The Black High-Back Split-Back Ergonomic Office Chair with Retractable Footrest, model ERG-SBFR-001, presents a sleek, professional all-black profile defined by its distinct split-back structure and coordinated fixed armrests. Its five-star nylon base supports a balanced, stable layout, with smooth PU casters fitted to each leg, and a contoured headrest positioned at the top of the tall backrest to complete the streamlined, functional silhouette that blends seamlessly into formal and casual work environments alike. Constructed for long-term durability, the chair features a breathable high-tensile polyester mesh backrest to support consistent airflow during extended use, paired with a 50D high-density molded polyurethane foam seat cushion with a 12mm plywood inner support core. Its frame combines fiberglass-reinforced PP for back and armrest structures, a 2.5mm stamped steel tilt chassis, 1.5mm steel tube internal reinforcement, and an injection-molded nylon five-star base, with an SGS-certified Class 4 steel gas lift and 60mm soft-tread dual-wheel PU casters. The seat cushion offers 60% rebound rate, and the mesh upholstery is rated to withstand 50000 abrasion cycles, while the five-star base carries a 1000kg static load rating. Designed for adaptable comfort, the chair supports pneumatic seat height adjustment via a side lever, a backrest that tilts from a 90° upright position to a 135° reclined angle with three lockable positions, and an under-seat knob to adjust tilt tension to match user weight. The headrest adjusts vertically and rotates to a 45° angle, the full assembly rotates 360 degrees for easy access to surrounding work surfaces, and a pull-out footrest extends from under the seat to support relaxed reclining positions. It supports a maximum recommended user weight of 181kg. This chair is suited for home office workspaces for long-duration seated tasks, corporate open office workstations for rotating daily use, executive private offices where its black finish complements formal decor, student study areas for teen to adult users, gaming and entertainment spaces for relaxed media use, and hot-desking shared workspaces where easy repositioning between users is required. For procurement, note each unit ships in two cartons, requires 40 minutes of assembly per set, and carries a net weight of 19kg with a packaged gross weight of 23kg per set.
