What is a tension-adjustable mesh back on an ergonomic chair?

Tension-adjustable mesh backs allow the firmness of the mesh panel to be tuned to the user's weight and preferred support level — preventing too-stiff or too-soft back support for users at different ends of the weight range. High-quality tension-adjustable mesh maintains its calibration over years of use without sagging.
