I have a fairly long and narrow space that I'd like to use as a living room by day and a bedroom by night - so naturally I'm looking for a sofa bed. I really like the kind where the mattress stores completely inside the sofa, because I can keep the bed made and I won't have to sleep on couch cushions. However, because the room is only about 90" wide, most of those fold-out sofa beds would go right to the wall if they fit at all.

I have plenty of width to work with, so does anyone know of any good "horizontal" fold-out sofa beds, where something like a full-size mattress pops out but you sleep with your head at one end of the couch and your feet at the other?

I haven't been able to find one yet after visiting a few stores. Thanks for any help.
