Are there materials that can substitute for flexible polyurethane foam?
A. In furniture and bedding applications, short staple polyester fiber is often used instead of FPF, as is cotton, but both alternative materials have poor height recovery characteristics after compression. Steel springs also recover well but must be insulated from the user with some type of cushioning material. Comparing FPF to alternative materials in the areas of economics, comfort potential, ease of use, and durability, there is not an acceptable substitute for FPF.
