CNC is an acronym for 'computer numerically controlled'. In this case its a machine that cuts away timber in layers. Its a reduction of material like a sculptor who removes the outer layers of material to reveal the shape.
This stool is a very sculptured shape that starts out as rectangular blocks of wood. Through a complicated and time consuming process the code that directs the machine is generated from a 3d virtual model. This stool takes a 3 axis CNC router machine to the limits of possibility and involves machining the parts from different angles to achieve the final result.
The legs are held into slots underneath with magnets and can easily be removed. This also means the stool can be more compact for shipping.
The design of this stool ensures water cannot directly enter into the joints, and will flow out of the upper surface, so it can be exposed to periodic wet conditions.
I can make pale, red, and black versions. The height and length of this stool is 450mm.
