Product Description

The Black Mesh High-Back Ergonomic Task Chair with Headrest, model MB-HB-HR-5P-01, is an unbranded seating solution built for focused desk work and extended computer use. Its tall black frame combines a breathable woven mesh back with a contoured headrest, fixed T-shaped armrests, and a five-star caster base, giving the chair a streamlined professional appearance suited to modern office interiors. The back mesh is tensioned within a black molded polymer or resin frame and organized into three horizontal support zones, including a 240 mm lumbar support area. The curved headrest uses a mesh or fabric-faced pad on a molded black shell, attached with a steel or polymer bracket. Clear width between the fixed armrests is 540 mm, while integrated flat elbow pads provide a consistent forearm surface. Construction balances comfort and structure. The seat features black woven fabric over 70 mm molded foam at 45 kg per cubic meter, with a finished cushion thickness of 90 mm and a concealed plywood or molded-composite shell. Backrest padding thickness is 70 mm. Armrests and the headrest shell are molded polymer, while the gas-lift and tilt mechanism use steel. The chrome-finish steel lift column includes a black telescopic trim sleeve, and the chair rests on a nylon five-star base with twin-wheel casters. Functional controls are arranged for regular task-chair use. A pneumatic lever adjusts seat height through a 100 mm stroke, from 440 mm to 540 mm. The synchronized recline allows the backrest to tilt up to 18 degrees with coordinated seat movement and a position lock. A rear rotary knob controls recline resistance, and the seat and back rotate through 360 degrees. The independent headrest adjusts 90 mm vertically and pivots for neck support during reclined work or breaks. Rated capacity is 136 kg, with suitability for users up to 188 cm in height. The caster rolling durability target is 100000 cycles. This chair fits individual open-plan workstations, private offices, home offices, conference rooms, study rooms, and shared computer desks used in eight-hour shifts. Buyers should plan for assembly, noted at 40 minutes per set. Each set ships in two cartons with a packaged gross weight of 23 kg and reference carton volume of 0.26 cubic meters; listed carton dimensions include 840 x 650 x 360 mm and 850 x 420 x 720 mm.
