Design Harry Bertoia, 1952. Welded steel rods, upholstery. Made in USA by Knoll. Harry Bertoia's 1950 experiment with bending metal rods into practical art produced a revered collection of seating, including the exquisite Diamond chair. Innovative, comfortable and strikingly handsome, the chair's delicate appearance belies its strength and durability. In Bertoia's own words, "If you look at these chairs, they are mainly made of air, like sculpture. Space passes right through them." A classic, modern design that enhances any environment, Bertoia's Diamond chair remains a fascinating study in bent metal and a fixture of mid-century design. Knoll is the only authorized and licensed manufacturer of the Bertoia Collection which has been in continuous production since 1952. The Bertoia Diamond chair with full cover is not suitable for outdoor environments. 33.5" w | 28.25" d | 30" h | seat: 16.5" h.
