We have really been enjoying our RV overall but the bed in the rear corned can be a real torture chamber. The inboard mattress is solid 6 " foam and is fine but the outboard mattress has an inner frame to stiffen it over the outside storage locker. If an adult lies on the bed they (I) can feel the cross members through what I can assume is a 4 inch matress. It is possible to get comfortable if you lie on your back and slide down where your backside is between the cross members . However if you try to lay on your side the brace feels like it is going to cut you in two.. I was the shilverous one and slept on the outboard mattress on our trup to Branson to spare Jann the pain.
Early on, after spending one night on the bed I decided I needed to do something to mitigate the effect of the inner frame on the comfort or lack there of.
I got an idea that I got from the bunk boards we slept on as a kid, but when I unzipped the mattress cover I found that the frame was completely enclosed in the foam mattress. I tabled my idea and tried pads but nothing seemed to blunt the hard feel of the protruding cross bars.
I decided yesterday that sealed foam or not I was going to try my solution. I took a sharp pocket knife and I cut the mattress open along the seam ( holding my breath in fear that I would make a mess I could not correct.).
I was pleased to see that the frame was made of tubular aluminum but was astounded that the webbing was nothing more than plastic package binding strips, and some were not very tight. Regardless having cross members that are straight is a bad idea. All

As I was trying to say the cross members should be contoured so that the suspension straps can take the load without the mattress riding on the hard metal. If you look closely you can see that one of the straps is actually snapped.
I loaded the new OS 5 on my I pad and phone and now thay are slow and un responsive. Screwing up my posts.

I purchased a skeet of 1/4" luan plywood (actually about 3/16" or less) and cut a panel 20x74" and rounded the edges. I sanded the edges so that it would slide in without hanging up in the foam.
I slipped it in between the frame and mattress and glued the edge of the mattress using spray adhesive.
After gluing it up it was hard to see the seam where I had opened it up.
I put it back in the RV and took it for a test run with a mid afternoon nap. Though the mattress is only 4 inches thick on that side as opposed to 6" on the other it seemed to be pretty comfortable.

Not much fun traveling if your starved for sleep. Hope your idea works out for you. 3M 77 is good stuff. I've never run across anything that does the job better.
