Abstract
Background: Proper designing of chairs based on ergonomics increases efficiency, promotes quality of education, leads to correct posture in students, and reduces risk of musculoskeletal disorders. Objectives: The aim of this study was to design and develop an ergonomic chair, based on anthropometric data of students in educational settings. Methods: Anthropometric parameters were obtained from a stratified-random sample of 207 students. The data were analyzed using the SPSS 20 software, and the results were extracted as mean, standard deviation, and percentiles. The chair was planned in the CATIA software and developed by a three-dimensional print. Results: In this study, an ergonomic chair was designed based on anthropometric data from students. The seat height, depth, and width of the chair were determined as 44 cm, 42 cm, and 42.15 cm, respectively. The height of the desk was adjustable in 19 to 29 cm, and the depth and length of the desk were considered as 51 cm and 65 cm. The width and height of the backrest were also 54 cm and 44 cm, and the backrest angle was adjustable in 95° to 105°. Conclusions: An ergonomic chair with adjustable parts was designed to achieve a well-match between anthropometric characteristics of students and the furniture. Such chair can reduce musculoskeletal disorders in students. Some ergonomic characteristics of this chair include adjustability of footrest, backrest, armrests, and desk. A chair with such characteristic can be used by many students with different body sizes.
