Most likely you have the 'Steel flex' furniture. You can go on their website look at the products and color samples. Most likely you will receive help from the manufacturer. I was looking on a web site two days ago, just guessing here, RVTRUCKSAND FURNITURE. Just google RV furniture it will pop up. They make the couch for your dimensions at a fair price!
