Using pieces CNC-cut from 24mm and 12mm plywood, this stackable plywood chair is a prototype testing whether a chair can be produced from plywood where:

1. There are no nuts, bolts, screws, nails or glue

2. There are plywood surfaces curved through kerfing only rather than steam-bent plywood layers.

 

The chair uses dovetail shapes and use of a dovetail bit in the CNC milling in order to "pull" the kerfed surfaces into shape without the use of nuts, bolts, screws, nails or glue.

 

It was found, however, that it required too much force to slide the bent plywood pieces into place such that the dovetail shapes in the framework could grab it and keep it in shape.  The lessons learnt from this chair will be used in the next chair project.
