Keystone Foam provides a variety of upholstery foam options designed for comfort, shape retention, and support in furniture. Polyurethane (PU) foam is popular for its flexibility, density range, and cost-effectiveness. Visco foam enhances comfort with its contouring abilities. These foams are flame-retardant, durable, and maintain support under frequent use while being soft enough for overall comfort. We also offer non-woven options, such as fiber, quilting rolls, and insulator pads.
