Bentwood, bent to a right angle
The L-leg is Artek's own joint: solid wood bent through a right angle so the leg meets the seat directly. It is the detail the Stool 65 is built on, and the reason the piece reads as one object rather than a seat on a frame. Aino and Alvar Aalto designed it for Artek in 1935. These examples were produced in Finland in the 2010s.
