Early production Diamond chair in white and black painted metal with rust-orange velvet pad.

The Bertoia Diamond Armchair, originally designed in 1952 is one of the most iconic designs by Harry Bertoia, who was not only a furniture designer but also a sculptor.

Harry Bertoia (1915–1978) was an Italian-born American sculptor and designer, celebrated for his innovative wire furniture and monumental public sculptures. After studying art and metalwork in Detroit and at Cranbrook Academy of Art, Bertoia contributed to the development of the Eames plywood chairs before joining Knoll Associates, where he created his most famous work: the Diamond Chair. This sculptural seat, formed from a welded wire lattice, became a mid-century modern icon. Bertoia’s later years were dedicated to sound sculptures, known as Sonambient, which combined visual and auditory art. His legacy endures through the continued production of his furniture and his influence on contemporary design.
