Memory Foam: Pressure
built 633 days ago
Memory foam was originally developed by NASA to ease the pressure of extreme G-force during space shuttle take off. It was never used in the space program, but was subsequently used in medical applications, for example with patients suffering from pressure sores or bed-bound for a long period.

The visco-elastic material from which memory foam is made was first developed by NASA in the 1970s. It is an Open Cell Space-Age foam that was developed to be used in space shuttles to reduce the effects of the gravitational forces that Astronauts would feel during take-off and return. Since then, memory foam was shown to be unique in the way it responded to temperature and ... in ability to spread pressure over a greater surface area (and thereby reduce pressure points significantly).

After memory foam was developed as part of a NASA project, some saw the promise of memory foam for use in the medical industry to relieve pressure sores. Over the years, memory foam was shown to be unique in the way it responded to temperature and ... in its ability to spread pressure over a greater surface area (and thereby reducing pressure points significantly). While the initial version of the foam developed for NASA (called T-Foam) did have a great deal of promise as a bed topper or wheel chair cushion material, it did have issues with wear over time. This first generation of material wasn't very durable, and would often compress or crack over time.
