Memory foam was first developed in 1966 by NASA to improve the safety of aircraft cushions. Subsequently it was used in medical settings. It was commonly used in cases where patient was required to lie immobile in their bed on a firm mattress for an unhealthy period of time. The pressure on some of their body regions impaired the blood flow to the region, causing pressure sores or gangrene. Memory foam mattresses significantly decreased such events.
It was previously expensive limiting its use. But it became cheaper gradually and now is used commonly in mattresses, pillows, shoes and blankets. It is also referred to as viscoelastic polyurethane foam or low resilience polyurethane foam.
Memory foam molds to the body in response to heat and pressure, evenly distributing body weight. It returns to original pressure once pressure is removed.
