Abstract
In the school space, there is a need to provide tables and chairs that support students in maintaining the optimal learning status. Desk and chair products for students, particularly for high school students, need to conform to ergonomic principles to prevent musculoskeletal diseases in schools. This study reported the average body size in standing and sitting positions of 11th grade students of both men and women aged 16 - 17 years old in Ho Chi Minh City in 2023. The article also provided specifications for lagerstroemia wood and rubber laminated wood which were selected as materials for the design of tables and chair in this studys. From the collected data on student body dimensions, combined with ergonomic parameters and relevant regulations issued by the Ministry of Health, the author designed a set of tables and chairs for high school students - grade 11 with desk size of 1200 x 450 x 710 mm and single chair with dimensions of 400 x 400 x 850 mm, seat height of 410 mm. As a result, a product model was designed, the manufacturing process was proposed, and a trial production of the table and chair set was conducted.
