Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest and Fixed Armrests is an unbranded task chair designed for regular desk-based work. Model EM-HB-MESH-01, it presents a practical black office aesthetic, with a tall mesh back, integrated headrest, upholstered seat, fixed T-shaped armrests, and a five-star rolling base. Its high-back profile provides a structured silhouette for users seeking upper-back, head, and lumbar support in a straightforward commercial seating solution. Visual form and layout follow a conventional ergonomic office-chair arrangement. The backrest uses black flexible mesh stretched across a black molded outer frame, creating an open appearance while defining a dedicated lumbar support zone. A padded, upholstered headrest cushion is attached to the upper back frame. Below, the seat is a molded foam cushion covered in black woven fabric, while the armrests extend from the seat structure as black molded nylon T-arms with flat padded or capped pads. The black molded nylon five-star base supports the chair visually and functionally, with twin-wheel casters fitted at each of the five sockets. Construction combines several core materials. The seating surface uses molded polyurethane foam, the back and headrest feature black mesh, and the armrests and base are molded nylon. A chrome or steel pneumatic gas lift is paired with a black telescopic shroud, a steel tilt mechanism, and a right-side adjustment lever. The finished seat cushion thickness is 90 mm, the backrest padding thickness is 70 mm, the lumbar support zone height is 240 mm, and the clear width between the armrests is 540 mm. Overall dimensions are 660 by 650 by 1290 mm, and the headrest cushion measures 360 by 150 by 80 mm. Functionality is centered on adjustable task seating. The pneumatic seat-height control offers 90 mm of travel through the visible right-side lever. The reclining mechanism allows the back to reach a maximum angle of 118 degrees, with a tension knob located under the seat. The seat itself supports 5 degrees of forward tilt and 8 degrees of backward tilt, while the chair swivels 360 degrees around the central gas-lift axis. Five twin-wheel casters provide rolling mobility on hard floors and low-pile carpet. The chair is rated for a recommended user weight of 120 kg and has a net weight of 15 kg. This model is suitable for individual office desks, computer workstations, administrative seating, supervisor stations, meeting rooms, and home offices where high-back support and mobility are priorities. Its fixed armrests make it best suited to workstations where arm dimensions already suit the desk setup rather than environments requiring personalized arm adjustment. Procurement teams should plan for one set supplied in two cartons, with a packaged gross weight of 23 kg per set and reference assembly time of 40 minutes. The carton dimensions are 850 by 420 by 720 mm, and the reference carton volume is 0.26 cubic meters per set. Buyers should also confirm mesh grade, foam density, foam treatment, base glass-fiber content, and armrest load rating through the bill of materials or supplier documentation before final specification.
