Memory foam

Memory foam consists mainly of polyurethane with additional chemicals that increase its viscosity and density. It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam (LRPu). The foam bubbles or 'cells' are open, effectively creating a matrix through which air can move. Higher-density memory foam softens in…
