Many young people and even teenagers have cervical spine problems of varying degrees.

The waist load of the four sitting positions of upright sitting position, relaxed sitting position, upright desk sitting position, and relaxed desk sitting position increases sequentially. The greater the anterior angle of the spine, the greater the load on the muscles and soft tissues around the lumbar spine, and the easier it isCause fatigue and even chronic damage to the soft tissues of the waist, especially the back. Therefore, it is best to choose a sitting posture with a smaller forward angle of the spine to prevent low back muscle fatigue and various chronic injuries.
