The Seat Outdoor XPWS0149 Cushion from Polywood is a well-constructed piece that attaches with fabric ties and is built to hold its position during regular use across various outdoor settings. The performance fabric cover resists moisture, salt, sun, mold, and mildew, and the foam and blended polyester fiber fill provides consistent support over time. Quick-drying and easy to clean with soap and water, it is designed to perform reliably without requiring special care between seasons.
