Your Adirondack chairs will be even more comfortable when you add this set of 2 padded high back cushions. These comfy 2 inch thick foam filled polyester cushions are covered with a water-resistant olefin finish for indoor\/outdoor use. An elastic back strap securely fastens these cushions to your patio chairs to ensure they stay in place when you stand or sit. Use a damp cloth to wipe clean or remove the zippered covers to hand wash and air dry for a deeper clean to ensure your cushions look great all season long.
