Steelcase International Asia-Pacific . Move your back.
Experts say the spine needs to move to help muscle ligaments and discs stay healthy.
Many chairs today encourage overall body movement, not spinal motion. Exercise your back from time to time by taking deep breaths or by arching your back. It is also recommended that you continually change your posture from time to time allowing for nutrients to flow to the discs in your back. Try not to hunch. You tend to hunch when you lean forward and when you lean back, letting your lower back sag against the chair.
