AI-assisted summary

Description from the seller

Harry Bertoia – Diamond Chair – Knoll – Vintage Design Classic

An iconic Diamond Chair, designed by the Italian-American artist and designer Harry Bertoia in 1952 for Knoll.

The Diamond Chair is among the most important furniture designs of the twentieth century and an exceptional example of American mid-century modernism.

With its characteristic diamond-shaped seat shell made from carefully formed and welded wire, Bertoia created a design that sits at the boundary between furniture art and sculpture. The transparent wire construction gives the chair remarkable visual lightness, while the organic lines and balanced proportions ensure a timeless appeal.

Bertoia approached furniture design from his background as a sculptor. His Diamond Chair is therefore not merely a functional seating piece, but also a spatial work of art that reveals a different pattern of lines from every angle.

Condition

This vintage piece is in good condition, with signs of wear appropriate to its age and normal use. The chair retains its characteristic design and authentic vintage look.
