Couch in 3875

We have recently purchased a 2016 Bighorn 3875 w bath and a half. One concern we have so far is the couch in living area. We often have our son and family with us for a night or two. We were very disappointed in how the couch folds out to make into a bed. It is uncomfortable and very difficult to put sheets on it. Has anyone changed out the couch to a hide a bed couch? Is it hard to remove?
Thanks doe any ideas on this issue.
