The Standard Outdoor Seat Cushion from Polywood features a simple, versatile design that attaches securely with fabric ties for a snug fit on most outdoor chairs. Hand-sewn outdoor performance fabric surrounds a foam and blended polyester fiber fill. The cushion resists moisture, salt, sun, mold, and mildew, and it dries quickly after exposure to rain. It cleans easily with soap and water, making routine maintenance simple.
