These beds soften as they warm to body temperature. They're made of billions of microscopic open cells that spread your weight evenly across your body while you're sleeping.
Instead of pushing up against you like traditional inner spring mattresses, memory material softens and gives way under your body weight, adapting to your every contour. It eliminates pressure points that can disturb your sleep. These beds help to align the spine correctly and cushions your body so you wake up feeling refreshed.
For a mattress, this visco elastic material is layered over a firmer core to provide support. Memory foam is not only used in beds but also in pillows and mattress overlays.
The term visco is derived from the word viscosity which often pertains to a liquid which is thick and flows slowly, like honey. The inventor of NASA memory foam referred to his new material as "slow foam". It became known as visco elastic foam because it was slow to spring back to its original shape.
A memory foam mattress is a boon for people who have health and sleep problems that confine them to hospital beds. Since a visco elastic mattress offers gentle support to the body there is no hindrance to the circulation of blood at the pressure points which leads to bed sores in people who have to spend a long time in bed.
These beds help to relieve the aches and pains that you gain throughout the day. If you have annoying neck and back pains, a NASA bed will be particularly beneficial for you.
Headache sufferers find that memory beds may help to alleviate the pain. This is because they relieve the pressure on the back and the neck that you may experience sleeping on other types of beds. This not only reduces the intensity but also the frequency of headaches.
