Sofa or Bunk Bed?

Made by Resource Furniture, this clever living room rig looks like an ordinary sofa at first glance. But when you lift up the parts, you end up with an impressive double-decker, complete with separate mattresses, safety rails and a built-in ladder.  How cool?

It's cool because it saves a lot of space and according to the product page, the sofa opens up into the two-level beds with a single lifting motion, so you even save your own energy! When you want a bed in two seconds, this does the job.
