Good idea: couch/ guest bed

I love this idea on Apartment Therapy. Corner sofa by day, sleeping room for 2 by night. Probably wouldn't put it in my living room, but in a family room, guest room/office, or den of some sort would be a great space saving solution. Trista and I probably would have loved something like this when we were sharing a room. (Click on the photo to see more pics and read how it's done.)
