The Knoxville, Tenn.-based Polyurethane Foam Association is developing a certification program called CertiPUR-US for polyurethane foam. The voluntary program, which is based on a similar European program, will include recommended guidelines for flexible polyurethane-foam products in the areas of environmental, health and safety performance based on analysis of foam components and emission characteristics. Physical performance standards will help quantify durability, consistency and comfort. For more information, visit
