The airy seats of the Bertoia Seating Collection (1952) have a delicate, filigreed construction and a relaxed sit. Sculpted out of supremely strong steel rods, the collection was an extension of Harry Bertoia's work in sculpture and remains one of the most iconic contributions to modern furniture design. This is the authentic Bertoia Diamond Lounge Chair produced by Knoll. A sign of authenticity, the Knoll logo is stamped into its base. Chair made in Italy; seat pad made in U.S.A.
