Uncomfortable Sofa

I'd look at a furniture store. Take your measurements along, and pick out what you like

Hard to find a comfortable one.
Watch the weight.

This, 100% this.

We had to replace a set of recliners and we just shopped at normal furniture stores for replacements.

Get a comfortable replacement couch that will fit the designated space. Maybe even get a love-seat style that reclines. Forget about finding one that folds out to a bed. NONE are comfortable. And I've slept on dozens and dozens of hide-a-bed's in homes and RV's. None!

Instead, just get an inflatable air mattress that has it's own built in air pump and put it on the floor when you need extra sleeping space. We used an inflatable mattress on the floor in our previous camper because the fold out bed was so horribly uncomfortable.

Our current 5er has 2 opposing slides in the front living room with hide-a-bed, tri-fold outs that almost touch each other in the middle. They are horribly uncomfortable to sleep on. Problem solved.... we got 2 matching air mattresses and put them on top of each fold out bed. With just a push of a button they inflate and deflate. They worked great, but they work even better on the floor, and take up the same space.

I wouldn't worry about the sleeper feature, I do some of my best sleeping in a recliner.

A comfortable sofa bed is an oxymoron sort of like an honest politician or an honest used car salesman!

Interestingly, my 2004 Itasca's jack-knife sofa is surprisingly comfortable, both for sitting AND sleeping. And that has been verified by several different people who have slept on it.

I put a few strips of wood in the bottom of my rv sofa. I also used upgraded foam from an auto upholstery shop and what a difference.

All for just a few dollars....

Twice that steelhunter said. Plywood might help - gives the seat backs some slope/comfort.
As for sleeping, when we had a similar problem, I took a 2" foam pad and cut it to fit the top square of the bed. Meaning everything but the couch cushions. We then put a fitted sheet over it to hold the pad in place, and that made our sofa a better place to sleep, comfortable at least.

We always thought that the purpose of a Sleeper Couch is to ensure that your company doesn’t stay very long!
