The other day I posted a more complex design for this flat folding chair. That design has more curved corners making it a a bit less angular. This design is bare bones and shows the simple concept better. In a nutshell you take a 2′ x 3′ piece of furniture grade plywood and turn it into a chair by cutting it up and add two piano hinges.
The trick to making it work is the placement and size of the locking notches. These keep the chair open when folded into place. When the chair is not in use it simply folds flat and is stored away. It takes up slightly less storage space than a normal folding chair, and looks a lot cooler 🙂
I plan to build this chair soon and will post a how-to video when I do. So be sure to subscribe by email to get that update.
