels of the stretch fabric 110 sewn together with a seam down the middle, such as illustrated in FIG. 1. Alternatively, the stretch fabric 110 can be formed via a single panel of material, with no seam down the middle of the mattress 100. In further alternative embodiments, the number and shape of fabric panels can be further varied from the illustrated examples.

The mattress cover 100 includes a left side 116 and a right side 114. In some implementations, the stretch fabric 112 includes a “waterfall” or wing 117 around an upper corner of the mattress 10, stretching partially on the mattress top 102 and partially along the mattress perimeter 106. The stretch fabric 108 has a first portion (not shown) along the left side 116 that is narrower than a height of the mattress and a second portion 118 along the right side 114 that is narrower than the height of the mattress. The first portion and the second portion 118 can be the same height (within standard manufacturing tolerances). The stretch fabric 112 extends between the stretch fabric 110 to the stretch fabric edge 115. The stretch fabric 112 is both on the mattress top 102 and at least partially along the left side 116 and the right side 114. A portion of the stretch fabric 108 at a head 122 of the mattress and at a foot 124 of the mattress 10 extends between the mattress top 102 and a mattress bottom 104. The first portion and the second portion 118 each include a head section 123 nearer a head 122 of the bed and a foot section 125 nearer the foot 124 of the bed. Each of the head sections 123 and the foot sections 125 have a height substantially similar (within standard manufacturing tolerances) to a height of the mattress 10.

A bottom fabric 120 extends from a bottom edge of the stretch fabric 108 to a bottom of the mattress 10. The bottom fabric 120 can be a substantially non-stretch woven material configured to substantially resist stretching or to prevent stretching. By resisting stretching, the bottom fabric 120 can help provide rigidity to a bottom portion of the mattress 10, which can be beneficial in embodiments of the mattress 10 having an upside-down foam or spring tub and in other embodiments of the mattress 10 that benefit from substantially non-stretch woven material. In some embodiments, the bottom fabric 120 can include the substantially non-stretch woven material in combination with a laminate material that can provide some rigidity as well as fire resistance properties.

In embodiments that do not benefit from a substantially non-stretch woven material being used, the bottom fabric 120 can include a different material. For example, in some embodiments the bottom fabric 120 can include a knit material or a stretch knit material. A stretch knit material can be used in embodiments that benefit from having the bottom fabric 120 being stretchable by a small amount or even a large amount. In some embodiments, the bottom fabric 120 can be a knit material with little or no ability to stretch.

Some or all of the stretch fabric 108, the stretch fabric 110, and the stretch fabric 112 can be different fabrics having different properties. For example, the stretch fabric 108, the stretch fabric 110, and the stretch fabric 112 can each include knit materials that are configured to stretch and resiliently rebound/recover to shape, but can have different properties such as knit thickness, capacity for stretching, etc. In some embodiments, the stretch fabric 108 can include a knit material with a relatively thick weight knit and a relatively limited capacity for stretching. The stretch fabric 108 can allow for some stretching on the sides of the mattress 10 while also providing a desirable level of stiffness and support for the mattress 10. The stretch fabric 110 can include a knit material with a relatively thin weight knit and a relatively large capacity for stretching. The stretch fabric 110 can be configured to stretch enough to allow a user lying on the mattress 10 to sink into the foam or other material under the stretch fabric 110 without the stretch fabric 110 providing an undesirable amount of tension. The stretch fabric 110 can include a spacer material, or can be made without a spacer material. The stretch fabric 112 can include a knit material with a relatively thin weight knit and a relatively large capacity for stretching. The stretch fabric 112 can be configured to resiliently connect the stretch fabric 110 on top of the mattress 10 to the stretch fabric 108 on the sides of the mattress 10. The stretch fabric 112 can be configured to stretch more than both of the stretch fabrics 110 and 108 so as to substantially keep the stretch fabrics 110 and 108 under tension without pulling with an undesirably high amount of tension. In other embodiments, the knit thickness, capacity for stretching, and other material properties of the stretch fabric 108, the stretch fabric 110, and the stretch fabric 112 can be varied as suitable for the application.

In some embodiments, the stretch fabric 108, the stretch fabric 110, and the stretch fabric 112 can have multidirectional (e.g. four-way) stretch properties. In some of such embodiments, one or more of the stretch fabric 108, the stretch fabric 110, and the stretch fabric 112 can have a dominant stretch direction. For example, the stretch fabric 108 can stretch predominantly in a direction around a perimeter of the mattress 10, with less stretching in a vertical direction. The stretch fabric 112 can stretch predominantly in a direction extending from the stretch fabric 108 to the stretch fabric 110, with less stretching in a perpendicular direction. The stretch fabric 110 can stretch either equally or substantially equally in each direction.

