Abstract

BACKGROUND: Inappropriate design of chairs and disproportion with students’ body dimensions can influence their physical and mental health as well as their educational efficiency and concentration.

OBJECTIVE: The aim of this study was to examine the ergonomic status of commonly used chairs in Iran’s universities using combinational equations and anthropometric indices.

METHODS: Participants in this cross-sectional study were 166 students in Iran. Eleven anthropometric parameters of the students and nine dimensions in seven types of commonly used chairs in Iran’s universities were measured. Combinational equations were used to determine the fitness of the chairs.

RESULTS: There was a major mismatch between most students’ anthropometric measurements and the dimensions of the chairs. Backrest height and seat height were the best and the worst features, respectively, according to ergonomic recommendations for chairs. The recommended measurements of seat height, seat depth, seat width, desk height, desk width, desk length, backrest width, backrest height, and desk distance were 332, 420, 436, 245, 95, 511, 426, 550, and 281 mm, respectively.

CONCLUSION: None of the commonly used chairs in Iran’s universities were found to be a good fit to the students’ anthropometric dimensions. Therefore, in order to prevent inappropriate body postures, chairs designs have to reviewed, and made to fit with Iranian students’ anthropometric data. The recommended measurements obtained in this study can be used to design a suitable ergonomic chair to match with a high percentage of Iranian students.
