What type of lumbar support is most effective for lower back pain in an ergonomic chair?

Adjustable-depth lumbar support is more effective than fixed lumbar for lower back pain because it lets you push the support into exactly the right position for your lumbar curve. Fixed-depth lumbar is a compromise that fits some users well and others poorly. Dynamic lumbar support (which moves with your back as you shift posture) is clinically superior for users who change postures frequently. Look for height and depth adjustment as the minimum; height-only adjustment is better than nothing but still a compromise.
