What people should realize is that tempurpedic mattresses are no different from memory foam beds. These are also beds whose technology was taken from NASA but it is just this kind of mattresses have a higher foam density than the ordinary foam beds.
Memory foam beds are medically tested to make sure that they live up to the purpose of their development, which is to protect the bones. Sleeping on beds that are either too soft or either too hard can cause bone deformities such as scoliosis. This is also the reason people suffer from a stiff neck after a long night of sleep.

Unfortunately, long hours of sleep does not really equate to quality sleep. The goal of tempurpedic mattresses is to make sure that the person sleeping reaches a state called Rapid Eye Movement or REM. this is the deepest state of sleep in which a person really allows the body to recuperate. The cells regenerate faster and in a more efficient manner if REM is achieved during sleep.
The history of tempurpedic mattress began as part of a revolutionary technology developed in NASA to counter the heavy pull of gravity the astronauts experience during lift-off.
Unfortunately, it wasn't successful and was never used in any space mission. However, the Swedish company Tempur saw the potential of its use in residential and medical industries and later developed the tempurpedic mattress, beds and other related bedding items.
Today, it is one of the most popular brands of memory foam mattresses and is used in many hospitals as well as homes because of its visco elastic properties.
