Memory foam is polyurethane with additional chemicals increasing its viscosity and density.

It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam (LRPu).

Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes.

Newer foams may recover more quickly to their original shape.
