Abstract (en)

1. A seat and/or back cushion (11, 12) of a first foamed plastics material, made of an open-pore polyurethane foam with a particular indentation hardness and density, in which is foamed at least one foamed plastics body (131-137) at right angles to the seat direction to form a foamed plastics reinforcement, which provides the cushion with greater indentation hardness than that of the first foamed plastics material, the foamed plastics bodies (131-137) themselves forming the reinforcements, characterized in that the foamed plastics bodies (131-137) consist of a second foamed plastics material, namely closed-pore polyurethane foam or open-pore melamine foam or the like, whose density is lower and whose indentation hardness higher than those of the first foamed plastics material.
