ABSTRACT:
A method of forming a spring cushion construction comprising a foamed pad having a generally flat inner surface with a depending peripheral edge, the flat inner surface including a dense outer crust. A spring assembly is disposed so that the terminal face portions thereof contact the outer crust and with the depending edge of the pad confiningly receiving the spring assembly to prevent lateral displacement therebetween. The pad is formed by a method which includes foaming a foamable material in an open top mold while leveling the upper surface of the foamable material in a manner which does not interfere with the formation of a dense outer crust thereon. The depending foam edge may then be formed by adding additional foamable material along the periphery of the pad, or by suitably attaching a preformed foam strip therealong.
