How to Build a Simple Chair for Schools or Homes in Disadvantaged Areas of the World Using Local Res

Communities in developing countries have limited budgets for education. Even though they may provide a school building, they often don’t have money to buy furniture to equip it. However, low-cost, durable, attractive school chairs can be produced in essentially any region of the world from locally available wood, wood residues, or semi-processed woody materials. This publication titled "How to build a simple chair for schools or homes in disadvantaged areas of the world using local resources and low-end technology" by Dr. Eva Haviarova and Dr. Carl Eckelman, describes the process for producing these durable chairs.

The chair described here uses round mortise-and-tenon joints that can be made easily—yet have the tolerance and quality of fit of chair joints made in a first-class furniture factory. Production requires just two tools mounted in a lathe, drill press, or custom-made machine—a drill bit and a hole saw. Other kinds of joinery (square mortise and tenon, dowels, etc.) require more involved processes and are much more difficult to produce accurately. Use of a shrink-and-swell fit (discussed later) allows a chair to handle extreme seasonal changes.
