This ARDEN outdoor seat cushion brings a comfy and boho feel to your favorite patio chair. Its cover is crafted from a polyester blend that's resistant to fading/UV rays and water for holding up to everyday use on your deck or urban balcony. The design features blue and white stripes of various sizes for a more eclectic look, finished off with piped edges. We love that this cushion comes filled with foam for padding and support. Our favorite? It comes with two ties on the back to keep it securely in place on your chair. It measures 21'' wide by 21'' deep.
