The design basis of the ergonomic computer chair is analyzed from the physiological characteristics of the human sitting posture.

The most natural posture of a person is the upright standing posture, and the spine is basically S-shaped when standing upright. But compared with standing upright, sitting posture is conducive to blood circulation in the lower part of the body, reducing muscle fatigue of the lower limbs, and sitting posture is also conducive to maintaining body stability.

However, because the pelvis tilts backward when sitting, the sacrum at the lower end of the back is also tilted, and the spine changes from an S shape (normal shape) to an arch shape, which puts a lot of pressure on the intervertebral discs of the spine and causes low back pain and other diseases. . Improper design of the seat surface of the chair will cause compression of the thighs, hinder the blood circulation of the lower limbs, and cause numbness of the lower limbs.

The intervertebral discs of the spine are under pressure, and incorrect sitting posture can not only reduce the load on the waist, but increase the load. Sitting with a straight waist helps to reduce the pressure in the intervertebral disc, but the muscle load increases. Sitting with a bent waist is good for muscle relaxation, but it increases the internal pressure of the intervertebral disc. Therefore, the inclination and shape of the backrest can affect the intervertebral disc and back muscles.
