Abstract
A body support mattress of compressible foam has a body supporting surface sliced to define an array of contiguous polygonal blocks each having a load bearing surface. The blocks are interconnected by foam links integral with the pad, and the foam links are individually rupturable under load to adapt to the support requirements of particular users and relieve shear stress on a body resting on the mattress.
