What Is Memory Foam?

Tuesday, May 6th, 2008

Little bits of heaven, thats what.

But seriously, exactly what is memory foam?

Memory foam is made from polyurethane with additional chemicals that add to its viscosity level, thereby increasing its density. It is often referred to as visco-elastic polyurethane foam. Depending on the chemicals used and its overall density, it is firmer in cool temperatures and softer when warm. Higher density memory foam reacts to body heat which allows it to mould itself to the shape of a warm body within a few minutes.

What makes it so much better than a normal mattress?

Memory Foam Mattresses provide much more natural support for your body as you sleep. They last longer than normal mattresses. They allow you to rest comfortably and wake up without any aches or pains.

Who invented memory foam?

Memory foam was originally developed by NASA to decrease the very high pressure caused by the extreme g-force occurring during the take-off of the space shuttle. It was never used in the space program but was subsequently used medically, for example by patients who used to lie in bed on hard or very firm mattresses for long periods of time without regularly moving such as being bed-bound after a paralyzing stroke. The pressure over some of their bony regions decreased or stopped the blood flow to the region causing horrific pressure sores and/or gangrene. Memory foam mattresses helped hugely to decrease such events.

Why is a Memory Foam Mattress so much heavier than a normal one?

A memory foam mattress is usually denser than an ordinary foam mattress. This makes it more supportive but also heavier. It is often seen as a good compromise between the comfort of a soft mattress and the supportiveness of a firm one.
