System for manufacturing pressure or impact receiving bodies designed to achieve directable cushioning

A mattress comprising a directable cushioning system comprising two pressure or impact receiving bodies complementing each other (1 and 1′), each comprising a generally planar surface on one side and a series of protuberances (2 and 2′) on the side opposed, with the two bodies (1 and 1′) being of an elastic nature and of different densities, characterised by the less denser (1′) of the two bodies being shorter than the denser body (1) in the elongated direction of the planar surfaces and being supported on the top of the denser body with the two bodies (1 and 1′) being joined by means of their protuberances (2 and 2′), which are inclined with respect to their generally planar surfaces and each of the pressure receiving bodies comprising a first group of the protuberances inclined with respect to their generally planar surfaces in a first direction and a second group of the protuberances inclined with respect to their generally planar surfaces in a second direction opposite to the first direction;

• with the two bodies being assembled by means of their protuberances (2 and 2′) inserted between each other whereby, upon the provision of pressure or impact on the generally planar surface of one of the bodies, the resultant forces cause the tilted protuberances to bend and the shorter, less dense body (1′) to move in an elongated direction relative to the longer, denser lower body (1) due to the bending of the tilted protuberances under forces applied between the planar surfaces of the two bodies (1 and 1′).
