The Model 3107 chair by Arne Jacobsen and produced by Fritz Hansen is one of the most popular chairs in Danish design history. It was designed using a new technique in which plywood could be bent in two dimensions. It has been produced exclusively by Fritz Hansen A/S ever since its invention in 1955. It is also the most copied chair in the world.
Being a "copy" itself contributes some irony to that fact. The chair, along with the Jacobsen's Ant chair, was, according to Jacobsen himself, inspired by a chair made by the husband and wife design team of Charles and Ray Eames.
The chair comes with a number of different undercarriges - both as a regular four-legged chair, an office-chair with five wheels and as a barstool. It comes with armrests, a writing-table attached, and different forms of upholstring. To some extent, these additions mar the simple aesthetics of the chair, while contributing with some practical elements.
The chair is widely believed to have been used in Lewis Morley's iconic photograph of Christine Keeler; however, the chair used in this photograph was in fact an imitation and not the original Jacobsen model.
