The L1 Ergo UPGRADE 518 is a full-featured ergonomic office chair built around adjustability. It pairs a 2D headrest and 5-level backrest with dynamic lumbar support, a seat that moves in height and depth, and 4D armrests. A 135° recline and 4-level tilt tension round it out. It suits people who sit long hours and want to dial in fit rather than accept a fixed frame. Against simpler mesh chairs it offers more adjustment points, though the extra levers mean a longer setup and more to learn.
