Suggestions for reinforcing sofa of a sofa bed

We purchased a new fifth wheel last year. The love seat/ bed sinks when you sit in it due to the gap between the cushions and bed underneath. I have tried packing sleeping bags on top of the folded bed and under the sofa cushions, but then it's lumpy. Does anyone have any suggestions.

The sofa bed in my fifth wheel was horrible and I tried everything.

When traveling back from an assignment, I went under a low bridge and totaled the trailer. Now I have a new trailer with a great sofa bed.:S

I had the SAME thing happen to mine. It's not just the need to reinforcing it it is the whole darn workmanship of the whole frame from the manufacturing.

Called a Mobile RV repair guy. Said he sees this happen all the time.

His Fix?

Well he took the whole couch out and showed me all the cheap thin particle board that holds these couches up and attached to the wall. Most was split and just shredded. Screwed with screws way too short etc etc.

He ripped it all out and He built me a frame with 2x4's and screwed it back together with screws the correct length.

Couch was like brand new and even sat up higher and opened an closed better than when I bought it.

Whole thing took about an hour or so and the repair bill was so cheap I gave the guy a bonus!

My advice is Call Mobile RV repair they see this cheap workmanship the manufactures use over and over again and know how to fix it. :C

We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us.

On my list to do. I have heard that is the way to go many times. I plan to replace the foam in the seats with some QUALITY foam.

we used blankets folded up evenly inside the folds of the mattress. Worked very well
