I moderated a panel talk with Nicola Stäubli (along with two other young Swiss who won 2011's Swiss Design Prize) and learned a lot about his "Reversible" chair prototype. It's made of metal tubing that can be re-assembled into two leg configurations, shown here in its lounge arrangement at left and its dining chair form at right. The fabric cover is removable, and as a product, it's simple and ingenious.
