Design of a CNC routed sheet good chair

A chair of acceptable comfort, requiring minimum material and labor, was made by developing a system of parts and joinery, cut from sheet stock, using only one tool-a 3-axis computer numerically controlled router. Comfort is achieved through ergonomic shaping of the chair components to embrace the geometry of the human body, and support several comfortable seating positions. All components were cut with a 3-axis CNC router using only one cutting bit. The joinery requires no additional hardware, glue or fasteners to hold the chair together. The final chair design requires 12.5 square feet of 1/2" sheet stock. Cutting time on the router is 1.5 hours, and assembly, which requires only a mallet, takes 0.5 hours, giving a total production time of 2 hours. Using Baltic Birch Plywood, the total material cost is $16.00. Using Oriented Strand Board, the total material cost is $2.88.
