Product Description

The Black Mesh High-Back Ergonomic Task Chair with Headrest and Fixed Arms presents a clean, professional profile suited to sustained desk work. Its tall black mesh back curves upward to support the full back, while the integrated headrest extends the vertical line and adds a dedicated contact point behind the head. The black molded T-arms frame the seat with horizontal pads and vertical supports, and the five-star base with twin-wheel casters creates a stable, mobile foundation suited to swivel-based workstations. Construction combines breathable and structured components. The back and headrest use black woven polymer mesh suspended over a curved polymer outer frame, while the load-bearing back structure uses an injection-molded polypropylene shell reinforced at the lower section by a rigid Y-shaped brace. The seat features a molded polyurethane foam cushion with a black woven fabric or mesh textile cover. Fixed armrests and the frame are molded in black plastic, the central column is a black-painted steel gas lift, and the base is formed in black nylon. Product dimensions are 650 x 650 x 1320 mm, with a 90 mm finished seat cushion, 70 mm backrest padding, a 240 mm lumbar support zone, and 540 mm of clear width between the armrests. Functional adjustment is concentrated around individualized seating posture. A right-side lever controls the pneumatic seat-height lift through its 100 mm stroke. The synchro tilt mechanism permits 18 degrees of rearward back movement with proportional seat movement and lockable positions. A rear knob-and-bracket assembly adjusts lumbar support height through 70 mm of vertical travel, and the curved mesh headrest offers 80 mm of height adjustment plus 30 degrees of pivot. The recommended user weight capacity is 150 kg and recommended user height is 185 cm; the chair itself weighs 16.5 kg. This model fits open-plan workstations, private offices, and home offices where full-back support, swivel movement, and mobility across carpet or hard floors are required. For coordinated workspace planning, it pairs effectively with 720 mm deep desks and monitor arms, and it is suitable for fleet deployment in 20-unit batches or larger. Buyers should account for delivery as one set packed in two cartons, a packaged gross weight of 23 kg per set, 0.26 cubic meters of carton volume, and a reference assembly time of 40 minutes per set. The unbranded EMH-MESH-HB-01 is best specified where a uniform black task chair, fixed arms, adjustable lumbar support, and a high-back mesh structure are priorities.
