Combined cushion and protective cover and methods of forming

A combined cushion and protective covering for a patient support having a patient-supporting surface comprises a central section having length and width dimensions corresponding substantially to corresponding dimensions of the support surface. Flaps which are unitary with the central section extend from the side edges of the central section a distance beyond the side edges of the support surface. The flaps are thinner than the central section so as to depend from the central section and lie alongside the patient-supporting surface. The central section and the flaps are formed simultaneously by compressing a block of cushioning material in such manner that the central section forms a pad or cushion unitarily joined at its opposite sides to the flaps. During the compression of the block to form the central pad and the flaps the external surfaces of the pad and flaps are heated to an extent sufficient to enable the surfaces of the pad and flaps to form a smooth, moisture proof skin.
