Where should my back support be on my chair?

Back support positioning revolves around the lumbar area, situated in the lower back region. Properly placed, the lumbar support should align with this section, offering a fluid, comfortable posture at the workplace.

In office chairs, this support region will typically be situated at the bottom of the chair's backrest, sitting slightly above the user’s belt line.


Office chairs equipped with proper back support significantly enhance comfort and productivity. The average backrest height falls between 32 to 34 inches, and the most imperative area to provide support is the lower back or lumbar region.
