Memory foam is polyurethane product with additional chemicals added that increase its viscosity and density. It is sometimes referred to as “viscoelastic” polyurethane foam, or low-resilience polyurethane foam (see LRPu). Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes.
Our open-cell foams react to heat and weight, creating a whole new range of product possibilities. The density and thicknesses of memory foam can be manipulated to create unique solutions that fit your custom needs–literally!
Memory foam was developed in 1966 to improve the safety of aircraft cushions under a contract by NASA’s Ames Research Center. The temperature-sensitive memory foam was initially referred to as “slow spring back foam.” Memory foam is created by feeding gas into a polymer matrix. The foam has an open-cell solid structure that matches pressure against it, yet slowly springs back to its original shape, hence the name “memory foam.”
