I was skeptical of the “dynamic auto-chasing lumbar” marketing claims until I sat in it. The lower backrest sits on a flexible mechanical spring. When you lean forward to inspect a line of code, the lumbar pad pushes forward gently to meet you. When you lean back to think, it pivots smoothly to cushion your lower spine. The mesh is surprisingly springy and supportive without creating that trampoline bounce. My only minor gripe is the armrest height range: if you are over 6-foot-2 with a tall torso, you might wish the armrests rose another 1.5 inches higher to hit your desk surface flush.
