# what sort of set up would i need to create an electro magnetic chair with no legs

I am a furniture design student therefore please keep it simple. a system strong enough to hold the avergae male of say 90 kg is this possible even....

This is still a challenging problem today, because something would be needed to keep the seat of the chair from drifting laterally. A fixture could be used to hold it in, but any such fixture would be more expensive/impractical than simply having legs on the chair. –  Ataraxia May 21 '13 at 6:52

Some has done this with a bed http://www.dvice.com/archives/2012/05/maglev-bed-lets.php. With the use of the naturally strong rare earth magnets (neodymium magnets). For a chair it would be hard to levitate the chair any reasonable distance, as you would need a decently powerful magnet.
