Thomas Heatherwick’s Extrusions work represents the world’s first single component of metal furniture, extruded by machine.

Each seat – mirror polished aluminium made without fixtures or fittings – has been produced by the world’s largest extrusion machine.

Heatherwick Studio commissioned a specially designed die through which aluminium was ‘squeezed’ into a chair profile, complete with legs, seat and back. The die shape is laser-cut in to the front cover of the book accompanying the project.

Also included is an essay on the production process behind the work and a review of selected projects by Heatherwick studio.

Published to accompany the exhibition Thomas Heatherwick: Extrusions at Haunch of Venison, London (September – November 2009).
