Designing Ergonomic Furniture Based on Students Anthropometry attributes; Collage of Agriculture and Natural Resources, University of Tehran

Background and Aim: A well-designed desk and chair, in addition to proper learning, can prevent changes in the userchr('39')s physical form. Therefore, this study aimed to determine the anthropometric characteristics of students in the College of Agriculture and Natural Resources located at the University of Tehran to design an ergonomic table and chair. Methods: In this research, 18 anthropometric characteristics including the popliteal height, knee height, shoulder height, eye height, sitting height, elbow support height, elbow height, knotted elbow length, hip-popliteal length, hip-knee length, thigh thickness, abdominal depth, chest depth, hip width, shoulder width, the transverse width of the elbows, height, and as well as weight for 260 students (130 girls and 130 boys) aged 18 to 35 years were investigated. To collect data, an anthropometric chamber and chair were used. Finally, according to the measured physical dimensions of the students, the Dimensions of ergonomic table and chair were calculated and designed according to the INSO 9697-1 standard. Results: Anthropometric dimensions of students were obtained through mean, minimum, maximum, standard deviation, mean, and the percentile value of 2.5 to 97.5 using SPSS version 20 software. The results showed that the age of the user does not have a significant effect on the size of the table and the chair. Also, the results showed that there was a significant difference in popliteal height between girls and boys. Conclusions: Considering the difference in dimensions between female and male students, it was found that the popliteal height in the percentile of 5 for boys is 4 cm more than girls. Therefore, using measured anthropometric characteristics, the dimensions of the chair and table ergonomics were designed in two sizes.
