Product Description

The Black Mesh Ergonomic Office Chair with Height-Adjustable Headrest and Fixed Arms presents a streamlined, high-back task-seating form in a restrained black and dark gray palette. Its mesh back is tensioned within a black polymer outer frame and follows a central back spine, while a fixed black polymer lumbar panel supports the lower-back region. The padded headrest combines a black outer cushion with a gray mesh insert and polymer support housing. Fixed black polymer T-arms with molded elbow pads and vertical posts frame the seat, giving the chair a structured workstation profile suited to neutral office interiors. Construction balances breathable support with practical durability. The backrest uses dark gray elastic mesh, and the seat features a molded foam pad upholstered in black woven or polyurethane material. Supporting components include a black plastic frame, fixed plastic armrests, a chrome-free black steel gas lift, a steel tilt mechanism under a polymer seat shell, and a nylon five-star base with twin-wheel casters. The chair has a finished seat cushion thickness of 90 mm, backrest padding thickness of 70 mm, lumbar support zone height of 240 mm, and 540 mm of clear width between the armrests. Overall dimensions are 660 x 660 x 1290 mm. Functional adjustment is focused on everyday desk use. A visible under-seat lever controls pneumatic seat-height adjustment with a 100 mm stroke. The synchronized seat-and-back tilt offers 24 degrees of rearward travel and includes tension control, while the center column allows 360-degree swivel movement. The headrest adjusts 80 mm in height along its central support post. Twin-wheel casters support movement across typical workplace seating layouts, and the fixed arms help maintain a consistent visual and spatial footprint. The recommended user weight capacity is 136 kg, and the chair has a net weight of 16.5 kg. This model is appropriate for individual workstations, computer desks, and shared administrative seating in open offices. Its black appearance also makes it suitable for meeting rooms and home offices where a coordinated, mobile task chair is required. For procurement planning, note that one set is supplied in two cartons, with a packaged gross weight of 23 kg and reference carton volume of 0.26 cubic meters per set. The reference assembly time is 40 minutes per set, so receiving, installation, and replacement scheduling should allow for on-site fitting. Buyers should also confirm floor surface compatibility, desk height, and arm clearance, particularly where the chair will be used with fixed-height workstations or enclosed work areas.
