DETAILED DESCRIPTION

Referring generally to FIGS. 1 through 8, a mattress assembly 100 is described. The mattress assembly 100 includes a mattress base 102. In some embodiments, the mattress base 102 can be configured as a foam base. For example, the mattress base 102 can include one or more pieces and/or combinations of polyurethane foam, including, but not necessarily limited to: viscoelastic foam, resilient polyurethane foam, high resilience polyether foam, high resilience polyester foam, etc. In some embodiments, the mattress base 102 is formed using polyurethane foam in various forms using variations in formulation to modify its physical properties, such as firmness, density, resilience, airflow, strength, recovery time, etc. Further, a foam mattress base 102 may be reticulated. However, it should be noted that a foam mattress base 102 is provided by way of example and is not meant to limit the present disclosure. In other embodiments, the mattress base 102 can be another base and/or can be a mattress itself, including, but not necessarily limited to: a latex foam mattress, a bladder mattress, an air mattress, an innerspring mattress (e.g., a Bonnell coil mattress, an offset coil mattress, a continuous coil mattress, a wrapped coil mattress, an encased coil mattress, a pocket spring mattress), and so on.

The mattress assembly 100 also includes an encasement 104 to at least partially enclose the mattress base 102. In embodiments of the disclosure, the encasement 104 is formed using upholstery (which may also be referred to as a tick or ticking), which includes a base panel 106 with side panels 108 extendable from the base panel 106. The encasement 104 includes one fastener 110 (e.g., a first zipper and/or another fastener) that extends around the side panels 108 at a first distance 112 (FIG. 8) away from the base panel 106 when the side panels 108 are extended from the base panel 106, and another fastener 114 (e.g., another zipper and and/or another fastener) that extends around the side panels 108 at a second distance 116 (FIG. 8) away from the base panel 106 when the side panels 108 are extended from the base panel 106. In embodiments of the disclosure, the second distance 116 is greater than the first distance 112 (e.g., so the fastener 114 is positioned above the fastener 110).

The encasement 104 can be a natural (e.g., cotton, linen) and/or synthetic (e.g., polyester) textile that is woven and/or knitted. In some embodiments, the encasement 104 can be an encasement containing breathable natural fibers, such as wool, bamboo, silk, etc. and/or synthetic fibers, such as polyester, rayon, etc. In some embodiments, the encasement 104 can be configured to reduce or eliminate a user's exposure to allergens (e.g., dust mites, etc.). In some embodiments, the encasement 104 can be formed using chemically treated fibers and/or inherently fire retardant fibers. For example, the encasement 104 can be a washable material, and the mattress assembly 100 may meet one or more standards for flammability (e.g., open flame) of mattress sets, including, but not necessarily limited to, a 16 CFR 1633 standard. Further, the encasement 104 may be quilted.

In embodiments of the disclosure, the mattress assembly 100 includes an upholstery panel 118 fastenable (e.g., removably securable) to the side panels 108 by the fastener 110. For example, a zipper or another fastener is used to removably secure the panel 118 to the side panels 108 by binding flexible edges of the panel 118 and the side panels 108 together. In this manner, the panel 118, the side panels 108, and the base panel 106 can define an enclosure 120 (FIG. 7) when the panel 118 is fastened to the side panels 108. The enclosure 120 can be used to enclose the mattress base 102.

The mattress assembly 100 also includes another upholstery panel 122 fastenable (e.g., removably securable) to the side panels 108 by the fastener 114. For example, another zipper or another fastener is used to removably secure the panel 122 to the side panels 108 by binding flexible edges of the panel 122 and the side panels 108 together. In this manner, the panel 122, the side panels 108, and the panel 118 can define another enclosure 124 (FIG. 7) when the panel 122 and the panel 118 are fastened to the side panels 108. In embodiments of the disclosure, the enclosure 120 can be used to enclose absorbent foam 126. The absorbent foam 126 may collect moisture (e.g., liquid) that penetrates through the upper panel 122. However, the panel 118 can be constructed from a breathable and/or at least substantially waterproof material, and can prevent the moisture from penetrating through to the mattress base 102. For instance, the panel 118 can be a waterproof, stretchable fabric membrane (e.g., polyethylene material, polytetrafluoroethylene (PTFE) material, etc.). In this manner, the mattress base 102 and the absorbent foam 126 can form a mattress core with the panel 118 forming a breathable waterproof barrier between the absorbent foam 126 and the mattress base 102 within the core.

