Why don't the desks at school tilt?

Some experts have studied it. I still remember that in junior high school, it was inclined and could lift the lid.

Exposing six major crimes of secret study table

1, hurting people: 12 degree slope design is seriously unreasonable, without any scientific basis, just a selling point to fool people. Just like a flat table, it makes people adapt to its unreasonable state and is harmful to physical and mental health. The state stipulates that the desktop is infinitely adjustable at 0- 12 degrees.

2. Harmful to people: It is said that it has the dual-purpose function of plane and inclined plane, and the height difference between the two states is 12 cm, which is more harmful to use, and children are more prone to myopia and hunchback.

3. Illegal: 12 degree study desk slope, leveling method or structure with three main functions of height adjustment seriously violate the national standards for desks and chairs. Parents who can overturn my point of view will get a reward of 50- 12000 yuan (the right of interpretation belongs to the center).

4. Devaluation: More than 80% of children use flattening function to depreciate by more than half. If it is not adjusted in time, it will do more harm to children!

5. Backwardness: Inclined tables were used in primary and secondary schools and universities in the forties and fifties, but they were gradually eliminated because they were found to be harmful to the fixed inclined plane.

6. Deception: The manufacturer boasts that the study table has the functions of correcting sitting posture, preventing camel and protecting eyes only by relying on an inclined plane; Also said that China famous brand, produced in big cities, are actually fake. Learning desks, a small industry, have no brand at all, and are generally produced by individual manufacturers in remote rural areas.
