Curatorial Remarks: First manufactured by Knoll in 1952, the welded-steel-rod Diamond armchair by Harry Bertoia added dynamism to modern seating. Its open frame, supporting a grid of smaller diamond shapes, glorified the use of a new industrial material. Bertoia wrote about the graceful design: “My feeling was that it had to come almost from an inward direction. . . . I began to rely once more on my own body. . . . The chairs are studies in space, form, and metal, too.” The continued success of the Diamond armchair is attributable to its seamless melding of aesthetics and practicality, seen in the best mid-century American design.
