I need to try something different for the cabover bunk in my camper. The 4" foam mattress (54x80 inches) is killing my wife's back, even with a 1.5 inch memory foam topper. The camper is 20 years old, and the mattress is original. I am trying a full sized memory foam mattress, but it's 8 inches thick, and, of course too short, but it cuts badly into the space above the bed, and just barely allows the top to fold down.

I'm thinking about a 4 or 5 inch memory foam mattress 'topper' to replace the mattress, and maintain some space above the bed. Does anyone have experience with this? If I'm going to try a 'topper' as a mattress, how dense of memory foam should I use?
