Our ARDEN earthFIBER Deep Seat Set is made with long-lasting foam fill and outdoor earthFIBER fabric. earthFIBER fabric is made from our new ultra-soft plant-based fabric! The most eco-friendly cushion fabric on the market made of a blend of bamboo viscose and polyester and PFAS-free C0 treatment. The pillow back measures 23 in W x 19 in L x 5.5 in T and the bottom cushion measures 22 in W x 24 in L x 4 in T. Our plant-based outdoor fabric resists fading, so your patio cushion set looks vibrant for longer. Skin-safe C0 water protection helps your cushion set withstand continued outdoor use, while cleaning easily with just soap and water for low-maintenance upkeep. Although this deep seat cushion set 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.
