[[File:MemoryFoam-fast.jpg|thumb|Memory foam]]'''Memory foam''' consists mainly of [[polyurethane]] with additional chemicals that increase its [[viscosity]] and [[density]]. It is often referred to as "[[viscoelasticity|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 reaction to body heat, allowing it to mold to a warm body in a few minutes. Newer foams may recover their original shape more quickly.<ref>Nelles, Barbara.
