Multi-layer cushion supports are described which may generally comprise a first support having a first contact surface for contacting a portion of a body and a second surface opposite to the first surface, the first support defining a central chamber and a peripheral chamber surrounding the central chamber, wherein the first support is filled with a first gas or liquid and a second support attached to the first support along the first contact surface. The second support may be filled with a second gas or liquid which is relatively more viscous than the first gas or liquid. In particular, the first support may be filled with a volume of air and the second support may be filled with oil which is less than the volume of air.

The present invention provides systems, methods, and articles for temperature conditioning a surface. An article is formed from a first layer having a plurality of openings and a second layer having a corresponding plurality of openings. At least one interior chamber constructed and configured to retain a fluid without leaking is defined between an interior surface of the first layer and an interior surface of the second layer. At least one flexible fluid supply line delivers the fluid to the at least one interior chamber. At least one flexible fluid return line removes the fluid from the at least one interior chamber. At least one control unit that is operable to selectively cool or heat the fluid is attached to the at least one flexible fluid supply line and the at least one flexible fluid return line.

The present disclosure relates to medical pads and methods of manufacturing medical pads.

A spinal immobilization device including a base member and a spinal support member configured to overlay the base member. The base member includes an elongate board having a curvate top surface, and a channel defined within the top surface. The spinal support member may include a bladder, a fluid housed within the bladder, a plurality of fluid absorbing members within the bladder, and a breakable barrier separating the fluid and the plurality of fluid absorbing members from mixing. The channel defines an impression within the top surface that matches a shape of a portion of the bladder.

The methods and structures disclosed herein may be used to make sleep products having foam substrates and gel layers such as mattresses, mattress toppers and pillows. The gel layers may have cooling properties and may include phase change materials. The foam substrates may also be treated with phase change materials.

Shear-reduction cushioning devices are provided for the prevention of shear related wounds. Cushioning devices include upper and lower cushioning layers that contact each other through at least one internal shear reduction layer provided between the cushioning layers and extending over a shear reduction region, such that dynamic relative translation of the two cushioning layers is permitted within the shear reduction region while absorbing friction and shear internally. The interface between the cushioning layers (where the shear reduction layer is provided) may be angled relative to an external surface of the cushioning device. The cushioning layers may be attached or attachable to one another beyond the shear reduction region, to limit an amount of relative translation of the cushioning layers and to re-center or reset the cushioning layers after use.

The present invention discloses a modular mattress that allows for customization of the overall firmness, thickness, and breathability of the mattress along with providing an optimal comfort to users. The modular mattresses comprise at least three modules of mattresses with different thicknesses include a lower, a middle, and a top mattress. The lower and middle mattresses are made of a material includes a polyurethane foam and the top mattress is made of a material made of a gel-infused viscoelastic memory foam. The mattresses are covered by a microfiber fabric cover. The cover of each mattress further comprises a hook and loop fabrics and rubberization. The hook fabric of the cover of the lower mattress mates with a center section of loop fabric sewn into a lower surface of the middle mattress to prevent movements during use. The modular mattresses provide optimum comfort to the user while sleeping and resting.

A single-person chair includes a proximal end, a distal end, and a generally convex central portion extending between the proximal end and the distal end. The central portion extends upwardly, forming a first pool between the proximal end and the central portion and a second pool between the distal end and the central portion. A backrest is releasably connectable to the proximal end. A longitudinal centerline extends between the proximal end and the distal end. A first sidewall extends between the proximal end and the distal end on a first side of the longitudinal centerline and a second sidewall extends between the proximal end and the distal end on a second side of the longitudinal centerline. A liquid can be contained within the chair between the proximal end, the distal end, the first sidewall, and the second sidewall.

A waterbed system for placement on a ground surface can comprise one or more of the following components: a waterbed mattress, a foam structure around the periphery of the mattress, a platform below the mattress and the foam periphery for supporting the waterbed mattress and the foam structure, a foundation coupled to and extending downwardly from the platform, preferably a single, fire resistant polyester fiber baffle disposed within the waterbed mattress, a cover over the top surface of the mattress and around the outer surface of the foam structure, a water proof liner below the bottom surface of the mattress, a water bed heater under the liner between the liner and the upper surface of the platform, a layer of fiberglass insulation attached to the lower surface of the platform, and an accessory storage container coupled to the foundation.
