How does memory foam work?

A memory foam pillow.

Viscoelastic foam is basically an insulating material that responds to changes in temperature. As the foam comes in contact with something that is warmer, the foam realigns itself to provide a cushion, softening where the body heats up the foam. When used on a mattress, it conforms to the contours of the human body, providing excellent support at pressure points along the spine, legs and elsewhere. This makes it possible to avoid some of the strains on the body’s skeletal and muscular systems that occur during sleep on any other type of surface. When a person changes position, the foam automatically realigns to maintain the cushioning effect.

Using memory foam can help an individual achieve deep REM sleep.

With the pressure evenly distributed throughout the body, there is less chance of waking up to find a more comfortable position. The end result is that it is possible to achieve deep REM sleep, which is the most restorative form of sleep. People with chronic back problems often find using a memory foam mattress to be particularly helpful in relieving pain.

Memory foam beds are ideal for people with sleep disorders.

While there are several excellent mattresses on the market today that are made from this material, the most effective models can be expensive. One way to find out if one of these might be a good solution to sleep problems is to invest in a memory foam pillow set. If the user finds that the pillows seem to be helping them to have a more restful sleep, purchasing a mattress made of this material would be the next logical step.

The development of memory foam came about because of the space program in the United States. The idea was to find ways to mitigate the negative effects of periods of acceleration and deceleration for astronauts who were in flight. Unfortunately, the foam that was ultimately created could not be used for this purpose, as it emits traces of gas that would accumulate in the ship’s closed atmosphere. The result of all this research was an ideal product for use in other ways.
