furniture bertoia chair

Harry Bertoia designed five wire pieces that became known as the Bertoia Collection for Knoll. Among these was the famous diamond chair, a fluid, sculptural form made from a welded lattice work of steel. In Bertoia's own words, 'If you look at these chairs, they are mainly made of air, like sculpture. Space passes right…The chairs were produced with varying degrees of upholstery over their light grid-work, and they were handmade at first because a suitable mass production process could not be found. Unfortunately, the chair edge utilized two thin wires welded on either side of the mesh seat. This design had been granted a patent to the Eames for the wire chair produced by Herman Miller. Herman Miller eventually won and Bertoia & Knoll redesigned the seat edge, using a thicker, single wire, and grinding down the edge of the seat wires at a smooth angle - the same way the chairs are still produced.
