ABSTRACT OF THE DISCLOSURE An individually reversible thermal cushion includes at least one resilient layers, an insulating layer adjacent to the resilient layer or between resilient layers. The insulating layer has a reflective surface. A PVC top sheet and bottom sheet contain the resilient layer and the insulating layer. The resilient layer is made from polyurethane foam having a density of at least 1.8 lbs/cubic foot, and has a convoluted surface on at least one side, on which the domes have a diameter of approximately 2.5 inches at their base. The resilient layer may also be urethane foam, and/or polyester fiber stitched together in an appropriate quilted pattern. The reflective surface is aluminum vacuum deposited on one side of a polyethylene film laminated to a polyethylene film laminated to a polyurethane foam. The PVC top and bottom sheets may be vacuum formed to the contours of the resilient layer. - 21 -
