If students learn desks and chairs inappropriately, it will bring many problems, such as myopia, excessive curvature of the spine, and even hunchback. If you bend your body to write and read for a long time, it will also affect lung development and cardiopulmonary function, resulting in small chest and small vital capacity.
The school students’ learning desks and chairs do not match their height, which has become the primary factor causing students’ myopia, oblique shoulder, shrug and hunchback.
The height specifications of 10 types of desks and chairs are determined according to their height. The height span of desks and chairs of each model is 14 cm, with the minimum of 49 cm (in the lower grades of primary school) and the maximum of 76 cm (in the middle schools). Suppose that the students are 130 cm tall, the table top should be 55-58 cm, and the sitting height should be 30-32 cm.
We should customize desks and chairs according to the spring and autumn and physical characteristics of primary and secondary school students, and put students’ health first.
