Definition of Slow Recovery Foam

Meaning of the Term as it Pertains to Mattresses

What is Slow-Recovery Foam?

Slow-recovery foam is a general term applied to common memory foam. Also called visco-elastic foam or low-resilience polyurethane foam, slow-recovery foam gradually compresses when force is applied to the surface. When force is removed, the foam takes a few moments to regain its original shape. For example, if you press down with your hand and quickly pull it away, a distinct hand impression lasts for a moment and then slowly fades away.

Because of its slow-reacting nature, slow-recovery foam absorbs and dampens energy exceptionally well and conforms to the shape of the load applied to it. These traits make it an ideal material for use in mattresses. The foam cuts down vibrations when an individual moves and holds the body in place when the body lies still.

Slow-recovery foam is produced in the same manner as conventional polyurethane foam but uses additional chemicals and adapted processing techniques to give it visco-elastic qualities. As a result, slow-recovery foams tend to be more expensive than typical polyurethane foam.
