What do desk and chair manufacturers tell you about the reasons for the low compliance rate of desks and chairs?
With the rapid development of science and technology, the raw materials for doors and windows of high-rise buildings in foreign developed countries have gone through three stages of "wood, iron and aluminium alloy". More than ten years ago, they all began to enter the era of using hard plastic instead of aluminium alloy. In recent years, scientists have designed a large number of plastic steel parts in cars, trains, ships and aeroplanes to replace wood, iron and aluminium parts, and their performance is far better than the former. Plastic instead of wood, plastic instead of steel, plastic instead of copper, aluminium instead of aluminium is not only an inevitable trend of technological progress, but also the way to the future development of China's manufacturing industry. Tables and chairs are no exception. Moreover, the future of desks and chairs can not only adjust the height, but also have a kind of connecting desks and chairs, consisting of height adjustable desks and chairs and spacing adjustable connecting plates. The desks and chairs manufacturer solves the problem that the existing desks and chairs for primary and secondary school students cannot be adjusted for table height, chair height and spacing between desks and chairs, suitable for use by students of all grades and sizes in spring and autumn, and the desks and chairs manufacturer can be adjusted according to each student's personal situation in order to fully meet the hygiene standards of the desks and chairs.
After an in-depth study, the desk and chair manufacturers found the following reasons for the low compliance rate of desks and chairs.
1, school bags can only be placed on the chairs
National standards for different heights of desks and chairs are based on the correct sitting posture. Correct sitting posture requires that the back two-thirds to three-quarters of the student's thighs should be placed on the surface of the chair, with the feet naturally flat on the ground so that there is no obvious pressure under the popliteal fossa.
In reality, however, it is often found that most of the chair surface is occupied by school bags and that only a third or less of the student's thighs are on the surface of the chair. The subjective perceptions of students should apply to seating in the upper grades.
2. Some desks and chairs are not up to standard
In fact, some desks and chairs in primary and secondary schools do not meet national standards. The main performance is to obtain more storage space by compressing the headroom under the table top so that it is less than the national standard. In this case, desk and chair manufacturers in order to allow students to sit down, it is necessary to lower the classroom chair or raise the desk.
3, some school tables and chairs configuration is unreasonable
At present, some regions tender for the purchase of a single variety of desks and chairs or unreasonable distribution. More commonly, adjustable desks and chairs of the same height range are purchased and uniformly distributed to high schools, junior high schools and primary schools, but primary school students are not tall enough to match these desks and chairs.
4. The height of school tables and chairs is not adjusted in place
Some schools do not personalise their students' desks and chairs according to the changes in their annual physical heights, and some schools adjust the height of their desks and chairs not according to national standards but according to students' preferences.
