For over two decades, the Vitra Design Museum has been making miniature replicas of milestones in furniture design. The Miniatures Collection encapsulates the entire history of industrial furniture design - moving from Historicism and Art Nouveau to the New Objectivity of Bauhaus and Radical Design, and from Postmodernism all the way up to the present day. Exactly one sixth of the size of the historical originals, the chairs are all true to scale and precisely recreate the smallest details of construction, material and color. The high standard of authenticity even extends to the natural grain of the wood, the reproduction of screws and the elaborate handicraft techniques involved. This has made the miniatures into popular collector's items as well as ideal illustrative material for universities, design schools and architects.

Harry Bertoia, who came from Italy, originally dedicated himself to sculpting. He created a series of chairs and seats using techniques he was familiar with from gold work and sculpting with iron wire. Until 1953 he developed these ideas together with specialists from the Knoll company until they were ready for mass production.

The structure of the Diamond Chair clearly separates the different functions of the chair: the transparent wire shell is bent out of a quadratic lattice into an organically shaped diamond like a net frozen in space, and the base of round iron embraces it like a polished diamond.

Bertoia considered his furniture to resemble his sculptures and explained: "In chairs many functional problems have to be solved first, but basically chairs are also studies in space, form and metal. On close inspection it becomes clear that they are mostly made up of air. Space flows right through them."

Each Vitra miniature is true to the original in construction and materials, and reduced in size on a scale of 1:6. Each miniature is packaged in a wooden box, accompanied by an informational booklet. Production notes: Each of the delicate objects are made by hand; on average, each miniature requires five hours of careful manual work. Ongoing quality control ensures that every miniature corresponds to its larger original in terms of finishing, details and materials.
