"This seat cushion brings comfort and a clean look to your outdoor seating area. It features a D-shaped silhouette specifically designed to fit a variety of benches. Its cover is made from Sunbrella fabric® for a soft-toned fabric feel that stands up to the elements while resisting fading. The fiber-wrapped foam fill provides a supportive seat for relaxing on the patio or deck. We love that the reversible design and zipper closure make it easy to maintain a fresh look throughout the seasons.
