Dixon's favourite technique in the 1980s was welding and the frame of this chair is welded steel while the upholstery is made from rush. The rushwork here was done by a British basket-making firm. At this point in his career, Dixon did not use drawings, building the chair and altering and changing the design as it was developed in his studio. The name of the chair is a reference to its sinuous shape which is like the letter 'S'.