In some embodiments, one or more of the stretch fabric 108, the stretch fabric 110, and the stretch fabric 112 can have mono-directional (e.g. two-way) stretch properties. For example, in some of such embodiments, the stretch fabric 108 can stretch only in a direction around a perimeter of the mattress 10, with no stretching in a vertical direction. The stretch fabric 112 can stretch only in a direction extending from the stretch fabric 108 to the stretch fabric 110, with no stretching in a perpendicular direction. The stretch fabric 110 can have multi directional stretch properties so as to stretch either equally or substantially equally in each direction.

The following paragraphs describe specific implementations of mattress covers that can be used with aspects of this disclosure. The following implementations are only examples. The features described herein can be applied to a number of implementations. That is, specific features can be mixed between different implementations. The following implementations should not be considered a complete list of all possible implementations of the mattress covers described by this disclosure, but rather, are examples of some possible embodiments.

FIGS. 2A-2F are multi-view and perspective schematic drawings of a mattress 20 having an example mattress cover 200 installed over the mattress 20. FIG. 2A is a side view of a foot 124 of the mattress cover 200. FIG. 2B is a top view of the mattress cover 200. FIG. 2C is a side view of a head 122 of the mattress cover 200.

The mattress 30 and mattress cover 300 are substantially similar to the mattress 10 and mattress cover 100 with the exception of differences described herein.

The mattress 30 has the stretch fabric 112 positioned on both the top and the sides of the mattress 30, extending from the stretch fabric 110 to the stretch fabric 108. Accordingly, the stretch fabric 112 forms somewhat of a waterfall from the top of the mattress 40 over the sides of the mattress 40.

In this implementation, the wing portion 317 is a different shape that includes a gradual curve along an edge 315 of the stretch fabric 108. Referring to FIG. 3F, the wings 317 are arranged such that the mattress 30 contours to an adjustable foundation 150 better than if the wings 317 were not present. The wings 317 also reduce permanent wear and deformation from the use of an adjustable foundation 150.

FIGS. 4A-4F are multi-view and perspective schematic drawings of a mattress 40 having an example mattress cover 400 installed over the mattress 40. FIG. 4A is a side view of a foot 124 of the mattress cover 400. FIG. 4B is a top view of the mattress cover 400. FIG. 4C is a side view of a head 122 of the mattress cover 400. FIG. 4D is a side view of the right side of the mattress cover 400 while installed around the mattress 40 resting upon a bed foundation 150.

Like the example shown in FIGS. 3A-3F, the mattress 40 has the stretch fabric 112 positioned on both the top and the sides of the mattress 40, extending from the stretch fabric 110 to the stretch fabric 108. Accordingly, the stretch fabric 112 forms somewhat of a waterfall from the top of the mattress 40 over the sides of the mattress 40.

FIGS. 5A-5D are perspective schematic drawings of a mattress 50 having an example mattress cover 500 installed over the mattress 50 and various corner configurations for the example mattress 50. FIG. 5A is a perspective view of a mattress cover 500. The mattress 50 and mattress cover 500 are substantially similar to the mattress 10 and mattress cover 100 with the exception of differences described herein. The mattress cover 500 includes a wing section 517 that extends around the left side 116 of the mattress 50, the foot 124 of the mattress 50, and the right side 114 of the mattress 50. The stretch fabric 108 includes a narrow split 502 along each side near (i.e. within two to three feet of) the head 122 of the mattress 50. FIG. 5B is an example corner that can be used with mattress cover 500. In this implementation, the narrow split 502 is nearer the head 122 of the mattress. FIG. 5C is an example corner that can be used with mattress cover 500. In this implementation, the stretch fabric 108 is a uniform height around the mattress perimeter 106 of the mattress, eliminating the wings 517. FIG. 5D is an example corner that can be used with mattress cover 500. In this implementation, the stretch fabric 108 is limited to a portion along the side near the head of the mattress 50 and along the head of the mattress 50. Such an implementation increases the length and height of the wings 517. In some implementations, the stretch fabric 108 can be used on the foot 124 as well. In some implementations, the stretch fabric 112 can be limited to the mattress perimeter 106 or eliminated entirely.

FIGS. 6A-6D are perspective schematic drawings of a mattress 60 having an example mattress cover 600 installed over the mattress 60 and various corner configurations for the example mattress 60. FIG. 6A is a perspective view of the mattress cover 600. The mattress 60 and mattress cover 600 are substantially similar to the mattress 10 and mattress cover 100 with the exception of differences described herein. The mattress cover 600 includes a wing section 617 that is shorter in length than that illustrated in FIG. 1. In this implementation, the stretch fabric 110 is positioned primarily on top of the mattress 60 and also extends partially over the side of the mattress 60. The stretch fabric 108 can be positioned primarily around the perimeter sides of the mattress 60 and also extend on to parts of the top of the mattress 60. The mattress cover 600 includes a divider section 650 that extends between the head 122 and the foot 124 of the mattress 60. The divider section 650 can be formed of the stretch fabric 108 and can separate the stretch fabric 110 into a left section 652 and a right section 654.

