The ARDEN Oceantex Dining Chair Cushion Set is a top-of-the-line environmentally friendly outdoor cushion featuring premium recycled fabric. This olefin fabric is made from 50% recycled ocean bound fishing nets. The pillow back measures 23 in W x 17 in L x 5 in T and the seat bottom measures 21 in W x 21 in L x 4 in T. It provides extended UV protection so your cushion can last longer and limit your environmental impact through fewer repurchases. One recovered commercial ocean bound fishing net can be transformed into over 100 cushions and pillows. Inside this dining chair cushion is partially recycled polyester fiber fill to help it retain shape and provide long-lasting comfort during outdoor use. Although this dining chair cushion is both water and UV-resistant, we recommend bringing it indoors when it rains or when not in use to preserve its lifespan and keep it looking beautiful. This season enjoy your outdoor space knowing that you have made an environmentally conscious and family-friendly decision you can feel good about.
