This office chair features a dual-density foam seat cushion—a firm bottom layer for support and a soft top layer for comfort—helping to relieve hip fatigue during long periods of sitting. The curved backrest utilizes high-density mesh to promote airflow and provide lumbar support, encouraging healthy posture. The armrests can flip up 90 degrees, allowing the chair to be tucked neatly under the desk to save space. It offers adjustable seat height and a recline function—a control lever allows you to switch between upright working and relaxed reclining modes. The chair features a stable base structure and a certified gas lift cylinder for reliable weight-bearing capacity. Easy to assemble with clear instructions and a full set of hardware included; suitable for home offices and various work environments.
