Invite your patio guests to relax and stay a while with this hinged indoor/outdoor Sunbrella lounge seat cushion. This polyester-filled cushion features a Sunbrella 100% acrylic cover that's resistant to weather and mildew, so you can feel comfortable leaving it outside. We love how its nautical navy-and-white striped pattern trimmed with red piping adds loads of coastal appeal to your deck or porch. To add this USA-made cushion to your lounge chair, simply secure it with the attached ties. Plus, the cover is removable (just unzip it), so it's easy to spot clean.