In some embodiments, the absorbent foam 126 can be machine washable and/or machine dryable. For example, the absorbent foam 126 can be sized appropriately for a residential and/or commercial front-loading washing machine or a similar washing machine (e.g., with limited interior volume). The absorbent foam 126 may also be sized appropriately for a residential and/or commercial dryer or a similar drying machine. In embodiments of the disclosure, the absorbent foam 126 can include one or more (e.g., one (1), two (2), three (3), more than (3), etc.) foam panels 128. One or more of the foam panels 128 can be constructed using a viscoelastic memory foam, which can be reticulated. For instance, in some embodiments, a foam panel 128 includes a foam pad constructed of a viscoelastic or resilient gel foam that has been reticulated to make the viscoelastic or resilient gel foam washable.

In embodiments of the disclosure, the reticulated foam of a foam panel 128 can have between at least approximately eleven (11) and twenty-four (24) cells (holes) per centimeter (e.g., 11.0 cells per centimeter, 11.5 cells per centimeter, 12.0 cells per centimeter, 12.5 cells per centimeter, 13.0 cells per centimeter, 13.5 cells per centimeter, 14.0 cells per centimeter, 14.5 cells per centimeter, 15.0 cells per centimeter, 15.5 cells per centimeter, 16.0 cells per centimeter, 16.5 cells per centimeter, 17.0 cells per centimeter, 17.5 cells per centimeter, 18.0 cells per centimeter, 18.5 cells per centimeter, 19.0 cells per centimeter, 19.5 cells per centimeter, 20.0 cells per centimeter, 20.5 cells per centimeter, 21.0 cells per centimeter, 21.5 cells per centimeter, 22.0 cells per centimeter, 22.5 cells per centimeter, 23.0 cells per centimeter, 23.5 cells per centimeter, 24.0 cells per centimeter) or between at least approximately thirty (30) and sixty (60) cells per inch (e.g., 30 cells per inch, 31 cells per inch, 32 cells per inch, 33 cells per inch, 34 cells per inch, 35 cells per inch, 36 cells per inch, 37 cells per inch, 38 cells per inch, 39 cells per inch, 40 cells per inch, 41 cells per inch, 42 cells per inch, 43 cells per inch, 44 cells per inch, 45 cells per inch, 46 cells per inch, 47 cells per inch, 48 cells per inch, 49 cells per inch, 50 cells per inch, 51 cells per inch, 52 cells per inch, 53 cells per inch, 54 cells per inch, 55 cells per inch, 56 cells per inch, 57 cells per inch, 58 cells per inch, 59 cells per inch, 60 cells per inch, etc.). However, it should be noted that this range is provided by way of example and is not meant to limit the present disclosure. In other embodiments, a foam panel 128 can have less than eleven (11) cells per centimeter, more than twenty-four (24) cells per centimeter, and so forth.

A foam panel 128 can also include a substrate (e.g., a fabric cover) attached to the foam material (e.g., to hold the foam material together during washing). In some embodiments, an overlock stitch (e.g., formed using a serging machine) can be used to fasten a fabric cover to a foam panel 128, which may also include a welt. In other embodiments, a foam panel 128 can include foam flame-laminated to fabric. However, these examples are not meant to limit the present disclosure. In other embodiments, the foam panel 128 can include foam material glued to fabric, covered by fabric, quilted to fabric, and so forth. It should be noted that the fabric coating the foam of a foam panel 128 can be perforated (e.g., in the manner of a mesh) to allow moisture to penetrate into the foam. In this manner, a foam panel 128 can be removed, washed (e.g., machine washed), dried (e.g., machine dried), and reinserted into a mattress assembly 100.

In some embodiments, the foam panels 128 can be attached to a panel 118, a panel 122, and/or to one another (e.g., to hold the foam panels 128 in place with respect to the mattress base 102). For example, in some embodiments, the foam panels 128 can be attached to a panel 118, a panel 122, and/or to one another using one or more fasteners, including, but not necessarily limited to: hook-and-loop fasteners (e.g., VELCRO hook-and-loop fasteners), button fasteners, snap fasteners, clip fasteners, and so forth.

In some embodiments, the foam panels 128 can be arranged one on top of another (e.g., in two (2) layers, each at least approximately three and eight-tenths centimeters (3.8 cm) or one and one-half inches (1.5″) thick as shown in the accompanying figures). However, this configuration is provided by way of example only and is not meant to limit the present disclosure. In other embodiments, foam panels may be arranged side-by-side. Further, the absorbent foam 126 may be a single foam panel 128 (e.g., at least approximately seven and six-tenths centimeters (7.6 cm) or three inches (3″) thick). In some embodiments, foam panels may be arranged side-by-side and on top of one another. In any of these configurations, one or more fasteners can be used to connect the foam panels to a panel 118, a panel 122, and/or to one another. For example, in a side-by-side configuration, a flap may be included at an edge of a foam panel that has a hook fastener pattern, while a corresponding area of an adjacent foam panel can include a loop fastener pattern designed to interface with the hook fastener pattern.

