Source Of Memory Foam

　　Memory foam, also known as viscoelastic foam, was originally a NASA innovation in 1966 as a material used in aircraft seats to reduce the force and pressure of g-forces during takeoff and landing . The discovery of its properties and benefits quickly permeated the medical field as it provided a comfortable and sensitive material for patients in intensive care units and wheelchairs. In the 1990s, the material was sold to a public company that went on to change the game in the mattress and sleep, divisions. However, it was very expensive to produce during its introductory phase. Thanks to its commercialization, new ways to make it cheaper have been implemented over the years.

　　Memory foam is a synthetic material called viscoelastic foam. It differs from other foams because it has greater resistance, making it an ideal material for mattresses.

　　It's soft and durable, with heat-wicking properties to support aching joints. This makes it popular with sleepers of all sizes and sleep styles. Memory foam also comes in different firmnesses, so you can find a mattress that suits your sleeping habits.

　　Memory foam is denser than various other types of foam, so memory foam mattresses may be heavier, but generally take up less space than traditional spring mattresses. Also, memory foam pillows are less likely to bunch up like feather pillows. Another advantage of memory foam over traditional bedding (spring mattresses, feather pillows, etc.) may be greater resistance to the growth of dust mites, a known allergen in sensitive individuals.
