Adolescence is a period of long body, and the appropriate size of student desks and chairs is conducive to the healthy growth of students. If the size of students' desks and chairs is not suitable, it will have a negative impact on the well-being of students. Too high desks and chairs will cause students' glasses to be too close to the desktop, resulting in visual impairment.

Too low desks and chairs will make students unable to hold their chest up when they are sitting, resulting in a curvature of the spine. The following aspects should be paid attention to: the national standard size of student desks and chairs. The government appropriately allocates financial funds to transform school desks and chairs, and purchase different types of desks and chairs according to the height of students.

　　Nine-year compulsory education schools should gradually prepare "adjustable" desks and chairs. For schools with financial resources, at least two different types of desks and chairs should be provided in each classroom. The competent education department should take the improvement of school desks and chairs as an important part of the routine management of school education, stop supervision and assessment, and notify those that do not meet the norms.

　　It is recommended that the height of desks and chairs be adjusted once or twice every semester to accommodate the monthly increase in the height of primary and secondary school students. The heights of desks and chairs for students of various models are different from international standards, and the height of the seating surface is 20mm and 10mm lower. The size of desks and chairs in primary and secondary schools: desktop width (left and right direction), from the original 550mm~600mm (single use) and 1000mm~ 1200mm (for double use) was revised to 600mm and 1200mm respectively.
