This Greendale Home Fashions Outdoor Seat/Back Combination Chair Cushion is the perfect complement 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 durable polyester fabric holds up to the outdoor elements so your cushions stay looking great. 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. Please measure your cushions before purchase to ensure a proper fit. Please Note: Cushion dimensions can be +/- 2 inches. Product will arrive in a slightly compressed state; please allow a few days for product to expand to final size listed in description. In an effort to reduce waste, your cushions will arrive in a recyclable box with no additional plastic waste. For best results, and to extend the life of your cushions we recommend storing them covered when not in use.
