The back to back seat's have bases that measure 24" wide by 38 3/4" long and the seats are 20 1/4" tall where they attach to the hull on the outersides of the seats. The engine cover is about 34" wide and 50" long. The picture of the bottom seat where the stitching has come apart is the worst one. The other 3 are ready to come apart but haven't yet. The close up pics show the worst of the seats.
