An efficient bed

While ordinary mattresses force the body to adapt to them, this mattress hugs the body by uniformly distributing loads.

The spine thus remains straight, thanks to its efficiency in "memorizing" the pressure applied by a body. 

Viscoelastic toam is already used in mattresses designed to prevent bed sores in hospitals.

According to sleep problem specialists, lying down on a bed with a memory foam mattress gives the impression

you are floating in space. Since we spend a third of our lifetime in bed, we might as well be comfortable.

On the other hand, this kind of comfort doesn't come cheaply since these mattresses are sold anywhere from $1,500

to more than $5,000. Mattress toppers start at $100.00.
