Sofa?

we were in the same situation as you are. ours came with out a dinette booth, bed mattress and a jack knife sofa. The mattress we had made from a mattress shop which ended up way more reasonable than any place on line. The dinette booth I made and had cushions made and the sofa I originally order from amazon but latter found out the same shop the sold us the mattress was a distributor for that brand of jack knife sofa, so we bought it from him for a better price. If you can fit a quality sofa sleeper in there do it. Our jack knife sofa is not comfortable to sit for long let alone to sleep on, for our grand children its fine. Maybe the more expensive ones are better. All sofa sleepers are bolted together some place in there.
