Rapidly expanding beyond the war uses it was initially designed for, polyurethane foam today is one of the more wildly used materials around. The diversity of uses is also impressive – polyurethane foam can be found in everything from medical research labs to the cushions in your couch or chair. Polyurethane foam is also finding a use in economy mattresses because of its long-lasting comfort and affordability, as well as a way to reduce the costs of memory foam or latex foam mattresses by being used as a base. Polyurethane cushion foam is known as Qualux Foam for premium uses and Resilitex Foam for more economy uses.

It is sensitive to the heat the human body emits and has the ability to automatically adjust to body weig
