FAIRFIELD Project Foam is a multi-purpose polyurethane foam intended for household padding, protective layers, and light upholstery-style projects. This pack includes two 15 x 17 x 1 in (38.1 x 43.2 x 2.5 cm) sheets that can be trimmed for chair pads, craft cushioning, or protective storage inserts. Cut with a sharp blade for cleaner edges and keep the foam away from open flame or high heat, as with standard upholstery foams.
