Aalto chair 69, designed in 1935, is one of Alvar Aalto’s favorite dining chairs. Also in the chair 69 he used the L-leg structure, which made it possible to attach the legs of the dining chair directly to the seat. Aalto chair 69 was originally designed by Alvar Aalto for the Viipuri Municipal Library. In 1927 Aalto won the planning competition for the library and the building was inaugurated in 1935. Besides planning the building, he also designed lamps, details of the interiors and furniture like the chair 69. The seat base and the backrest of this chair are wider and thus provide superior stability and everyday function.
