1, boss.
The head must be kept upright, and you can't lower your head or raise your head, so as to minimize the pressure on the cervical spine.
2, waist.
The most important thing about the waist is to have a support, so my suggestion is to buy a lumbar support. I think the lumbar support is two important points: one is big, and the other is hard material. My whole back can rest on it, and I feel very practical. It's harder. That's what you like. More effort can support your waist better.
3, ass.
The butt must be the back of the chair and the innermost part of the chair. Because the structure of our cervical spine presents an S-shaped curve.
4. feet and legs.
Both feet must be on the ground at the same time. Don't cross your legs or have other weird shapes. Therefore, there should be a chair with adjustable height, and the height of the chair should be adjusted to the joints of the painting to ensure that the soles of the feet are flat when sitting down.
Feature description
"Sitting posture" is not only a requirement for posture and etiquette, but also very important for the health of spine and body. Correct sitting posture can not only bring people a comfortable experience, but also minimize the impact on health.
When sitting, try to keep your back straight, avoid stumbling, avoid hunchback and chest, and protect your spine and back muscles while shaping a straight posture.
