Abstract: Hospital mattresses are generally made of foam plastic having predominantly open cell cores and are in the form of a parallel-epipedic block which is provided with a protective layer consisting of a plastic film which is easy to clean so that injurious substances and bacteria can be removed. Such mattresses have the drawback, however, that when used they produce sounds which are disturbing. These sounds are eliminated in accordance with the present invention by arranging a layer of fabric between the outer surface of the foam plastic block and the protective layer.

Abstract: A mattress or pillow for hospital use generally consisting of a core of parallel-epipedic shape formed of elastic plastic having open cells, a layer of elastic plastic having open cells secured by heat-lamination to said core but having a shorter solidification time than the core. Said construction then being entirely covered by a protective film formed of a plastic which is heat-laminated to the layer of elastic plastic and which is easy to clean and disinfect.

Abstract: Hospital mattresses are generally made of foam plastic having predominantly open cell cores and are in the form of a parallel-epipedic block (1) which is provided with a protective layer (12 and 13) consisting of a plastic film which is easy to clean so that injurious substances and bacteria can be removed. Such mattresses have the drawback, however, that when used they produce sounds which are disturbing. These sounds are eliminated in accordance with the present invention by arranging a layer of fabric (9 and 10) between the outer surface of the foam plastic block (1) and the protective layer (12 and 13).
