Particularly advantageous is the creation of upholstery, which is particularly suitable for vehicle seats and a shaped Pad made of elastomeric urethane foam has a Multiple integral layers with different degrees of resistance for compressive loads with a transition zone between adjacent layers, which have an intercellular connection with one another and the resistance against the compression of the layers from an outer layer to the inner layer increases in such a way that the compressibility of the padding decreases from one outer to the other outer layer

According to the invention, it is expedient to create a cushion for a vehicle seat with a shaped cushion of an elastomeric urethane foam with a plurality of one-piece layers with different degrees of resistance to compression with a transition zone between the layers _s where a membrane-free intercellular connection is provided between adjacent layers _s and. with an integral, impenetrable, & still * ^ 3 _Ststo; ff _e having urethane skin, which is formed on at least a part of the outer surface of the padding in such a way that the outer skin partially penetrates through the adjacent foam cells and is united with them.

Furthermore, according to the invention, it is advantageous to have a vehicle timing structure to create, which has an elastomeric foam padding as the padding material, the padding quickly and. can be easily installed on and removed from a support frame «
