The Cloud Levitating Sofa may be coolest furniture ever designed by the engineers. David Koo and Zheng Yawei are the two Hong Kong designers came up with the idea of a floating sofa which appears like a cloud. In the Cloud sofa, the soft floating upper part is supported by the magnetic force generated by the bottom base. You can work and sit with comfort or simply nap to release the stress, you can always enjoy your time to relax on the floating cloud. Unfortunately, the engineers have to work on this concept, as the natural magnets are not strong enough to support a person and to hold him steady in the air and the electromagnets are too expensive. Whatever it is, the Cloud sofa worth a wait. However, this design honored as it is mentioned in Yanko Design’s RELAX 2009 competition.
