    Abstract: An adaptable surface system including a plurality of individually adjustable surface units and a plurality of pressure sensors. Each pressure sensor corresponds to one of the adjustable subsurface units and is positioned to measure an amount of pressure exerted upon the subsurface unit. The system also includes a controller that receives a first pressure value from a pressure sensor, compares the value to a threshold, and adjusts the height of the first subsurface unit based on the comparison. The controller also receives a second pressure value from a second pressure sensor, compares the second pressure value to the threshold, and adjusts the height of a second subsurface unit based on the comparison.

Flaps which are unitary with the central section extend from the side edges of the central section a distance beyond the side edges of the support surface. The flaps are thinner than the central section so as to depend from the central section and lie alongside the patient-supporting surface. The central section and the flaps are formed simultaneously by compressing a block of cushioning material in such manner that the central section forms a pad or cushion unitarily joined at its opposite sides to the flaps. During the compression of the block to form the central pad and the flaps the external surfaces of the pad and flaps are heated to an extent sufficient to enable the surfaces of the pad and flaps to form a smooth, moisture proof skin.

  • Publication number: 20090083908
    Abstract: Hygienic, antibacterial, and anti-allergenic pillows or pillow encasings with a covering are disclosed. The covering comprises a fabric coated with a monolithic coating and a filter. The monolithic coating prevents moisture from entering the pillow and allergens from leaving the pillow or pillow encasing. The filter is operative to allow air to egress and ingress the pillow covering.

  • Patent number: 7509700
    Abstract: An institutional mattress includes a resilient core and a mattress covering sealing the core. The mattress covering has a ticking with a base fabric made of yarns with a denier value of at least 500 and has a thread count of at least 18 threads per inch in both warp and fill. The ticking is bonded to a fluid proof material having an anti-microbial agent. The core may be fire resistant polymeric foam and the ticking base fabric may be 1050 denier “ballistic” nylon. The ticking base fabric may be coated with urethane having at least one of a flame retardant and an anti-microbial, and then laminated with a polyurethane film. Alternatively, the ticking base fabric may be treated with a flame retardant covered with a fluid proof material. The mattress covering may be sealed around the core with stitching.

  • Publication number: 20080216247
    Abstract: A non-toxic mattress and method of constructing the mattress having a reduced toxicity has an outer layer of a material selected from the group comprising polyethylene and polylactic acid film. Also, a mattress cover for covering the outer layer of the mattress can also be constructed from a material selected from the same group of materials. The polyethylene and polylactic acid films are non-toxic materials which reduce adverse human allergenic reactions or exposure to potentially harmful chemicals used in the mattress construction.

  • Patent number: 7370380
    Abstract: A mattress is constructed from a mattress body having an upper and a lower deck, which is preferably pervious to moisture and air. A removable panel, which includes a top layer of breathable fabric, a bottom layer of a fabric that forms a moisture barrier, and a batting layer, is placed on at least the upper deck of the mattress body. The removable panel is removably attached along the perimeter of the deck or decks by a fastener, such as a zipper. The panel can be removed from the deck for cleaning and folded and secured by the fastener in an inverted configuration, with the top layer facing outward.
