What is lumbar support on an executive chair and why does it matter?

The lumbar region of the spine (L1–L5 vertebrae) has a natural inward curve that flattens and reverses under prolonged sitting without support — causing disc compression and muscle fatigue. An executive chair's lumbar support fills this curve, maintaining the spine's natural lordotic position. On high-quality executive chairs, lumbar height and depth are both adjustable. On entry-level models, lumbar is a fixed cushion. Adjustable lumbar is strongly preferred for users of varying heights.
