Discount Memory Foam Mattress Pad Memory foam, 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 his or her body, providing the perfect amount of support over an extended period — and particularly during periods of increased G-forces, such as lift-off and re-entry. The temperature-smart Sensus memory foam adjusts to your shape and your movement for all night comfort. The Origin of Discount Memory Foam Mattress Pad Sets Sensus memory foam was such a great success that hospitals began ordering memory foam mattresses for bedridden patients and burn victims. It didn't take long for someone to realize how attractive these Sensus memory foam mattresses would be to home users. A Swedish bedding company quickly turned concept into reality by marketing the first generation of memory foam mattresses to general consumers: Swedish memory foam, by Tempur-Pedic ®. That was a good mattress. A little too firm, in my opinion, but still a quality item. And it carries a price tag to match. Also from Mattress Pads Mattress Sets Pillows
