Ok have a Salem 272 rl, the couch cushion after less than one season had the foam start too roll around metal frame. That resulted in fan Eric covering being buckeled. Unhappy about that and after looking at my options I noticed the cover had a zipper. So icould not resist. Removed section at hinge, removed cover, and found foam was glued together and glue failed. A little spray glue 1/2 worth of work and we are good as new. Hopefully better.
Just wanted to pass along in case anyone has same issue.
