Jo-Ann Fabric and Craft Stores sell several types and brands of foam, such as Air-Lite extra high-density polyurethane, Airtex heavy duty, Pellon outdoor and Fairfield cushion. Foams are available in rolls, slabs and cushions.
As of 2015, Jo-Ann operates over 800 stores in 49 states as well as its online store, JoAnn.com. A larger selection of foams is available online than in stores.
Use the 4-inch thick, Air-Lite extra high-density foam rolls as toppers for mattresses. The largest size available online fits a standard queen-sized mattress, 60 inches by 82 inches. The Pellon outdoor foam, designed for outdoor cushions and pads, is mildew resistant and does not break down from outdoor exposure.
