Memory foam is also known as memory foam, memory foam and viscoelastic foam. Memory foam reacts to body heat and can therefore adapt perfectly to the contours of your body, so you do not feel any pressure points in memory foam. Especially for bedridden people, memory foam is therefore very pleasant.
How fast or slow memory foam 'springs back' depends on the thickness of the wall of the air chambers in the foam. The thicker the wall, the longer it takes until the air is drawn back into the air chamber, and the slower the foam reacts.
