Abstract:
1. A bedding comprising a single composite foam, the composite foam comprising: a top layer of latex foam and a second layer of an open-celled foam selected from polyolefin, polyurethane, polystyrene or polyester or visco-elastic latex or mixtures thereof, wherein the top layer and the second layer are coextensive to each other and wherein in use, the composite foam is oriented such that the top layer is directed towards the top surface of the bedding and wherein composite foam layer is obtained by spreading and vulcanizing a liquid latex foam layer on the second layer, thereby causing the liquid latex to enter into the open-cells on the surface of the foam of the second layer and vulcanize in said cells, and thus connecting both layers to obtain a single composite foam without applying glue or any other mechanical connection means, and wherein the vulcanized liquid latex layer has a thickness of 0.5 cm to 6 cm on top of the second layer, and wherein the second layer has a lower indentation load deflection value than the top layer.
