This Greendale Home Fashions Outdoor Seat/Back Combination Chair Cushion is the perfect compliment to your outdoor furniture. It measures 42 x 21 x 5 inches, and comes with four string ties which allow for a secure attachment to outdoor chairs. Eight circle tacks give the cushion dimension and a full appearance, while preventing cushion fill from shifting and increasing durability. The cushion's 100% polyester, UV coated fabric is fade, stain and water resistant. The cushion's polyfiber fill is made from 100% recycled, post-consumer plastic bottles, and overstuffed for added comfort, strength and durability. A variety of colors and prints are available to enhance your outdoor decor.
