Memory Foam

Memory foam products have become extremely popular and diverse since its introduction into commercial markets in the 1980s after initially being NASA tempur foam.

Technically known as polyurethane, it was adapted for greater viscosity (fluid thickness) and density through the addition of chemicals. It is sometimes referred to as visco-elastic polyurethane foam. The foam molds in response to body heat and to the shape of a body pressing against it and returns to its original shape after the pressure is removed.

Memory foam was developed in 1966 for NASA to improve the safety of aircraft seating. The heat-sensitive foam was initially called "temper foam" by one of its developers, Charles Yost. Yost went on to commercialise the foam with NASA and it was used in medical beds and sports helmets. NASA released it to the public in the early 1980s and used by the mattress and cushion company, Tempur World.

Subsequently, the material was used in medical settings as it helped to relieve bed pressure for bony bed-ridden patients. Over the years, the price has come down and NASA memory foam was used for many common household purposes such as mattresses, pillows and mattress toppers. It continues to be used for medical products such as wheelchair seats, hospital pillows and padding.

Mattresses

Visco-elastic mattresses are usually denser than other foam mattresses making them heavier and more supportive. The firmness of the foam determines how comfortable it will be. Some new foams emit an unpleasant odor but this should decrease with airing and a little time.
