Bed couch with draws, shared room, space saver. this could go in bedroom area. like the shelves idea, too. can add a light wooden dining table and a few comfy folding chairs to make cool dining area in bedrm space, if bed moves to living room area.
kids bed with lots of storage. I kind of like this type of bunk bed where underneath is the whole dresser. Then having two in the room for my boys versus a regular bunk bed.
