In 1950, Bertoia received an exciting invitation from Hans and Florence Knoll to work as a designer for their famous firm. Bertoia and his family relocated to Pennsylvania. By 1952, Bertoia had designed the famous "Diamond" seating collection, which included a lounge chair, stool, side chair, and a small chair for children. Constructed of industrial metal wire, the chair is remarkably strong despite its delicate appearance. Prized equally as a work of sculpture, it is still in production today and remains an icon of 20th century design.

Until his death in 1978, Bertoia was mainly active as a sculptor. Many of his sculptures are designed to move in the wind, some even to create sounds. He completed over 50 public sculptures in his lifetime, most notably for the chapel at the Massachusetts Institute of Technology and Dulles International Airport in Washington, DC. He was awarded the 1955 Fine Arts Medal, the 1956 AIA Craftsmanship Award, the 1968 Critic's Award, and the 1973 AIA Gold Medal.
