403 Hallway Chair by Alvar Aalto

A ‘403’ hallway chair designed in the 1940s  by Alvar Aalto and produced by Finmar in Finland, produced from 1940  to 1950, in birch ply.

The original design for Paimio Sanitorium.

This later variation and more well known model encompasses all of Aalto’s vision of simplistic form as well as economy when produced.
