The ARDEN Basics Outdoor Deep Seat Cushion Set is made with long-lasting outdoor polyester fabric. This outdoor deep seat set includes 1 pillow back and 1 seat bottom. The deep seat pillow cushion measures 24 in W x 21 in L x 6 in H and deep seat bottom measures 22 in W x 24 in L x 4.5 in H. The 100% printed polyester outdoor fabric resists fading, so your patio cushion looks vibrant for longer. Two sets of ties on the deep seat bottom make sure your outdoor deep seat set stays firmly in place. Inside this deep seat set is 100% recycled polyester blowfill in the pillow and partially recycled polyester fiber fill in the seat to help it retain its shape and provide long-lasting comfort during outdoor use. Although this cushion is water- and UV-resistant, we recommend bringing it indoors when it rains or is not in use to preserve its lifespan and keep it looking beautiful.
