Description

Posture Correction Chair

This creation is a sitting posture correction chair, especially a sitting posture correction chair used to correct the user's sitting posture.

In order to handle affairs conveniently, people usually adopt a more relaxed sitting posture in their daily life, which leads to modern people sitting most of the time in a day. The posture adopted when sitting for a long time will not only affect the bones and muscles of the human body, but also even affect the digestive system, respiratory system or circulatory system in the body. Therefore, whether the sitting posture is correct or not is closely related to the health of the human body.

When people sit, they often tend to hunch their backs or tilt their necks forward. However, when the body is hunched, the weight of the upper body is concentrated on the lumbar spine, and at the same time, the space in the chest and abdomen is reduced, affecting the respiratory system in the chest and the digestive system in the abdomen, which in turn leads to related diseases. In addition, when the neck tilts forward, it increases the burden on the cervical spine, and at the same time, the muscles and ligaments in the neck and shoulders are tense, resulting in shoulder and neck pain.
