We actually solved the bad mattress problem buy purchasing a queen memory foam mattress like you would use at home. We used an electric knife to cut the mattress to size without cutting through the last 2" of foam or the top mattress cover. Electric knife worked amazingly well and was easy to use. It now folds where it needs to and sleeps just as well as new. We did cover the exposed foam with fabric and because the original cover had a zipper (unexpected) we stitched around the cut zipper edges and used a little glue to keep the zipper from splitting. It has worked perfectly. Maybe this solution will help someone else.
