Thesis is focused on design of production, material specifications and construction technology simplifications of school chairs and seats for developing countries. The use of locally available materials and equipment of local industry with application of low-technology manufacturing processes are emphasized. In developing areas this functional school furniture represents the basic comfort for pupils and facilitates the learning process. The thesis consists of three parts. The first part is focused on and deals with experimental assessment of mechanical parameters of various rectangular joint designs. In this case joints are stress-loaded in transversal direction. The second (practical part) of the thesis deals with designing the functional shape of seats with use of joints described and tested in the first part. The third part of thesis deals with manufacturing of designed chair model due to specifications mentioned in first part of thesis and also with design of simple tool for manufacturing the joints with low-end and low-cost technology. Further the thesis introduces my own 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 thesis is to design the viable manufacturing process of seats and chairs from raw wood and scrap material. Essential part of thesis is also manufacturing of seat prototype and simplified model of proposed mortise and tenon drill. The thesis encloses the literature overview, experiment methodology, description of potentially usable and really used materials. In last chapter the testing results are summarized and the sample of manufacturing is documented.
