Choose products that align with ergonomic principles. Generally speaking, the standard for a children's desk is 1.1-1.2 meters long, 0.76 meters high, and 0.55-0.6 meters wide; The height of the chair surface is 0.4-0.44 meters, and the overall height does not exceed 0.8 meters, which can fundamentally meet the needs of school-age children. This height is not very suitable for high school students. The design height used for lifting desks and chairs has been adjusted accordingly to meet the mainstream height requirements of the application group, in order to maintain students' spine and avoid myopia. I won't feel tired even after using it for a long time.
