ABSTRACT OF THE DISCLOSURE An upper mattress for reclining or seating furniture comprises a foam substance member preferably divided horizontally into two symmetrical halves. A plurality of cavities extend through the middle of the member or between the halves transversely to the longitudinal axis of the mattress. Each cavity is defined by a wall having a step forming a horizontal support shoulder ex- tending parallel to the longitudinal axis of the cavity. The shoulder is arranged between the apex of the cavity and the median plane so that the resilient reaction force of the mattress increases continuously with increasing loading and then, when the support shoulder is deflected so as to come into contact with an opposite part of the cavity wall, assumes a progressively increasing value.
