The Knoll Diamond Chair is an sublime study in space, form and function by one of the master sculptors of the last century - Harry Bertoia. Like Eero Saarinen and Mies van der Rohe, Bertoia found elegant grace in an industrial material, elevating it beyond its normal utility into a work of art. Harry Bertoia’s wire chairs are among the most recognized achievements of mid-century modern design and a proud part of the Knoll heritage. This version comes fully upholstered in fabric.
