The existence of ergonomic training tools and devices improves the educational quality and convenience of students. Non-ergonomic training tools also cause musculoskeletal disorders in students and as a result, they will be less efficient. The purpose of this study was to examine the suitability of the seats available with the body dimensions of the male undergraduate and master’s students of Qom University of Technology. In this research, 60 male undergraduate and master’s male students of Qom University of Technology were selected randomly and 18 physical dimensions of them were measured by an anthropometric calliper with an accuracy of 0.1, 0.05 meter, and also seven important parts of the seat affecting on the body's posture were measured by the meter. Also, feeling or not feeling pain in the 8 parts of the bodies of these students and their feelings about the cause of the pain were asked by questionnaires and for data analysis, was used the SPSS version 22. The height of the seating area was almost appropriate. The length and width of the seat area and the width of backing was smaller than the optimal sizes. The height of the chair elbow was shorter than the optimal amount. The length of chair elbow was suitable, and the backing height from the seat area was not suitable. Only the height of the seat area and the length of chair elbow are somewhat appropriate and the rest of the seat parts are not proportionate to the students’ physical sizes. There was a significant difference between the parameters of undergraduate students and the master's students.
