Product Description

The High-Back Black Mesh Ergonomic Office Chair with Headrest and Polished Aluminum Base presents a professional task-seating solution with a structured, breathable appearance. Its tall black mesh back is set within a black molded outer frame, while the curved mesh headrest carries a matching black shell and rear adjustment bracket. The upholstered black fabric seat has a rounded front edge, and the black molded arm pads sit on height-adjustable posts with silver trim collars. Below, the polished die-cast aluminum five-star base gives the chair a refined visual contrast against the black frame and supports a chrome-finished steel gas-lift column. Overall dimensions are 680 by 680 by 1280 millimeters, with 540 millimeters of clear width between the armrests. The 90 millimeter finished cushion incorporates an 80 millimeter foam pad, the backrest padding thickness is 70 millimeters, and the lumbar support zone is 240 millimeters high. Construction combines flexible woven mesh, upholstered foam, molded arm pads, a black steel multi-function tilt mechanism, and nylon twin-wheel casters. The mechanism is controlled by underside levers and a tension cable. A 50 millimeter diameter Class 4 gas lift provides 80 millimeters of seat-height travel through a right-side paddle, and the chair supports a recommended user weight of 150 kilograms. Its listed verification targets include a 680 kilogram static seat load, 136 kilograms of backrest pull-back force, and 100000 caster rolling cycles. Functionally, the seat and back move together through a 15 degree synchronous recline path with adjustable spring tension, and the multi-position tilt lock secures angles from upright through full recline. The padded arms adjust 60 millimeters in height and pivot 15 degrees inward or outward, allowing the chair to suit different desk and posture preferences. These features make it appropriate for open-plan offices, executive workstations, and home offices requiring 10 hour task support. It can be specified individually as an executive chair or purchased in multiple units for management and focus-task seating. Procurement teams should note that this unbranded model, EM-HB-MESH-ALU-01, is supplied as one set across two cartons, with a packaged gross weight of 23 kilograms, reference carton volume of 0.26 cubic meters, and a reference assembly time of 40 minutes per set.
