This 1-piece outdoor seat cushion instantly softens your patio dining chair. It's filled with foam for extra padding and support, and it's wrapped in a Sunbrella® cover that zips easily around the removable inset. The cover is made from water- and weather-resistant acrylic, and it comes in a range of colors and patterns to suit your outdoor design scheme. Plus, it ties easily to your patio chair so it doesn't fall out of place. To care for this outdoor seat cushion, we recommend dry cleaning it as needed.
