With his iconic seating collection, Harry Bertoia transformed industrial wire rods into a new furniture form. The events that made this work possible began a decade earlier at Cranbrook Academy of Art, when Bertoia met Florence Knoll (then Florence Schust). Years later, the Italian-born designer was invited to work for Florence and her husband, Hans Knoll. Bertoia was given the freedom to work on whatever suited him, without being held to a strict design agenda, and the result of this arrangement was the Bertoia Seating Collection (1952). These extremely strong yet airy chairs are sculpted out of steel rods with a delicate filigreed appearance. In his art, Bertoia experimented with open forms and metal work, and his chairs were an extension of that work. “If you look at the chairs, they are mainly made of air, like sculpture,” said Bertoia. “Space passes through them.” After designing his seating collection, Bertoia returned to focusing mostly on sculpture. This is an authentic Bertoia Diamond Lounge Chair produced by Knoll, with the Knoll logo stamped into its base. Seat pad is secured with metal snaps. Chair made in Italy; seat pad made in U.S.A.
