ABSTRACT:
A low-profile multilayer cushion assembly which can be used to support the human body under various conditions. The cushion assembly generally includes a top layer of supportive material having a relatively high compression modulus, a middle layer of woven material, and a bottom layer. The bottom layer includes a matrix of supportive material having a relatively low compression modulus and an arrangement of inserts spread throughout the matrix having a relatively high compression modulus. In the preferred embodiment closed-cell polyurethane foam is used for the top layer and inserts, and open-cell polyurethane foam is used for the bottom layer matrix. The inserts are adhesively attached to the matrix to provide additional resistance to buckling. An optional protective cover encases the bottom layer, middle layer, and top layer.
