Quick Links

As voluminous as it is comfortable, Armchair 400 was created by Alvar Aalto in 1936 for an exhibition at the Milan Triennale, where it was promptly awarded a prize. The chair owes its nickname “Tank” to its distinctive wide and sturdy armrests made of form-bent birch lamella and to its robust upholstery. The springy cantilevered frame offers a flexible, comfortable seat. A favourite since the 1930s, Armchair 400 remains effortlessly modern and can be upholstered in any material.

Armchair 400 has appeared in zebra-patterned fabric ever since the 1930s.
