What is dynamic lumbar support on an ergonomic chair?

Dynamic lumbar support moves with the user as they shift posture, rather than remaining fixed in one position. Static lumbar is fixed once adjusted — it provides support in one posture but disengages when you lean forward or shift. Dynamic lumbar uses a spring-loaded or flex mechanism to follow the lower back's movement, maintaining constant contact throughout the range of natural seated motion. It is a feature of premium ergonomic chairs and is particularly beneficial for users who move frequently.
