Comfort Gel Cushion

Sandwiched by high-density foam, the inner layer of gel relieves pressure and evenly distributes weight  up to 225 lbs. Removable waterproof cushion is protected on one side by bright blue heavy-duty nylon; the other side is backed by soft, durable vinyl. The cloth-like nylon holds in warmth while the vinyl provides cooling relief. Refrigerate cushion for extended cooling. Two hook-and-loop straps attach to back of chair or wheelchair to hold cushion in place. Dimensions:  16" x 18" x 2".
