Product Overview & Construction Details

This high-back ergonomic mesh office chair is engineered for extended seated work in professional office and home workspace environments. Its tall backrest combines a breathable dark-gray elastic mesh surface with a robust black reinforced nylon frame, delivering both ventilation and structural support. An integrated sliding lumbar bar allows vertical repositioning to align with individual lower-back curves, while an adjustable mesh headrest on a central bracket adds neck support for upright and reclined postures. The seat features a molded foam cushion upholstered in olive-green woven fabric, paired with fixed black nylon armrests for stable arm support during typing or reading. Operationally, the chair includes pneumatic seat height adjustment via a side lever, a multi-position backrest recline lock with tilt tension control, and a full 360-degree swivel function. It sits on a black nylon five-star base fitted with 50 mm twin-wheel nylon casters for smooth mobility across typical office flooring. The overall configuration delivers a professional, clean aesthetic suited to open-plan workstations, private executive offices, conference rooms, call centers and home desks. For procurement evaluation, key engineering considerations include seat height range, lumbar adjustability, backrest tilt positions, base diameter, caster size, expected load capacity and typical knock-down packaging parameters. Buyers should confirm material grades, foam density, gas lift class, durability test reports and exact carton specifications with the supplier before final purchase or bulk ordering.
