"This 3-piece set of seat and back all-in-one cushions completes your modern patio sofa for ultimate relaxation on the porch or in the yard. Each 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 sofa when selecting a size (based on availability).
