The “Fractal” Chair

This video may be from 2023, but, we’re totally ok with that. Hand Tool Rescue built this fractal chair based on a 100+ year old patent and honestly, I’d to try it out myself.

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 joshsfick who digitally created all the pieces needed to be cut with a fibre laser.

Fractal chair or not, if you find yourself slumping while you sit maybe build yourself a Circuit Playground Slouch Detector
