Movement is becoming an important feature in interior design. A few weeks ago, Trendspotter wrote about the Hoverit air chair, which used magnets to give the user a feeling of floating. Now German designer Manuel Kloker harnesses one of the earth's natural energies in his Private Cloud bed, which provides its occupants with the ultimate rocktosleep.

The concept of the Private Cloud involves an ovalshaped, woodenframed bed that can roll around when pressure is placed on one or other of its ends. It looks like a giant rocking chair or, to be more exact, like a rocking bed.