In some embodiments of the mattress 60, the stretch fabric 110 and the stretch fabric 108 can each stretch multidirectionally and have different material properties suitable for the application. In other embodiments of the mattress 60, the stretch fabric 110 can stretch multidirectionally and the stretch fabric 108 can be replaced with a woven material with little or no capacity for resiliently stretching.

FIG. 6B-6D are example corners that can be used with mattress cover 600.

FIGS. 7A-7D are perspective schematic drawings of a mattress 60 having an example mattress cover 700 installed over the mattress 70 and various corner configurations for the example mattress 70. FIG. 7A is a perspective view of the mattress cover 700. The mattress 70 and the mattress cover 700 are substantially similar to the mattress 10 and mattress cover 100 with the exception of differences described herein. The mattress cover 700 includes a divider section 750 that extends between the head 122 and the foot 124 of the mattress 70. The divider section 750 separates the stretch fabric 110 into a left section 752 and a right section 754. FIG. 7B is an example corner that can be used with mattress cover 700. FIG. 7C is an example corner that can be used with mattress cover 700. The mattress 70 shown in FIG. 7B is thicker than the mattress 70 shown in FIG. 7C. The stretch fabric 108 extends between a mattress bottom 104 and mattress top 102 of the mattress 70 near the head 122 and foot 124 of the mattress 70 in both implementations. FIG. 7D is an example corner that can be used with the mattress cover 700. In this implementation, the stretch fabric 110 is extended while the stretch fabric 112 is reduced or eliminated. Such an implementation decreases the length wings 717 or eliminates them entirely. In some implementations, the stretch fabric 108 can be used solely on the head 122 or solely on the foot 124.

FIGS. 8A-8B are side-view schematic drawings of mattresses 80a and 80b having example mattress covers 800a and 800b installed over the mattresses 80a and 80b.

FIG. 8A shows a thicker mattress 80a than the mattress 80b of FIG. 8B. The stretch fabric 108 remains at the same height for both mattresses 80a and 80b, even though the mattress 80a is thicker. The illustrated implementations can include the stretch fabric 112, or they can include only the stretch fabric 110. The illustrated implementations have demure wings 817 defined by a mild curve along the edge 815 of the stretch fabric 108. These wings 817 are smaller in height and length in comparison to the mattress cover 100 illustrated in FIG. 1.

FIGS. 9A-9B are side-view schematic drawings of mattresses 90a and 90b having example mattress covers 900a and 900b installed over the mattresses 90a and 90b. The mattresses, 90a and 90b, and mattress covers, 900a and 900b, are substantially similar to the mattresses, 80a and 80b, and mattress covers, 800a and 800b, respectively, with the exception of differences described herein. FIG. 9A shows a thicker mattress 90a than the mattress 90b shown in FIG. 9B. The stretch fabric 108 remains at the same height in both mattresses 90a and 90b, even though the mattress 90a is thicker. The illustrated implementations can include the stretch fabric 112, or they can include only the stretch fabric 110. The illustrated implementations have wings 917 defined by a mild curve along the edge 915 of the fabric. These wings 917 are similar in height and length to the mattress cover 100 illustrated in FIG. 1.

FIGS. 10A-10B are side-view schematic drawings of mattresses 95a and 95b having example mattress covers 1000a and 1000b installed over the mattresses 95a and 95b. The mattresses, 95a and 95b, and mattress covers, 1000a and 1000b, are substantially similar to the mattresses, 90a and 90b, and mattress covers, 900a and 900b, respectively, with the exception of differences described herein. FIG. 10A shows a thicker mattress 95a than the mattress 95b shown in FIG. 10B. The stretch fabric 108 remains at the same height for both of the mattresses 95a and 95b, even with a thicker mattress 95a. The illustrated implementations can include the stretch fabric 112, or they can include only the stretch fabric 110. The illustrated implementations have wings 1017 defined by the edge 1015 of the stretch fabric 108. These wings 1017 are similar in height and length to the mattress cover 100 illustrated in FIG. 1. In addition, both the mattress covers 1000a and 1000b 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. As a thicker mattress 1000a is used, the height of the corner protector 1050a increases to match the height of the mattress 95a as compared to the relatively shorter mattress 95b. The stretch fabric 108 is kept at the same height in both of the mattresses 95a and 95b.

A number of implementations of the subject matter have been described.

Nevertheless, it will be understood that various modifications can be made without departing from the spirit and scope of the subject matter described herein. For example, in some implementations, corner protectors can be added, even if not specifically described as such. Alternatively or in addition, splits in the fabric along the perimeter can be included in any of the described implementations. Alternatively or in addition, each of the described examples can one or more fabric panels that use multidirectional stretch knits, multidirectional stretch knits with a dominant stretch direction, mono-directional stretch knits, and/or woven materials such as non-stretch woven materials. Moreover, in some implementations, various components of the mattress cover can be shaped differently than as illustrated. Additionally, different aspects of the different implementations of foundations, mattresses, and other bed system components described above can be combined with other aspects as suitable for the application. Accordingly, other implementations are within the scope of the following claims.
