"Diamond" Chair by Harry Bertoia for Knoll


'Diamond' chair designed by Harry Bertoia for Knoll, in white enameled stainless steel on a welded black steel base. Please note: Pickup for this chair is in Denver, CO. The diamond chair is, according to Knoll, an astounding study in space, form and function by one of the master sculptors of the last century. In Bertoia's own words: 'If you look at these chairs, there are mainly made of air, like sculpture. Space passes right through them.' But although these chairs are like a sculpture, Bertoia first though of comfort and went through the procedure of positioning, considering the possibility of shapes, then relating what the wire could be, what shape it could take. Dick Schultz, who worked with Bertoia on the development of the collection, says of the first chair he saw in prototype form: 'It was remarkable. I was asthonised by the order of it - like something that grew out of nature. The Harry Bertoia’s wire chairs are among the most recognized achievements of Mid-Century Modern design and a proud part of the Knoll heritage.

About Knoll (Manufacturer)

As a company that produced many of the most famous and iconic furniture designs of the 20th century, Knoll was a chief influence in the rise of modern design in the United States. Led by Florence Knoll, the firm would draw stellar talents such as Ludwig Mies van der Rohe and Eero Saarinen into its compass. Their work would help change the face of the American home and office.

     The company was formed in 1938 by the German immigrant Hans Knoll. He first worked with his fellow ex-pat, the Danish designer Jens Risom, who created furniture with flowing lines made of wood. While Risom served in World War II, in 1943 Knoll met his future wife, Florence Schust. She had studied and worked with eminent emigré leaders of the Bauhaus, including Mies, Walter Gropius and Marcel Breuer. She won Knoll over with Bauhaus notions of industrial arts, and an aesthetic that featured flat and tubular metal frames and angular forms. When Hans died in a car crash in 1955, Florence Knoll was appointed head of the company. It was as much through her holistic approach to design—a core division of the firm was dedicated to planning office systems—as Knoll furnishings themselves that she brought about the sleek and efficient transformation of the American workplace.

     Today, classic Knoll furnishings remain staples of modern design collections and decors. A history of modern design is written in pieces such as Mies’ elegant Barcelona Chair, Saarinen’s pedestal Tulip chair, Breuer’s tubular steel Wassily chair and the grid-patterned Diamond chair by Harry Bertoia. As you can see from the items on the following pages, these designs and others have become timeless emblems of the progressive spirit and sleek sophistication of the best of Modernism.
