It's no exaggeration to say that most of the day's work for students or office workers is to sit in a chair, and most people, not just the above-mentioned categories, live their entire lives for at least 20 years. In particular, depending on the occupation, you may have to sit in a chair for the rest of your life.

Furthermore, unlike the past, where there was a lot of external activities such as high school fever and long hours of computer use, body shape imbalances in which the spine and pelvis are twisted are different. It begins around the age of three, and studies show that it can be severe in female students and that this disparity will continue while tall, so children's imbalances can affect developmental growth if not managed early, and even after adulthood. You won't have a straight and beautiful body.

As the chair is so close to human life, the effect of sitting on the chair will have a great impact on the body, and as mentioned above, if the posture is not correct, it will easily fatigue and cause body pain such as stiff shoulders. Bad posture can lead to body imbalances, such as malformations of the spine.

Accordingly, in recent years, chairs have been developed to prevent malformations of the spine due to incorrect sitting posture, and most of these posture correction or body correction chairs are focused on the back structure supporting the user's back.

However, a chair having a backrest structure and a characteristic structure may have an effect such as posture correction when the seated person is completely leaning on the backrest.

Looking at the usage behavior of the users sitting on the chair to work, most of the users maintain a state in which the upper body is slightly inclined forward, there is a limit that can not enable posture correction or body correction in this use state.

In particular, if the upper body is kept in the forward state for a long time, all the loads are concentrated on the waist, making it easy to feel tired, and incorrect posture, which may cause scoliosis.
