I'm an NYC apartment dweller, and my guests sleep in the living room. I need a new couch that is either a convertible or a daybed. The big, hulking, pull-out couch won't do, as it takes up all the room, and it's unwieldy--I have to move too much furniture to open it.

Does anyone have a suggestion for manufacturers or stores or websites that make stylish and functional daybeds or convertible couches?
