The Nico Ergonomic Chair features a sophisticated dynamic support system that adapts to your needs. Its standout feature is the adjustable back curvature: tightening the backrest not only provides firmer lumbar support but also unlocks an enhanced recline range. When the curve is engaged, the chair offers four optimized locking angles at 109°, 118°, 125°, and 135°, delivering deeper relaxation alongside superior spinal alignment.
