Chairs play a very important role in the history of China. With the improvement of the quality of life and the deepening of the concept of health preservation, chairs gradually develop in a healthy direction. In recent years, ergonomic chairs have become popular in China and are loved by consumers. Nowadays, the ergonomic chair has been improved by scientists to become a multifunctional healthy portable chair, which can be adjusted according to personal comfort and can be used for both lying and sitting. Moreover, the design of the ergonomic chair reduces the compression area of the buttock and back, compresses the acupoints at the stressed parts, promotes the blood circulation of the buttock and back, and avoids the strain of the neck, shoulders and waist, which has a good health care function.

How to use the ergonomic computer chair correctly?

1, the correct height of the cushion should be adjusted so that your feet can lie flat on the ground and the thigh bending angle is 90.

2. The correct depth of the cushion should be from your hip to the innermost part of the cushion. Adjust the depth of the cushion appropriately so that the cushion can effectively support more than 2/3 of the thigh, and the bending angle between the thigh and the calf is 90.

3. The correct height of the handrail should be adjusted to 90 between the arm and the elbow, at which time the arm naturally hangs down without any sense of shoulder hanging. Long-term lack of support or poor support of the arm will cause shoulder pain or scapulohumeral periarthritis, which has a great impact on health.

4. How to correctly choose a computer chair suitable for the whole back should be the correct back pad angle? It is completely attached to the back pad, so that the back spine can be relaxed to a certain extent, thus effectively relieving the fatigue of the back spine and preventing the occurrence of chest and back pain.

5. The correct waist height should be adjusted to the position of the third, fourth and fifth lumbar vertebrae, because the weight of the whole person is borne by the lumbar vertebrae except the legs and buttocks when sitting, so the correct adjustment of waist height is helpful to prevent tendon or myositis, intervertebral disc herniation, spinal recession, lumbar muscle sprain, degenerative spondylitis, sciatica and so on.

6. When operating the depth adjustment of the seat cushion, the seat cushion will slide out by the power of the hip. At this time, the back needs to rely on a fixed cushion, so that the strength will be emitted from the buttocks. If the cushion is not locked, the back will lose the strength to rely on, resulting in the inability of the buttocks to exert force, and then the cushion cannot slide smoothly.

7. The correct angle of the armrest pad should be able to support your hand or elbow moderately anytime and anywhere. Without proper support for a long time, carpal tunnel syndrome and elbow joint syndrome are likely to occur, which is of course related to the protection of cervical vertebrae.

8. The correct headrest height should be adjusted from the third to the seventh section of the cervical spine, so that the cervical spine can be moderately supported, effectively alleviating cervical fatigue and preventing bone spurs or chronic spinal degeneration.
