Medium density polyurethane foam

Medium density polyurethane foam is a medium quality foam that is best used in moderately priced furniture including sofas, chairs and certain types of outdoor furniture. It can also be used as the base in certain types of custom mattresses, or as a base to provide support for higher quality foams like memory foam and latex foam. Medium density foam tends to fall between the high 1.8 pound range to just under a 3lb range. It may be referred to as an H series foam with appropriate numbers denoting its firmness, such as H21 (soft), H30 (medium) and H45 (firm). If it encounters everyday use the lifespan for the foam is typically 4 to 6 years.
