Sleeper Sofa/Pull Out Couch

That’s what I’d do. Saw one youstube recently with pivoting bookcases that was well done.

 

My favorite feature of our guest room.
Ive eyeballed this for my camper.

Since the space will be used as a lounge with a TV, and the room is tiny, I'm looking for a sofa bed.

 

I have limited space also.
I bought a used queen size sleeper sofa.
Replaced the shitty mattress with https://smile.amazon.com/gp/product/B00FZUX9OE/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 but they are out of stock.

I also bought https://smile.amazon.com/gp/product/B01N4N3QJ1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I sleep on the mattress replacement alone after I had surgery and it was pretty comfortable.
