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).
