reminds me of my old roommate in college, we had to fit 5 guys in a two bedroom apartment. He found/stole/bought (not sure which) some old scaffolding. He painted it and then got some 2x6's and made two queen sized bunk bed frames. So we had two decent sized beds in each room. Then, the last guy was on the couch (he was only there for the summer then back to the dorm).
