Problems solved by technology

Although the number and types of body supports constructed with one or more visco-elastic materials continue to increase, the capabilities of such materials are often underutilized.
In many cases, this underutilization is due to poor body support design and / or the choice of material(s) used in the body support.

Embodiment Construction

[0029] A body support 102 according to an embodiment of the present invention is illustrated in FIGS. 1, 1A, and 1B, and comprises two layers of material: a top layer 110 comprising open-celled non-reticulated visco-elastic foam (sometimes referred to as “memory foam” or “low resilience foam”) and a bottom layer 112 comprising reticulated non-visco-elastic foam. In some embodiments, the top layer 110 can rest upon the bottom layer 112 without being secured thereto. However, in other embodiments, the top and bottom layers 110, 112 are secured to one another by adhesive or cohesive bonding material, by being bonded together during formation of the top and bottom layers 110, 112, by tape, hook and loop fastener material, conventional fasteners, stitches extending at least partially through the top and bottom layers 110, 112, or in any other suitable manner.

[0030] Each of the top and bottom layers 110, 112 can be substantially flat bodies having substantially planar top and bottom surf...

Abstract

A body support comprising a top layer of flexible visco-elastic material having an exposed convoluted top surface is disclosed. The flexible visco-elastic material can have a reticulated or non-reticulated cellular structure. In some embodiments, one or more other layers of the body support comprises reticulated visco-elastic foam, and can have at least one material property responsive to temperatures in the range of a user's body heat. In these and other embodiments, one or more of the other layers of flexible material comprises non-visco-elastic foam, and can be combined in a body support with one or more layers of visco-elastic foam. The body support can include one or more layers of other material types, including one or more layers of high-resilience polyurethane foam.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Priority is hereby claimed to U.S. patent application Ser. No. 11 / 166,594 filed on Jun. 24, 2005, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION [0002] Conventional body supports can be found in a wide variety of shapes and sizes, and are often adapted for supporting one or more body parts of a user. As used herein, the term “body support” includes without limitation any deformable element adapted to support one or more parts or all of a human or animal in any position. Examples of body supports include mattresses, pillows, and cushions of any type, including those for use in beds, seats, and in other applications. [0003] Many body supports are constructed entirely or partially out of foam material. For example, polyurethane foam is commonly used in many mattresses, pillows, and cushions, and can be used alone or in combination with other types of cushion materials. In many body supports, visco-...
