Memory foam mattresses are made from revolutionary new visco-elastic foam, designed originally for the N.A.S.A program and then commercially manufactured by the Swedish Company Tempur.
This new technological mattress relieves pressure points because it is able to mould to the exact shape of your body. Conforming and contouring to provide optimum posture. It is also asthma and allergy friendly.
The memory foam mattress is a sandwich construction, made up of cheaper base support foam (which may be contoured) to which the more expensive upper memory foam layer is bonded. This foam sandwich is covered by material which should be a knitted soft stretch fabric to allow the cover to move easily with the memory foam.
The quality of the mattress and the cost are dependent on the thickness of the sandwich and the quality and construction of the foam and the fabric of the cover.
