In the late 1920s, architect and designer Alvar Aalto began experimenting with bending wood. In collaboration with furniture manufacturer Otto Korhonen, the Finnish master developed a ground-breaking process that resulted in the L-leg. To create the L-leg, cuts are made in the end of a piece of wood, with the slits extending just below the level of the planned bend. Bar stool 64 Configurable by Artek, embodies exactly that.
