Option 8: Lumbar Selection

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.
