Designed by Heatherwick Studio, Spun is an attempt to make a chair with perfect rotational symmetry – it’s circular and balanced on a single point, like a spinning top. Sit in it and tilt to one side, and it begins to roll until you feel like you’re about to topple over backwards.

 

Instead, you come full circle, rising back up to where you started. Made from moulded polyethylene, for manufacturer Magis.
