Designed by Alvar Aalto for Artek, the Armchair 402, also known as Atelje, has a more lightweight structure than Aalto's famous Tank chair. Moreover, the seat height is five centimeters higher than in the Tank chair, giving the Armchair 402 a larger use range. The flexible wooden frame makes the armchair extremely comfortable, following the movements of the sitter. The armchair 402 is one of those pieces of furniture introduced by Alvar Aalto in 1933 in London at the Fortnum & Mason department store's exhibition. The classic armchair is available in several upholstery options.
