The desk-and-chair and chair-with-mounted-desktop furniture are widely used in the classrooms of Bangladeshi universities. However, an anthropometric survey showed that the fixed-type and side-mounted-desktop-chair used by university students in Bangladesh were not manufactured according to ergonomic considerations. The study evaluated the potential mismatch between university classroom furniture dimensions and anthropometric characteristics of 500 Bangladeshi university students. Fifteen anthropometric measurements and nine dimensions from the existing classroom furniture were measured and then compared together to identify any potential mismatch between them. The paper showed the variation between the anthropometric measurements of students and the dimensions of existing furniture. The results indicated that the seat height of both desk-and-chair and side-mounted-desktop-chair was high, while the desk height of desk-and-chair was high and that of side-mounted desktop chair was low for the students. The paper also recommends the furniture dimensions for both types, which are ergonomically fit.
Ergonomics is the science of human fit. It decreases fatigue and discomfort through product design. Its aim is to achieve coordination between man and machine. Application of ergonomics in the design of office furniture, by taking into consideration, how the products can be designed to fit the people that are using them. This thesis includes the problems faced by the students of Shahjalal University of Science and Technology, Sylhet, Bangladesh, while using the tabloid chair, designed earlier. Our objective is to identify ergonomic problems and the effects of using the tabloid chair that was design earlier. A survey was conducted on 100 students who took part in the previous tabloid chair design and have used the tabloid chair that was designed earlier for at least one hour at a time. This survey mainly focuses on the discomfort of the users. The results show that 14, 16 & 23 of the users felt discomfort at their neck, lower back & shoulder respectively. A new design was proposed for tabloid chair, by analyzing the survey results and using anthropometric data taken from 150 students who took part in the previous study. So the users may not face further problems. Taking cost of materials and other factors into consideration a tabloid chair was fabricated using ergonomics design concepts. Then, a comparison was done between the fabricated tabloid chair and the existing tabloid chair, which is shown in the final chapter.
Ergonomic design of classroom furniture for university students of Bangladesh

This study has been carried out to evaluate the number of mismatches between secondary girl student's anthropometry and existing furniture dimensions in Bangladesh. In this study, 375 students (girls) are in classes 6-10 in the age group between 10-15 years that have randomly selected from three secondary girl schools in Bangladesh. Twelve anthropometric measurements and seven existing furniture dimensions were taken to find out the possible mismatch. A defined match criterion equation used to determine the mismatch. Various researchers gave these equations. The result indicates that there is a significant mismatch between anthropometric measurement and furniture dimensions. The highest mismatch percentage for seat height is about 90% for class 9. Therefore, 90% of girls use the seat that is too high (high mismatch). Mismatch percentage for seat depth is 100% for all classes. As a result, seat depth is so small for all students. Seat width is 100% for class 8 and 60% for class 9. The desktop height is about 100% mismatch for all classes. This paper also proposes dimensions for new furniture. The new furniture improves the match percentages from 50% to 100%.

Engineering Science and Technology, an International Journal, 2017
This paper presents anthropometric measurements regarding engineering students in India. Health survey (ergonomic assessment) was carried out to know the health status of all students who have been using poorly designed furniture. The data were measured with the help of various tools. After data collection and analysis, authors came up with exhaustive dimensions for designing adjustable classrooms furniture. Dimensions recommended include; bench surface height, bench depth and width, back rest width and height, backrest angle, desk height, desk depth, width, and desk angle. Therefore, an implementation of these data will help to create comfortability, safety, well-being, suitability, reduce Musculoskeletal disorders, and improve performance of students in terms of attentiveness. Also, it is highly recommended to consider requirements from students in designing classrooms furniture and conduct seminar or workshop to educate students regarding the negative impact towards adapting poor posture in the long usage of classrooms furniture.

Health Scope, 2018
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.
