It is 21" square and really comfy. The only thing that is not "recycled" or "saved from the trash" is the berry colored piping. I got it at a closing out sale, so it comes close. The pieces of material were not wide enough to not have seams on the face of the cushion, so I put piping in those seams. I think the valance/window topper I started out with may have been made from previously used material too as it was made up of several smaller strips sewn together. I undid all the seams to get back to scratch. The piping is the same on both sides and around the entire outside seam.
