Abstract: A mattress consists of two outer layers of cotton material (3), under which there is provided two layers of plastic foam material (1), in that these four layers are sewn together with stitching (4) in such a manner that there are formed compartments or channels which can be filled with particles of synthetic material (2). Such a mattress is capable at one and the same time of dissipating moisture while keeping the body warm by insulation, while simultaneously influencing the body with an advantageous massaging effect which, among other things, prevents bedsores and the like.
