Design Image: 

Four CNC cut plywood pieces, two ends and two center sections. Each section is held together with rod and spacers for easy assembly and disassembly. The seat back and seat are produced the same way, from CNC cut plywood and notched into the center sections. The edges of the outside pieces are painted red, or another desired color, to emphasize the cut shapes. Since the whole stool is CNC cut the lengths can be changed easily for a smaller chair, and the graphic breakup moved around for a change in style.
