"This seat and back cushion all-in-one complete your modern lounge chair for ultimate relaxation on the porch or in the yard. It has an interior insert made from a foam blend for just the right amount of support. The design features an acrylic Sunbrella fabric cover with piped edges, available in a variety of hues, that's removable with a quick zip for easy cleaning. We love that this upholstery is specially created to be resistant to weather, UV/fading, and stains for holding up to everyday use. Make sure to measure your chair when selecting a size (based on availability).
