ABSTRACT:
A cushion comprising an array of individual suspension elements arranged in a pattern wherein one embodiment 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 and may be constructed from different materials to make a composite suspension element. The bottom wall of the suspension element may have a small vent opening of a predetermined size to allow a controlled release of air from the inner chamber under load to enhance the viscous feel of the cushion. The cushion also includes a cover enclosing the array of suspension elements.
