This design can be taken apart for easy storage. It has a nice smooth feel to it and curves to fit the shape of your body. Very comfortable especially if you have a cushion like mat between you and the chair.
The top layer of the chair is made of lots of fin ply wood glued together and bent round a jig as shown in the pictures, I repeated this step a few times until It was strong enough not to brake.
A fun project,it was a little difficult to build but worth it.
