Want to sleep on a floating bed? Created by Reddit poster 'mememetatata' the floating part of the bed is held up by a set of strong neodymium rare earth magnets in the base underneath.
The top section is tethered with a thick steel cable, and the bed is then free to float by itself. It's capable of lifting 250 pounds which is perfect even if you're a little on the large side. But don't expect to have this bed for two. Unless of course, the two of you are tiny.
