Memory Foam Beds : Why You Should Sleep On a Memory Foam Bed

By: Ray Lam. A good night's sleep is important if you want to look energetic the next morning. People have always been trying new technologies for better sleeping and they would like to pay up to thousands for improved beds and mattresses. The visco elastic foam is a revolutionary sleeping technology that would relieve pressure points.

Memory foam was discovered by NASA back in the 1970s, but was not durable enough to hold up for more than about a year or two. This did not make for a very marketable mattress, but that all changed in the 1990s. A Sweedish company discovered a way to put memory foam into a bed and make it work for a longer amount of time.

Foam density is widely regarded by foam manufacturers as the main factor determining the durability of a high density foam mattress. Durability is the ability of foam to retain its original comfort and support characteristics. In general, higher density beds are more durable. They are also more expensive to produce due to greater material content.

But do not get scared away. Generally speaking, if you suffer back or neck pains, then memory foam mattress could be the solution. The memory foam mattress is soft and it forms to your body night after night. and your spine will be in the right alignment.

Foam is made up of thousands of tiny cells. The cells are formed by a polyurethane wall and filled with space (air). Higher density foams have thicker cell walls and less space inside. Lower density foam has thinner walls, greater space. If foam were made too dense, its cell walls would be too thick / stiff. It would be hard to the touch and would not conform to the body properly. It costs more to make dense foam, and at some point it can be made too dense. So there is a balance that needs to be struck between performance, cost, and durability. The marketplace today has gathered around a 5 lb memory foam mattress as the optimal choice for bedding. While more expensive than lower density foams, it provides better, long term contouring support.
