Option 6: Lumbar Selection

The height and shape of the lumbar support should coincide with the lumbar curve ("the small") of the user's back. The support should be firm, but not cause localized pressure points.
The adjustable lumbar option on Office Master Chairs is a knob that changes the firmness of the lumbar support. Also most Office Master Chairs have adjustable height backs, allowing users to find the correct lumbar support position for them. LUM - Lumbar Support with adjustable Knob.
