    Abstract: A method of making foam imparts antimicrobial and antiodorant qualities to the foam. Green tea powder is added to the polyol raw materials for making memory foam. The green tea memory foam is used to make pillows, cushions and mattresses. Green tea foam in the top layer of a mattress acts as an antiodorant such that less of the chemical smell of the memory foam is perceived by the user. In addition, the bacteria and mold that would otherwise develop in the moist warmer sleeping environment on memory foam are killed by the green tea additive to the foam. Measurable antimicrobial and antiodorant qualities in the green tea foam are achievable by adding green tea powder constituting less than 2% of the weight of the resulting green tea foam.

    Abstract: A combined cushion and protective covering for a patient support having a patient-supporting surface comprises a central section having length and width dimensions corresponding substantially to corresponding dimensions of the support surface. 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.

  • Patent number: 7155765
    Abstract: A cushion having an elastic core and a pillow top layer or portion. The elastic core can have one or more layers of foam to provide varying degrees of cushioning and support. The pillow top layer is positioned adjacent to the elastic core and includes a plurality of strips. Any number of strips can form the pillow top layer. The strips can all have the same density or the density can vary among the strips to provide comfort zones. The pillow top layer can be connected to the elastic core in a variety of ways, such as through the use of a common cover or separate covers joined together.

  • Patent number: 7065816
    Abstract: A mattress (10) comprises a support base (12) defining an interface surface (14) at the top thereof and a softer compressible layer (22) overlying the interface surface. The thickness of the support base varies along a longitudinal direction such that the interface surface (14) defines a concave laterally extending channel between first and second support surfaces (16,20) for the upper and lower halves of a user's body respectively, and the compressible layer (22) substantially follows the profile of the interface surface (14). The mattress (10) is particularly useful for a pregnant woman who can comfortably lie on her back, side or front.

  • Patent number: 7059001
    Abstract: A mattress comprises a sealed outer casing within which is mounted a resilient support formed by a composite foam core. At least an upper portion of the resilient support is formed by a visco-elastic foam. A vent is provided in a side wall of the casing and is covered by a filter which prevents ingress of bacteria into the cover. A flap is mounted on the cover and in use extends down over the vent to prevent the filter being damaged by fluids.

  • Patent number: 7000277
    Abstract: A spring mattress that uses a multiplicity of elastic springs, spatially distributed according to a predetermined pattern, with highly variable configurations, obtained by shaping through cutting and pouring operations on a starting slab of foam material of a proper thickness. The resulting configuration that is adopted determines incoming portions in the spring elements that affect one or more of its sides, with variable magnitudes and depths, and outcropping portions from one or more of its sides, with a thickness and projection range that are also variable. The springs that make up the mattress are integrated on their lower end to the remaining continuous laminar portion of the original slab, and in a second alternate version, can be joined on their other end to a continuous laminar slab to which they are bonded by means of adhesion or similar operation.

  • Patent number: 6988287
    Abstract: A topper for selectively changing the firmness of a bed includes first and second sheets of foam which are bonded together at a flexible interface. The firmness of the first and second sheets differ, so that by putting one sheet face up on the bed one level of firmness is achieved, and by reversing the topper and putting the other sheet face up another level of firmness is achieved.
