Designed by Dutchman Janjaap Ruijssenaars, it's got enough magnets to keep 900 kilograms (1,984 pounds) floating in the air. To make sure that the bed doesn't float away should it become windy (or "interesting," wink wink), it's tethered to the walls by four cables.

Technically, the magnetic floating bed is for sale, but at a price of 1.2 million euros ($1.53 million), you're not likely to find it in your local mattress store. – Nicholas Deleon
