Our ARDEN Deep Seat Set is made with long-lasting foam fill and performance olefin outdoor fabric. The pillow back measures 24" W x 21" L x 6.5" H and the bottom cushion measures 24" W x 24" L x 5.75" H. The 100% woven olefin outdoor fabric resists fading, so your patio cushion looks vibrant for longer. Durable olefin fabric helps your cushion set withstand continued outdoor use and two sets of ties on the seat bottom make sure your cushion stays firmly in place.
