Ergonomic chair sitting posture tutorial:
1. The correct seat cushion height must be adjusted so that your feet can lie flat on the ground, and the bending angle of your thighs is 90°.
2. The correct seat cushion depth should place your hips on the innermost part of the seat cushion, and adjust the seat cushion depth appropriately so that the seat cushion can effectively support more than 2/3 of the area of the thigh, and the bending angle between the thigh and the calf is 90°.
3. The correct height of the armrest should be adjusted to 90° between the arm and the elbow. At this time, the arm hangs down naturally, and it feels correct without any hanging shoulders. Long-term unsupported or poor support of the arm can cause shoulder pain or frozen shoulder, which has a huge impact on health.
4. The correct angle of the back cushion should completely attach the entire back to the back cushion, so that the back vertebrae can be relaxed to a certain extent, thereby effectively relieving the fatigue of the back vertebrae and preventing chest and back pain.
5. The correct waist height should be adjusted to the position of the third, fourth, and fifth lumbar vertebrae, because when the human body is in a sitting position, except for the legs and hips, the weight of the entire person is borne by the lumbar vertebrae. Therefore, the correct adjustment of the waist height helps prevent tendon or fasciitis, intervertebral disc herniation, spine sliding, lumbar sprain, degenerative spondylitis, sciatica, etc.
6. When operating the seat cushion depth adjustment, it is necessary to rely on the strength of the hips to slide the seat cushion out. At this time, the back needs to rely on a fixed back cushion so that the force is emitted from the hips. If the back cushion is not in the locked state, the back will be caused. The loss of the strength that it relies on causes the hips to be unable to exert force, and the seat cushion does not slide smoothly.
7. The correct angle of the armrest pad should be able to provide moderate support to your hand or elbow joint anytime and anywhere. Long-term lack of proper support on the hand or elbow joint can easily cause wrist tunnel syndrome and elbow joint syndrome. Of course, it is related to the cervical spine. Protection also has a certain relationship.
8. The correct headrest height should be adjusted to the third to seventh section of the cervical spine, so that the cervical spine can be properly supported, effectively relieve the fatigue of the cervical spine, and prevent bone spurs or chronic spine degeneration.
9. The correct adjustment of the elasticity of the back cushion should be based on the weight after the back is relaxed, to properly adjust the elasticity of the back. If the elasticity is greater than the weight of the back, it will show that it is difficult or difficult to recline, which will cause discomfort. , If the elasticity is less than the weight of the back, the feeling of insufficient support will be generated or the rapid backwards will cause insecurity.
