Your next piece of designer furniture could cost less than an Ikea chair—as long as you’re willing to make it yourself. Taking a cue from the Linux community and file-sharing services, Berlin-based design guru Ronen Kadushin has started a furniture free-for-all he calls Open Design. It allows crafty consumers to download the instructions, photos, and AutoCAD files needed to knock off his work.

Plank

Plank is a six-foot length of solid wood, which can be folded into a coffee table, side table or stool and folded out again to make a plank. It works because its four joints, engineered to high tolerances, cross the board at slight angles, causing it to spiral as it folds.   Designed by Thomas Heatherwick.

Concrete Chair

With  nod to Le Corbusier  (its a copy of a LC Club chair except the upholstery is concrete).  

Obviously not really made for a person to sit on, but as an interesting art object.