In some embodiments, a mattress assembly can be configured to include one or more mattress inserts. For instance, a mattress assembly includes a mattress that defines a recess for receiving one or more mattress inserts. In some embodiments, a mattress base includes a dense foam base material with a casing around the base material. In embodiments of the disclosure, the casing extends above a top surface of the base material to form a recess for receiving one or more mattress inserts. A mattress insert is configured to be inserted into the recess formed in the mattress and can be constructed of foam material (e.g., as previously described).

In some embodiments, the mattress inserts can be attached to the mattress (e.g., to hold the mattress inserts in place with respect to the mattress). For example, in some embodiments, the mattress inserts can be attached to the mattress using one or more fasteners, including, but not necessarily limited to: hook-and-loop fasteners (e.g., VELCRO hook-and-loop fasteners), button fasteners, snap fasteners, clip fasteners, and so forth. Further, a mattress assembly can include a removable mattress cover, including, but not necessarily limited to, a washable material that meets a 16 CFR 1633 standard, as a machine-washable mattress cover. In some embodiments, the mattress assembly can include fabric material constructed from a waterproof fabric membrane (e.g., polyethylene material). The waterproof material can be positioned between, for example, a mattress insert and the base material of the mattress.

By way of example, the following table provides sizes and numbers for various mattress inserts. However, these sizes and numbers are not meant to limit the present disclosure. Mattress insert sizes may be configured for machine washing in an eighty-eight one-hundredths (0.088) cubic meter or three and one-tenth (3.1) cubic feet or larger front loading washing machine. Thus, other various sizes and/or numbers of inserts can be used in accordance with the present disclosure.

It is contemplated that the foam (e.g., mattress) inserts can be utilized within a bedding for animals, such as dogs, cats, and the like.

The mattress insert can be made in a variety of different firmness levels. This allows for different firmness configurations within the mattress. For example, in the case of the King size mattress, the mattress inserts may be configured with firm inserts on one side of the mattress and soft inserts on the other side of the mattress.

In some embodiments, the washable mattress may comprise a reticulated machine washable memory foam mattress. For example, the removable top cover of the mattress may be composed of a two and one-half centimeter (2.5 cm) or one-inch (1″) reticulated memory gel foam that has been strengthened to hold up when machine washed and/or machine dried. This foam has been formulated so that it can be flame laminated to fabric. For instance, the foam is fastened by serging or flame laminated to a machine washable/dryable cotton fabric panel that may prevent the foam from shifting in the cover when washed and dried. The reticulation process eliminates the windows and reinforces the microscopic struts which form the high strength memory foam cells. For example, reticulation opens the structure of the foam so that water may easily flow through the foam greatly enhancing its “washability” and can enhance air flow in the foam providing cooling/drying benefits. Additionally, reticulation does not substantially change the resilience and/or viscoelastic properties of the foam.

In some embodiments, the washable mattress comprises a microencapsulated phase change material. For instance, a second eight and one-quarter centimeter (8.25 cm) or three and one-quarter inch (3.25″) removable layer of memory foam can be coated with a layer of phase change gel material. This phase change gel material may be similar to the phase change gel material described in International Patent Application Number WO2011/107849, which is incorporated herein by reference. The phase change gel comprises extremely small capsules (typically five (5) to forty (40) microns for use in foam production) that permanently contain phase change materials (PCMs) and allow the PCM to absorb thermal energy when exposed to heat. Test results demonstrate the ability of Phase Change Gel to provide significant cooling benefits when applied to flexible polyurethane foam.

The phase change gel comprises non-porous characteristics and this coating may provide a waterproof barrier between the top washable cover and the underlying layers of foam. Additionally, the second eight and one-quarter centimeter (8.25 cm) or three and one-quarter inch (3.25″) phase change gel/memory foam layer is configured to be removable so that the foam can be wiped down in place or removed and sprayed down. The second layer can be T-shaped to provide a flat uninterrupted sleeping surface on top with recessed foam underneath that substantially locks into the tub construction of the mattress.

Although the subject matter has been described in language specific to structural features and/or process operations, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.
