ErgoHuman Gen2 is engineered with your total comfort in mind. Aesthetics, form and function are merged seamlessly to allow you to minutely adjust the chair, achieving unrivaled, ergonomic fine-tuning. Chair features a headrest, synchro-tilt mechanism with seat slider, forward tilt, tilt-tension control, lumbar-tension control and height-adjustable ratchet back. Single-lever control adjusts height, seat depth and tilt lock. Glass fiber mechanism allows smoother adjustment and precision. Matrex T168 mesh with 12-zone mesh support provides optimal breathability. Large, soft, padded arms pivot and adjust (height, width and depth). FPC non-petroleum frame is stronger and smoother than nylon. All-mesh chair is GreenGuard Gold certified.
