Built to last: Heavyduty polyester fabric with a waterproof finish resists water, sunlight and stains to extend cushion life and maintain appearance. For longevity, store indoors during heavy rain or when not in use. Comfortable, overstuffed filling: Plush cotton interior provides generous support for seating while maintaining shape and resisting fading — designed for frequent outdoor use. Exact fit: Bench cushion measures 51.2' L x 19.7' W x 4' H, sized to fit most standard benches and seated areas. Secure, nonslip design: Two sets of antiskid straps keep the cushion firmly attached to the bench so it stays in place during use. Versatile compatibility: Works as a replacement or upgrade for a wide range of furniture — courtyard benches, patio furniture, wicker loveseats and settees, window seats, and porch swings. Practical use scenarios: Front porch bench: Add weatherresistant comfort for morning coffee or evening relaxation. Patio loveseat or wicker settee: worn cushions to refresh outdoor seating for guests. Window seat or porch swing: Create a soft, supportive surface for reading or lounging while keeping the look neat and secure. What you get: a durable, weatherresistant bench cushion (51.2' x 19.7' x 4') with overstuffed cotton fill and two antiskid straps — comfort and stability for indoor or outdoor seating.
