I finally broke down and bought a bed today. It's supposed to be delivered on wednesday sometime. I am SO glad I won't have to decide between sleeping in the living room and dragging my futon mattress into the bedroom anymore.
Plus, adding another large piece of furniture brings me a /little/ bit closer to actually filling this apartment to the point where it looks like someone lives here, which is nice. All I've got to do after this is find something to put on the walls, since they look a bit empty now.
