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 awanted to work for Le Corbusier, 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 became convinced to offer Perriand a job in furniture design, adding the Siège Pivotant to his collection.

The Outdoor Version

The outdoor version of the Siège Pivotant is made entirely from polished AISI 304 stainless steel. The internal structure and back of the seat are in pre-treated steel in an electroplating bath and finished in black. Details such as the silver welding and the use of black PVC foot ends, ensure maximum durability and reliability in all weather conditions. The cushion insert in water draining polyurethane, has been developed is designed to make water flow through, preventing stagnation and the accumulation of liquids, mould and unpleasant odours. The back inserts are in CFC-free polyurethane foam with water-repellent coating and the fabric uses a high tenacity polyester yarn, PVC coated. It is available in five colours.
