Sharon; we have two different size front full width cushions. One is wider, (front to back) than the other. The upper bunk was missing in our Uhaul
so I'm not sure of what their original placement was, but we used the wide one as the bottom, and the narrow one as the back, for a front couch. Now we have a captains chair from a Casita
mounted in the corner inside the door, and one of the curved cushions that would have been in the rear, the one that's about 3 or 4 feet long, as the bottom, and a rectangular one that's about 2 feet long as the back to finish off the front as a couch. So you could use those cushions maybe as patterns?
