Background: Sitting for long periods of time is a part of the illness, which can happen in the workplace and the lack of attention to the ergonomic principles causes musculoskeletal disorders such as backache, pelvic ache, shoulder ache, elbow ache, arm ache, wrist and ankle ache, and muscle aches in the other parts of the body. The present research was carried out according to the ergonomic principles and designs, in order to design an ergonomic chair, suitable for the computer users in the monitoring room of one of the industries in the Mazandaran province.
Methods: The participants in this study included a total of 32 male staff from the monitoring room of one of the industries in the Mazandaran province. A total of 24 anthropometric parameters were measured from the body of each of the subjects, sitting in a vertical position on an adjustable chair, using anthropometric calipers and meters and the data were analyzed with the Excel and the Minitab statistical programs.
Results: The mean age of the subjects was 42.59  ±5.34 years and the 5th, 25th, 50th, 75th, 90th, and 95th percentiles of their anthropometric dimensions and Pearson's correlation coefficients were obtained to design the height, the depth, the height, and the width of the ergonomic chair. All parts of the chair had two degrees of freedom. The neck and back supports, adjustable for this type of chair were designed specifically. Also, using MIT standards, the level of seat compressibility was measured to be 4.26 cm, based on the 95th percentile weight.
Conclusion: Considering that other countries design and produce suitable chairs, focusing on the anthropometric characteristics of the individuals, studies, similar to this research could be recommended in the different parts of the country, in order to design and produce appropriate chairs for the physical dimensions of the people and their needs.
