I saw this on a friends Facebook page and thought it quite intriguing. It's a room in a box.

Yes, a whole room in a tiny box measuring just 31x47 inches. Included in the box is your living room, bedroom and office.

It takes only about 10 minutes to set up and you don't need any tools in order to do it.  I can see these being used in college dorms, big city's and shelters. Pretty clever idea but that bed looks really, really uncomfortable and I would so need a bigger closet!
