All memory foam mattresses are comprised of laminated sections of foam. Usually, there is the block of base polyurethane foam (non memory) and on top of this is glued a layer of viscoelastic foam (memory). Many manufacturers have now inserted a layer of convoluted high-density foam (air flow layer - non memory), between the base and top layers, to help dissolve body heat.

Before you buy a Tempurpedic mattress, you should compare it to another brand of memory foam mattress. Other brands can be just as plush and some can be a lot less expensive.
