You can credit a Dutchman by the name of Janjaap Ruijssenaars for making one of the coolest pieces of furniture I’ve ever seen. He’s apparently dedicated the last six years of his life to the project, which is wholly understandable – I can’t think of anything more worthwhile.
There’s no anti-gravity gubbins involved; it merely uses magnets to stay off the ground, can carry a weight of 900kg and is held in place by some virtually invisible tethers. This presumably wouldn’t stop your 'best mate' snipping the guides with some scissors and pushing you in a blissful slumber away from the magnets holding you up!
Only the wealthiest of heads will be able to rest on its pillows anyway – a full-sized model is expected to cost €1.2 million (£832,000). It would keep me up all night worrying about how much it cost!
