We had your problem, a futon was the solution, it wasn't real comfy but it was better than the couch it came with. The problem with a replacement is getting the old couch out the narrow door, we actually had to saw it in pieces. We had to put the futon frame together once we got it inside and we folded the mattress in half and tied it together and were able to get it through the door. We had that for about a year and decided to get rid of it because it wasn't that comfy. We got two recliners, most recliners have backs that come off so they come in two pieces. Easy peasy getting them in the door. We are very happy with the recliners. If one of the grandkids goes with us they sleep on an air mattress in a sleeping bag. We live in Calif. and are able to camp year round, we are lucky to be able to do that.
