The present paper focuses on construction of school seats for developing countries from locally available resources using the local industry and low-end technology. Aim of the work is experimental assessment of mechanical properties of joints flexion in angular plane. Furthermore work considers assessment of joint firmness and comparison between various joint types. Paper encloses the review of various joint manufacturing designs (tenon and mortise), which were proposed for its suitable mechanical properties and simplicity of manufacturing. Designated joint type is easiest form of joint construction and technologically feasible for chair manufacturing. The joints were constructed from fir wood. Further the work introduces design of simple seat construction made from massive wood material manufactured by low-end technology with regards to achieving the due specifications. The task of this work is to design the viable manufacturing process of seats and chairs from raw wood and scrap material. Essential part of work is also manufacturing of seat prototype and simplified model of proposed mortise and tenon drill.

Keywords: bending test, furniture construction, manufacturing technology, tenon, mortise, transversal plane
