Crest FeltCrest compressed polyurethane foam is a unique, environmentally friendly, flexible foam material that has been permanently compressed to a predetermined thickness. It is made from a wide selection of uncompressed foams manufactured by Crest. For each application, a foam is selected which exhibits the desired properties, then sliced to the proper precompressed thickness. The sliced foam sheet is then permanently compressed through a precisely controlled thermal setting process to form FeltCrest.
