ABSTRACT:
A laminated support pad includes layers of material having different density in which voids are formed to extend through at least partial cross-sections of at least two adjacent layers to form regions of the pad having different support characteristics determined by the placement and extent of the voids in the laminated layers. Lamination of a layer of high density material on top of a layer of relatively low density material produces a relatively firm pad having varying degrees of firmness dependent upon the placement and extent of the voids. Conversely, lamination of layer of low density material on a top surface of a layer of relatively high density material produces a relatively soft pad also having varying degrees of firmness dependent upon the placement and extent of the voids. The pad can be cut to conform to conventional mattress sizes, and the regions formed in areas of the pad which correspond to the weight bearing requirements for optimum support of the human body in prone positions.
