BACKGROUND
Memory foam mattresses were first introduced in the early 1990′s under the brand name Tempur-Pedic. NASA scientists invented the original concept of visco elastic foam, as a cushioning material to absorb the affects of G forces during take off, though they believed the concept would be best utilized in consumer applications. Memory foam is a unique material in that it contours to the shape of the sleeper, and distributes the applied weight evenly over its surface to eliminate pressure points caused by heavier areas like hips and shoulders.
