The comforting finishing touch for the Adirondack Chair, the Adirondack Seat Cushion from Loll Designs offers ultimate relaxation and versatile style. Made of Sunbrella fabric, this seat cushion is naturally fade-resistant and water-resistant to ensure lasting use. The cushion is held in place via two velcro straps that tie around the back of the chair, securing the square-shaped piece to the seat of a chair without interfering with its clean and simple design.
