Diamond ChairBy Harry Bertoia

About the Design

To fully understand the design of Harry Bertoia’s (1915–78) 1952 Diamond chair — an austere and photogenic work of woven steel wire, the intricately sculptural wings of which create the illusion of sitting on air — it helps to go back to his college days: In 1937, the Italian-born artist and designer, who emigrated to Detroit at age 15, earned a scholarship to Cranbrook Academy of Art, the illustrious Michigan design school that attracted such luminaries as Florence Knoll, Eero Saarinen and Charles and Ray Eames. Bertoia was deeply influenced by the Eameses, especially by the sculptural quality that was so prominent in the furniture they made. In the 1940s, he left Cranbrook to work for the couple, developing the molded plywood furniture that would become a trademark of their designs.

Bertoia learned to weld while employed by the Eameses, but left their workshop in anger over the lack of credit he received for the important contributions he made there — a dispute that would come to play an important role in the Diamond chair’s development. He eventually took a job at an electronics lab, where he analyzed human mobility for the purpose of designing electronics with easy-to-reach knobs and consoles. 

When his former Cranbrook classmate Florence Knoll tapped Bertoia to make furniture for the Pennsylvania company she had recently founded with her husband, Hans, the designer was swayed with the promise of full credit for designs he produced. Armed with a newly minted background in ergonomics as well as the knowledge he gathered from experimentation with the Eameses, Bertoia capably applied what he’d learned over the years at Knoll, where he utilized thin wires of welded metal to produce pieces that appeared to be floating in the wind — yet remained surprisingly comfortable and supportive. The Diamond chair, a widely revered component of the innovative metal furniture line that Bertoia designed at the company, has been in continuous production at Knoll since 1952 and is available in four finishes today.

Mid-Century 'Diamond' Chair in Leather by Harry Bertoia for Knoll, USA, c. 1960s
By Harry Bertoia
Located in Deland, FL
Introducing a rare and limited "Diamond" chair designed by the influential Harry Bertoia for Knoll. First designed in 1952 for Knoll, the diamond chair was by far Bertoia's most famous and recognized design and formed part of his 5-piece wire-made body of work for Knoll called the "Bertoia Collection". The Diamond chair is characterized by a fluid, sculptural form made from a welded lattice work of steel. In Bertoia's own words, "If you look at these chairs, they are mainly made of air, like (a) sculpture. Space passes right through them." The chairs were produced with varying degrees of upholstery over their light grid-work, and they were handmade at first because a suitable mass production process could not be found and that's exactly how the upholstery was redone in our shop - by hand. Featuring new upholstery, cut from an authentic mustard-colored Italian leather hide, this iconic Diamond chair is ready for a literal lifetime more of use. Harry Bertoia was an Italian-born welder, sculpture and designer who after moving to the US in 1930, began studying design at Cranbrook Academy of Art where he met and befriended the likes of Ray Eames and Florence Knoll. In 1950 he began working for Knoll creating, among others, the now iconic "Diamond Chair" and the "Bird Chair". His work has been internationally recognized for it's forward-thinking approach and it's literal bending of both metal and rules set for Modern design and his work is on permanent display across the globe in such museums as France's Musée National d'Art Moderne. Knoll, now MillerKnoll, Inc., is an American company founded in 1938 that manufactures office systems, seating, storage systems, tables, desks, textiles, and accessories for the home, office, and higher education. The company is the licensed manufacturer of furniture designed by architects and designers such as Harry Bertoia, Ludwig Mies van der Rohe, Florence Knoll, Frank Gehry, Charles Gwathmey, Maya Lin, Marcel Breuer, Eero Saarinen, and Lella and Massimo Vignelli. Over 40 Knoll designs, including the "Diamond Chair", can be found in the permanent design collection of the Museum of Modern Art in New York City. With it's custom hand-made leather seat in rich Italian leather, iconic warped-screen frame and world-famous comfort this "Diamond Chair" is ideal for collectors and designers alike searching for an authentic, vintage Bertoia chair...

Bertoia Diamond Chairs, White, Set of Two, Welded & Painted Steel
By Harry Bertoia
Located in Bloomfield Hills, MI
SALE ONE WEEK ONLY Bertoia Diamond Chairs, White, Set of Two, Welded & Painted Steel. They are as elegant, strong and functional as when they were manufactured. The chairs will add a touch of class to any setting. Harry Bertoia's career began in the 1930s as a student at Cranbrook Academy of Art where he re-established the metal-working studio and later became head of the department before the school closed during WWII due to wartime restrictions on materials in 1943. During the war, Bertoia moved to California and is credited with developing new techniques for molding plywood with Charles and Ray Eames also from Cranbrook. Harry Bertoia is one of the many well-known artists and designers who attended The Cranbrook Academy of Art in Bloomfield Hills, Michigan, The school & buildings were designed by architect and faculty member, Eliel Saarinen who collaborated with Charles and Ray Eames on chair and furniture design. It is the country’s top ranked, graduate-only program in architecture, design and fine art. Each year, just 75 students are invited to study and live on the landmark Saarinen-designed campus which features: private studios, state-of-the art workshops, the renowned Cranbrook Art Museum and 300 acres of forests, lakes and streams, all a short drive from the city of Detroit. The focus at Cranbrook is on studio practice in one of ten disciplines including Architecture, 2D and 3D Design, Ceramics, Fiber, Metalsmithing, Painting, Photography, Print Media, and Sculpture. The program is anchored by celebrated Artists- and Designers-in-Residence, one for each discipline, all of whom live and practice on campus alongside the graduate students. Numerous creative artists who are alumni of Cranbrook include: Florence Knoll, Jack Lenor Larsen, Donald Lipski, Duane Hanson, Nick Cave, Hani Rashid, George Nelson, Urban Jupena (Nationally recognized fiber artist), Artis Lane (the first African-American artist to have her sculpture, "Sojourner Truth," commissioned for the Emancipation Hall in the Capital Visitor Center in Washington DC), Cory Puhlman (televised Pastry Chef extraordinaire), Thom O’Connor (Lithographs), Paul Evans (Brutalist-inspired sculpted metal furnishings), Eugene Caples (small bronze images/abstract), Morris Brose (Bronze Sculptures), Herb Babcock (blown glass), Larry Butcher (mixed media), Lauren Anais Hussey (Abstract), Andrea Eis (film, photography), Lilian Swann Saarinen (Sculpture), Douglas Semivan...

That open-ended experimentation led to the 1952 Bertoia Side chair, which was fitted with a fluid metal lattice that gave the seating an ethereal quality.
