L213 armchairs were chosen for the Auditorium of the Austerlitz office complex in Paris, part of a vast urbanisation plan (the largest since the Haussmann era) spanning a 3-km-long area that separates the Austerlitz Bridge from the eastern boulevard. The offices, designed by Ateliers 2/3/4/, reinvent classic Parisian architectural style and are home to various functional settings, including a 140-seat auditorium equipped with L213 armchairs that, like the rest of the room, boast a meticulous colour design. Upholstered in Kvadrat Hallingdal 65 fabric in two different shades of yellow, the chairs, arranged in straight tiered rows, have straight side panels, a writing tablet with anti-panic motion, and an electrical system. The gravity-driven tip-up seat has a braking mechanism. The seatbacks, which usually reach down to the floor, are shorter here, adapted to the height of the tiered steps and shaped to match the side panels. The seat and row numbers embroidered into the fabric demonstrate the close attention to detail.
