This swivel armchair is a re-working of the LC7, whose frame was in tubular metal, and was the work of Charlotte Perriand in 1927. It was later exhibited along with other furniture that Perriand co-designed with Le Corbusier and Pierre Jeanneret for the 1929 Salon d’Automne in Paris. The original design was executed in Vietnam in 1943, using the materials and crafts techniques available during that war-time period. The first model had three legs, with a fourth added later.
