ABSTRACT:
A method of making a mattress comprising a framework of metal springs sandwiched between first and second sheets of foam, comprises applying a strip of foamable resin mixture around the periphery of the upper surface the first sheet of foam being disposed horizontally, and then laying the framework on the upper surface. The strip is allowed to foam to engulf at least a portion of the lower part of the framework which is thus adhered to the first sheet. The framework is then similarly adhered to the second sheet.
