Memory foam beds have become popular because they are comfortable. Visco-elastic foam, an invention of the NASA, is a "memory foam" that provides support to the entire body by reliving pressure on joints, including the back. Those with chronic back pain or joint pain find relief sleeping on a memory foam bed mattress.
As with any bed, try it out before you buy. Climb on and lie on your back. Mattress selection is always a very personal thing and a memory foam mattresses is no different. So be sure you satisfy yourself that the mattress you are trying will give you pressure relief and adequate support. Only buy what you feel will give you a good nights sleep.
NASA's memory foam was invented in order to reduce the stress of G-Force on astronauts during space travel. During re-entry, it is memory foam that relieves pressure on astronaut's joints as they descend back to Earth.
Memory foam actually molds itself perfectly to the contour of the body thus relieving any pressure points. It gives the mild sensation as if you were sleeping on air. On a queen- or king- sized bed two sleeping partners will be much less aware of the movements of the other during the night. This is a good feature if someone tends to toss and turn a lot. Your partner will not be disturbed by the movement.
Memory foam beds are truly a space-age product.
