Kim Kardashian and Kanye West have spent thousands of pounds on a ''magnetic bed''.

The 'Keeping Up With The Kardashians' star and the 'Only One' hitmaker have reportedly shelled out a hefty sum for the futuristic contraption, which holds a king-size bed five foot off the ground.

A source told the Daily Star newspaper: ''She and Kanye are absolute perfectionists who want the very best and won't settle for anything less.

''They are especially proud of the floating bed, although Kim does admit in a future episode that she only likes to hover a couple of feet up. She's worried she will forget they are up in the air and tumble out.''

In a future episode of the E! reality show, the couple - who have two-year-old daughter North together - will show off their £12.9 million mansion.

Their Hidden Hills home comes complete with a basketball court with its own changing rooms, costing £400,000 and a home cinema with enough space for 40 guests.

The stunning mansion also features a £40,000 antique copper bath tub, which is placed in their en-suite bathroom.
