A foam core cushion mattress assembly provides semi-independent foam pillars on the upper surface of the mattress. The mattress may be unitary, or comprise multiple cushioning components, possibly base, body support and foot cushions. The body support cushion is constructed from a flat, rectangular solid, foam element whose upper surface is cut into an array of rectangular solid pillars, preferably by a hot wire cutting method. The array of rectangular solid pillars is grouped into a central array comprising pillars with generally square top surfaces and edge rows of rectangular solid pillars having rectangular top surfaces. The depth of the hot wire cuts into the surface of the body support cushion is preferably approximately one-half the overall thickness of the body support cushion or approximately three fourths of the length of the shortest face of the pillar. A zippered fabric cover removeably envelops the assembled cushioning components. The resultant structure defines a plurality of semi-independently compressible pillars that support a reclining, or supine patient. The pillars may also be cut into the top and bottom surfaces of the cushion for enhanced pressure relieving effects. Methods of manufacture, and treatment and alleviation of decubitus ulcer formation are also presented.
