1. Head: The height and rotation of the headrest can be adjusted, allowing the user's cervical spine to fit the headrest naturally, standardizing the sitting posture of the sitting person, and resisting office enjoyment. The best position is when the height of the headrest fully supports your cervical spine.
2. Chair back: The best support position for the waist is the third and fourth spine. The entire chair back can be adjusted in height, which can easily meet the needs of different users and reduce most of the human body weight on the lumbar vertebrae.
