Ergonomic tables and chairs

Ergonomic tables and chairs-as the name suggests, are tables and chairs designed according to ergonomics, so that the use of tables and chairs as much as possible to adapt to the natural form of the human body, so that the people using the tables and chairs do not need any active body and spirit when working Adapt to minimize fatigue caused by using tables and chairs. According to a large number of data statistics, the country refers to relevant foreign standards, and the Ministry of Health formulates special standards (GB / T 3976-2014 school desks and chairs functional dimensions and technical requirements ^[1]

1. The chair seat is fixedly tilted backwards, which is not suitable for desk work and study. It will only make the spine more curved and the viewing distance is insufficient; (Figure 8)

2. One-sided emphasis on the angle change of the table, but the lack of angle coordination of the chair makes it difficult for people to truly achieve the purpose of raising their heads and chests. At the same time, because the arms were nowhere to be placed, they could only be placed on the table, causing the shoulders to be retracted and towering, which caused periarthritis; (Figure 9)

3. Although the seat back can be changed back and forth, it has no special significance for desk work and study;

4. If the height of the table and chair is arbitrarily raised and lowered by the child, the damage caused by too high or too low is greater than that which cannot be raised, which also increases the supervision of parents; (Figure 10)

5. The cushion is too soft and thick, lacking directional force, causing the lumbar vertebra to sink and bend, the waist and abdomen muscles are soft, the fat is accumulated, and the temperature and humidity balance of the skin is affected, which causes skin diseases and hemorrhoids, and hinders male sexual development; )

6. The lifting stroke of the table is not enough to provide a standing position, which will only make the spine more curved (Figure 12)

7, the arm can only be suspended, or can only be placed on the table, causing tension and fatigue of the shoulder and wrist joints, causing periarthritis and mouse hands (Figure 13)

8. The desktop material is too bright and bright, and the reflections and glare produced by it will stimulate the eyes.

9. The so-called posture correctors 1, 2 (support or tie the person's chest), although they can prevent the body from leaning forward, they force the cervical spine to be more curved and cause diseases such as the chest cavity and heart and lungs (Figure 14)

10. The so-called posture corrector 3 (supporting the person's chin), because the human eye cannot be parallel to the book, the head will inevitably get around the posture corrector to obtain images, which will cause crooked necks, high and low shoulders, and cross-eyes.
