Spun Outdoor Chair by for .

The Spun chair began as an exploration into whether the process of metal spinning could be used to create something to sit on. As the finished object would be a completely symmetrical rotational form it would have to be able to work as a chair whichever way round it was rotated.

Full-size models were experimented with and gradually tweaked and refined until the optimum shape was discovered.

Heatherwick initially produced a limited series of metal chairs and then went on to collaborate with the Italian furniture manufacturer, Magis, to develop a version using rotation moulded polypropylene.

The plastic chair is covered with a detail of fine ridges, like the grooves on an old vinyl record, which add comfort and reinforce the rotational shape of the form.
