The Combi-Air mattress is designed with a revolutionary 3D technique channelling air through the corrugation material design through to the memory foam layer reducing heat and also allowing air to flow more freely whilst retaining moisture that can evaporate the result is dryer sleep experience. With the patented layer of 3D high density foam on the surface of the mattress, another feature is the second layer made of laytech offering more spring than a standard memory mattress and thus giving more support whilst allowing movement, excellent performance and durability.
