ABSTRACT:
A sponge cushion material is suitable for use as a carpet underlay. The sponge cushion has a cellular layer bonded to two nonwoven textile layers which can delaminate. The carpet is adhesively bonded to the cellular layer and one of the textile layers is adhesively bonded to a floor. The carpet can be easily removed by pulling it away from the floor so that the two textile layers delaminate and one of the textile layers remains bonded to the floor.
