Abstract A cushion or mattress is provided which is formed of a plastic foam structure having top and bottom walls containing a plurality of coil springs extending between the top and bottom walls, each of the coil springs being completely enclosed in a synthetic fabric casing, and the springs and casings completely filling the interior of the foam structure in a side-by-side relationship. The top and bottom of the casings are adhesively bonded to the inner surface of the top and bottom walls, and no clips or ties of an kind are required in the construction of the product. The foam structure is composed of latex or urethane foam, and the casings are formed of a fabric material composed of olefin, nylon and polyester. The adhesive has a strong affinity for the foam and for the synthetic fabric so that a thin layer of the adhesive provides an instantaneous firm bond between the foam and the synthetic fabric.
