When the lever is pushed, the chair collapses and the cam shape rotates into a silicon rubber. A torsion spring then tries to push the wheel away from the silicon rubber, returning the chair back to it's initial standing position.
We initially designed the shape in 2D CAD, had the parts laser cut, then left it to our craftsmen to add the final tweaks to the cam shape,,, these tweaks allow the chair to raise slowly, like it's really Lazy!
