ABSTRACT:
A vacuum or heat formed cushion having upstanding cells of thin (15-40 mil) wall thickness and having rectangular body sections with upwardly inclined (10.degree.-40.degree.) triangular top panels. The cushions can be attached together to form a mattress or used individually as a wheelchair or other chair or back cushion. The cells of the cushion can all be interconnected or the cushion can be divided in two or more independently inflated compartments. A special wheelchair cushion has cells of different shapes, sizes and heights to promote positioning of a user on a wheelchair. The cushion has openings through the base to allow it to be placed on a manifold so that body fluids can drain away from the patient and conditioned air can be supplied to the patient. The manifold has a top surface on which the cushion rests, side walls engaging the support surface to define an open area beneath the cushion, and a series of open segments in the top of the manifold aligned with the openings through the cushion base to allow air to be passed to and withdrawn from the area of the patient and to allow patient body fluids to drain into the manifold. The top surfaces of the cells are textured to prevent sealing off the pores of the user's skin.
