Memory Foam is heat sensitive Memory Foam is heat sensitive, visco-elastic foam. With in minutes at room temperature, memory foam will mold itself to the shape of the body. The foam holds this shape temporarily - a hand pressed into memory foam will leave a clear impression when removed. The Swedish company, Tempur-Pedic, developed memory foam for NASA for use in the space program. NASA adopted memory foam because of its ability to distribute pressure across the entire surface, easing the pressure of extreme G forces. The health professionals realized memory foam applications. It is now widely used in hospitals, nursing homes and hospices, to ease the pain and suffering of patients confined for long periods to bed. Initially, memory foam was too expensive for general use. In recent years, visco-elastic memory foam has become cheaper to produce, making it available for the home bedroom. The most common domestic applications of memory foam are in mattresses, pillows, and mattress toppers, or mattress pads. The denser memory foam mattress is more supportive but also heavier than an ordinary foam mattress. Because of its density, memory foam is often a good compromise between the comfort of a soft mattress and the supportiveness of a firm one. New, memory foam often gives off a distinct unpleasant chemical odor. This odor does fade with airing however some people remain sensitive to it.. All about memory foam:
