Product Description

The Black Mesh Ergonomic Task Chair with Fixed Armrests and Lumbar Support is an unbranded office seating solution, model ETC-MESH-FA-LB-01, designed for daily workstation use. Its black woven polymer back is tensioned within a molded polymer frame, creating a breathable visual surface paired with a black fabric-upholstered seat. Fixed black injection-molded polymer T-arms, a five-star base, and twin-wheel casters give the chair a practical commercial appearance. Overall dimensions are 630 by 620 by 1040 mm. The seat cushion has a finished thickness of 90 mm and uses molded polyurethane foam with a density of 45 kg/m3 and an indentation load deflection of 55 N, covered in black woven fabric. The backrest padding thickness is 70 mm, while the lumbar support zone is 240 mm high. The clear width between armrests is 540 mm. Internal support is provided by a 12 mm molded plywood or reinforced polymer seat carrier. Fixed armrests use steel mounting brackets, and the base is constructed from glass-fiber-reinforced nylon. Mobility is supported by 50 mm black twin-wheel casters, while height and tilt functions use a 50 mm steel gas lift and a black powder-coated tilt mechanism with lever. The chair weighs 13.5 kg and has a recommended user weight capacity of 120 kg. Functional features support regular task-chair movement. The right-side lever controls pneumatic seat-height adjustment through a 100 mm stroke, and the seat rotates 360 degrees on the central gas lift and caster base. A synchro tilt mechanism lets the seat and back move together, with a 15-degree maximum recline. The curved rear lumbar pad contacts the lower mesh back and includes a visible central adjustment dial, allowing users to tailor lower-back support. Verification and durability targets include a 660 kg static seat load, 120,000 backrest cycles, and 100,000 caster rolling cycles. The chair is suited to open-plan workstations and individual desk work, where the mesh back, swivel base, and height lift accommodate repeated posture changes. Its rolling five-star base and compact footprint also make it appropriate for hot desks, training offices, meeting rooms, computer rooms, and shared computer stations. For procurement, each set is supplied in two cartons, with reference packaged gross weight of 23 kg and reference carton volume of 0.26 m3 per set. Planning should allow 40 minutes for assembly per set. Buyers should review supplied dimensional, material, and logistics details against intended flooring, desk height, shared-use frequency, and receiving or installation requirements.
