There are many reasons that affect students' academic achievement and health. One of the reasons is that school furniture is not ergonomic. Designed in this paper are student chairs and desks, which are height adjustable and inclinable, are suitable for the anthropometric characteristics of the students and which would ensure that students maintain their ideal body postures in design oriented classes, especially while making drawings. The student desk and the chair were designed in consideration of the anthropometric data obtained from the students. The height-adjustable seat can be used at three different heights according to the leg length of the students and the designed table can be used inclined. Ergonomically evaluation of the school furniture designed was carried out through RULA - Rapid Upper Limb Analysis. During the tests and the analyses, Digital Human Models (DHM) matching the anthropometric measures determined within the study were used. Risk assessments were conducted in this study with the help of the ergonomics analyses carried out with DHMs. In the RULA analysis, the limbs positioned in the ergonomic position were colored from green to red. As a result of the analysis, it was seen that the designed furniture had a better RULA score than the known school furniture.
