Zer0-G Chair

I made a Zer0-G concept chair. My current chair is very uncomfortable and I imagined what a better chair would look like.

Any 3D modeling software or CAD. (I used Fusion360)

Draw the side profile of what you would like your chair to look like.

Use the extrude tool in order to make your sketch a 3D object.

For any details you may want to add, draw a sketch of it and extrude your sketch. Use tool such as chamfer or fillet to get any desired shapes.
