What is the Siège Pivotant?

The Siège Pivotant is a small armchair designed by Charlotte Perriand in 1927 for her flat sited in place Saint-Sulpice, Paris. It was first exhibited at the 1928 Salon des Artistes Décorateurs in the Salle à Manger 28, and subsequently at the 1929 Salon d’Automne, when it was integrated within the LC Collection, the collection co-signed by Le Corbusier, Pierre Jeanneret and Charlotte Perriand.

When was the Siège Pivotant conceived?

Only two years after graduating, Perriand renovated her apartment into a room made of aluminium, glass and chrome. She then recreated the design of the “Bar sous le toit” (the bar under the roof) at the 1927 Salon d’Automne. It was shining with gleaming aluminium and nickel-plated surfaces, leather cushions and glass shelves. At the time the press highly praised Perriand and addressed her design as a great success.

But the designer was not satisfied, she aimed at working for Le Corbusier and pursue serial production and low-cost housing, but when she applied to work at Le Corbusier’s studio in 1927, she was famously rejected with the reply “we don’t embroider cushions here”. Yet a month later, Le Corbusier visited her show at the Salon d’Automne, where the Siège Pivotant and the Bar sous le toit were still exposed, and he became convinced to offer Perriand a job in furniture design, adding the Siège Pivotant to his collection.
