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). Featuring a delicate filigreed appearance that’s supremely strong, these airy seats are sculpted out of steel rods. In his art, Bertoia experimented with open forms and metal work, and these 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 the authentic Bertoia Diamond Lounge Chair produced by Knoll. The Knoll logo is stamped into its base. Chair made in Italy; seat pad made in U.S.A.

  • In honor of Bertoia’s 100th birthday, Knoll has introduced a version of this classic finished in 18-karat plated gold.
  • Black and White frames can be used outdoors with limited exposure to the elements. Chrome and Gold frames are not for outdoor use.
  • Vinyl seat pad can be used outdoors and is secured to chair with metal snaps. Bouclé full cover is not for outdoor use.
