An astounding study in space, form and function, the Bertoia Diamond Chair takes industrial material and elevates it beyond its normal utility.

Product Story
The Bertoia Diamond Chair is an astounding study in space, form and function by one of the master sculptors of the last century. Like Saarinen and Mies, Harry Bertoia found sublime grace in an industrial material, elevating it beyond its normal utility into a work of art. Bertoia’s wire chairs are among the most recognized achievements of mid-century modern design and a proud part of the Knoll heritage.
- The artistry of sculptor Harry Bertoia shines through in the space-occupying form and criss-crossing internal connections.
- The base includes plastic glides to protect floors, and a stamped Knoll logo to ensure authenticity.
- Also available in other finishes, fabrics, and fully upholstered. To enquire please contact our in store team, or advice line: 0333 121 1915, Option 1.
