Thin-layered alternating material body support and method of manufacturing same

Abstract

A body support assembly comprising a first layer comprising a visco-elastic foam (e.g., a non-reticulated foam), a second layer supporting the first layer and comprising a non-visco-elastic foam (e.g., a latex foam), and a third layer supporting the second layer and comprising a visco-elastic foam (e.g., a non-reticulated foam). In one embodiment, a thickness of the first layer is less than 20% (preferably less than 10%) of a total thickness of the body support assembly, and a combined thickness of all visco-elastic layers is less than 50% of the total thickness. Preferably, the thickness of the first layer is less than 3 centimeters. The body support assembly includes a first layer comprising non-reticulated, visco-elastic foam, a second layer comprising a material different than non-reticulated, visco-elastic foam, a third layer comprising visco-elastic foam, a fourth layer comprising a material different than non-reticulated, visco-elastic foam, and a fifth layer comprising visco-elastic foam.
