Polyurethane is a polymer created during a chemical reaction between polyol and diisocyanate (two chemicals created from organic compounds). The ratio of polyol to diisocyanate is 2:1 to form polyurethane, though there may be other compounds that are added to create just the right amount of density and elasticity for each piece of foam. The foam is synthesized, poured into molds, and cooled before cutting into mattress layers.
Polyurethane foam can be used in every layer of the mattress. Popular memory foam mattresses are almost all blends of polyurethane foams.
