Nasa foam Memory mattresses, technically visco elastic foam, was originally developed by NASA for use by astronauts. The idea was to create a foam that would sense the body temperature and weight of the astronaut and then gently conform to the shape of the body, providing the perfect amount of support over an extended period of time and particularly during periods of increased G-forces, such as lift off and re-entry. It didn't take long for someone to realize how attractive these memory foam mattresses would be to home users. A Swedish bedding company quickly turned concept into reality by marketing the first generation of nasa memory foam mattresses to general consumers.

Nasa foam memory mattresses, is a foam that responds to the body's temperature and then perfectly conforms to the body's shape. As the memory foam gently conforms to the body it redistributes the body's weight. More of the body is in contact with the sleep surface: The more square inches of contact, the less overall pressure per square inch. This conformability of the memory foam allows every square inch of the body to be supported and thereby significantly reduces skin pressure by as much as 50%. This improves the circulation, reduces pressure points as well as spinal pressure.
