The invention relates to a leather layer system used as a coating for a foam material body. The invention further relates to a cushioning element and to a method for producing the cushioning element.The leather layer system is provided with a leather layer, a foam material layer and an adhesion layer. The adhesive layer is located between the leather layer and the foam material layer and is usedfor connecting the foam material layer with the leather layer in a planar mode. The foam material layer faces the inner side of the leather layer system, the leather layer faces the outer side of theleather layer system, and the foam material body is formed inside a chamber defined by the inner side of the leather layer system through an in-situ foaming process. According to the invention, the foam material layer is made of ethylene propylene diene monomer and has a semi-closed cell structure.
