Abstract
A cushioncomprising a molded foam basewith an array of individual suspension elementsat the ischial area of the cushion. In one aspect the array of suspension elements is in a recessin the top of the base and in another aspect the array of suspension elements is in an inner cavitydefined by the base. The suspension elements are arranged in a pattern wherein the longitudinal axis of each suspension element in the array is positioned at a right angle or parallel to the longitudinal axes of the adjacent suspension elements. Each suspension element has a displaceable load-bearing surface, a first end wall, a second end wall, and an optional bottom wall, with load-bearing surface and recited walls defining an inner chamber. The material thickness of the load-bearing surface generally is greater than the material thickness of the end walls whereby the end walls deflect outwardly toward the load-bearing surfaces of adjacent support elements under load. The load-bearing surface can have a substantially arch-shaped, elliptical or rectangular cross-section.
