When you can draw the design of an object with one single line, and do that even after you only saw it briefly more than a week ago, then you know you've encountered something special.

Lounge chair Onda by Spanish designer Diego Granese consists of a single piece of stainless steel, covered with leather. It saw the light in 2003 and is produced by the Spanish furniture manufacturer Frajumar.

I haven't been able to try it for myself, but it looks like quite the balancing act. Either way, a great conversation piece.
