Are the sofa beds good quality? Can one sleep comfortably?

Sofa bed is very firm but not uncomfortable. Won’t feel any metal in your back. I was complaining then I woke up 7 hours later. Lol

I'm considering a listing with 2 kings/ 2 sofa beds. Is the second sofa bed typically located in the second bedroom? I would assume one sofa bed is located in the living area.

Thanks!

is sofa bed a queen size or full size? D.P mentioned earlier that it is firm but not bad. Anyone has picture of the sofa bed after it pulls out? Just wonder if it is ok for an adult to sleep and not hurt his/her back; if it is firm and thin, we might have to consider 3 BR instead :( (cost more). Thanks.
