This mid-back office chair features a durable polyester mesh backrest with a curved design that contours to the spine’s natural shape, while a lumbar support system provides continuous lower back reinforcement. The seat cushion has been upgraded—widened and thickened—to offer a softer, more comfortable seating experience. Ergonomically designed armrests support the arms and help alleviate fatigue after long periods of work. The chair rests on a sturdy nylon five-star base equipped with smooth-rolling casters and a certified steel gas lift, ensuring excellent load-bearing capacity. It supports adjustable seat height and backrest recline; a push-pull lever allows for tilting or locking at various angles, while a tension knob adjusts the recline resistance to suit users of different weights. Ideal for daily office use, it is easy to assemble and boasts a stable, reliable structure.
