Stool 60 is a three-legged stool designed by the Finnish architect Alvar Aalto in 1933. Its legs are moulded into an ‘L’ shape through a twenty-five-step technique patented by Aalto: thin slits are cut into one end of a piece of dried birch and are then filled with sheets of glued veneer; when heated, this layered composite can be bent into any angle. To finish the stool, the legs are simply screwed to the bottom of a round seat. Its three legs and minimal shape make the stool especially easy to stack, saving storage space for both manufacturer and owner.
One of many examples of bent-wood seating developed by Aalto, Stool 60 advanced the architect’s interest in furniture whose aesthetics emerged from contemporary manufacturing methods. Its distinctive pale-yellow wood is both structurally stable and visually warm, enriching the formal vocabulary of an internationalising early modernism. By 1935, Aalto began fabricating the stool with Artek, a company he co-founded with several collaborators, including his wife, the architect Aino Aalto. With many variations in colour and finish, Stool 60 is still in mass production today.
