The Fractal Chair (1x114)

Air date: May 18, 2023

I have recreated a "fractal" chair based off a patent from 1913. Similarly to the "fractal" vise that I previously restored, this chair uses the same series of pivoting sections to fully adapt to the shape of someone sitting down. The original patent can be seen here: https://patents.google.com/patent/US1... I used the original patent explanation as best I could to help design the function of the chair which uses stacked tongue and groove steel plates that interface with each other through a series of ball bearings that provide the movement. The design was fully realized with the help of Josh Fick, who digitally created all the pieces needed to be cut with a fibre laser.
