After a large number of cruel statistics came out, the national health department formulated a special standard: from primary school to high school, children should be equipped with 10 kinds of desks with different heights and specifications.
The height of the desk can be adjusted synchronously with the child's height growth, that is, it grows with the child. The desk should meet the daily learning needs of children, and it should be suitable for writing, reading, drawing, and computer desks. To achieve the four requirements at the same time, the angle of the desk must be adjustable.
The material quality of the desk should be excellent, environmentally friendly, scratch-resistant, wear-resistant, and the overall design structure should be strong.
The specifications of the desks and chairs for primary school students are generally 63 cm high, and the chair should be selected to 32 cm, which is more suitable for the proportion of the child's body, and for most primary school students, the chair of this height is more comfortable to sit on. When a child enters junior high school, the chair and table should be raised by 5 to 10 cm. Using ill-fitting tables and chairs, children are easily fatigued, reduce learning efficiency, and affect academic performance.
If the chair is too low, you can only stretch your neck, and if the chair is too high, you have to bend over. Only when the body, table, and chair are properly matched can the child's waist board be straight.
