As one of many seats designed by Harry Bertoia for Knoll International from filigree steel wire mesh, the Diamond Chair from 1952 is perhaps the the most refined. And certainly the most successful member of the collection. Equally as impressive as the chair's legendary diamond form is the design, based as it is on a highly complex process in which the steel wire is hand drawn and welded.

Design Story

The sculptor and designer Harry Bertoia developed during the 1950s various furniture designs for the American manufacturer Knoll International. The most successful of these designs is without question the Diamond Chair - a work so successful that on account of the resultant royalties Bertoia could henceforth focus exclusively on his sculptural works. Woven, more or less, from a filigree metal fabric the minimalist Knoll Diamond Chair is reminiscent of some of Harry Bertoia's sculptural work - not just in terms of material and form but for all in the way it is part of what Bertoia explains, as his "studies in space, form and metal". As an object in its own right the transparent Diamond Chair has an almost sculptural presence and thus sets a clear accent in any room or space. Today Knoll offers the Bertoia Diamond Chair with a frame made of steel wire and with welded metal shell in different versions and with cushions in three different colours.
