Charles Furniture's Tennis Ball Seat

Not all concepts stay in the design fairs - the Tennis Ball Seat (aka the Ballboy Stool) from Charles Furniture has actually made it into production.

Your eyes don't deceive you - this is a stainless steel frame and legs with 117 tennis balls to support your behind. And by all accounts, it;s incredibly comfortable.

The Tennis Ball Seat is being released in limited runs of 10, each one signed and numbered. How much? That isn't clear - although I would suspect you need to check your bank balance before dropping the company a line.
