The cushion (1) for body parts with a tendency to wear comprises a fluid-filled closed casing (4) of thin, flexible, stretchable material, e.g. rubber latex and inside the casing a sponge-type, porous, fluid-sucking material (8) which is compressible. When loaded by means of a body part, the inner material is deformable as the cushion conforms to the shape of the actual body part. |
