Known for his open metal sculpture of the late 1940s and ’50s, Bertoia studied at the Cranbrook Academy of Art and began his career teaching in the metal shop there in 1938. He began working for Knoll in 1946 and set up his own studio near the manufacturer’s Pennsylvania factory. He saw chairs as functional sculpture.

The Diamond chair is in the shape of a diamond in its overall structure and is made of a diamond patterned heavy wire mesh. Padding provided comfort but disrupted the transparency of the openwork design. Several variations on this chair were designed, including a child’s version, and this version continues in production today.
