How Do Memory And Air Mattresses Work?
Viscoelastic foam is made of open cells, billions of balloons with holes in them. When you sit on it, air moves from one cell to another and the mattress contours your body in a unique fashion, relieving pressure points and supporting your weight. With regular foam mattresses, which are made of closed cells, the air in the compressed cells pushes back against you causing pressure points which constricts circulation at the area of contact. The result is discomfort and even pain over time. When you lie on a visco foam mattress there is no air left in the cells to push back and cause discomfort. The air is spread to adjoining cells and the foam simply ‘melts’ under you to provide long-term, balanced support and comfort.
