Full-Size daybeds?

Does anyone know of a daybed/combined couch and bed (not a pull-out) solution that would fit a full size mattress? A twin seems a bit too narrow for me, but the only option I've seen for daybeds is twin sized. My place is too small to fit a bed and couch alongside my other stuff, and I'd rather not sleep on a pull-out every night.

I know about the Hemnes daybed, but I've seen conflicting reviews. What do y'all think?
