Product Description

The High-Back Mesh Ergonomic Office Chair with Adjustable Headrest, model ERC-MESH-HB-01, is an unbranded task seating solution designed for prolonged desk work. Its overall dimensions are 680 x 680 x 1290 mm, presenting a tall, upright profile with a black mesh backrest and dark gray woven fabric seat. The color palette of black and dark gray gives it a restrained, professional appearance that integrates readily with neutral office interiors. The chair follows a conventional executive-task layout, with a five-star caster base, central gas lift, contoured seat, height-adjustable armrests, high backrest, and adjustable headrest. The clear width between armrests is 540 mm. Visual contrast comes from the breathable black-gray elastic mesh, which is stretched within a molded polymer frame, while the dark gray seat upholstery provides a softer visual anchor. The back frame is produced from injection-molded black nylon or polypropylene, and the assembly uses a nylon frame and base with a steel gas lift and polyurethane casters. Seating comfort is built around layered support. The finished seat cushion is 90 mm thick and includes a 50 mm molded polyurethane foam core with a foam density of 45 kg/m3. The backrest padding thickness is 70 mm, and the lumbar support zone height is 240 mm. A contoured polymer lumbar pad is connected through a steel support link and controlled by a circular tension knob, allowing users to adjust support tension or depth for the lower back. The armrests use black height-adjustable polymer posts with padded polymer top pads. Functional controls support flexible working postures. A pneumatic right-side lever adjusts seat height through a 90 mm stroke, from 450 to 540 mm. The synchro-tilt mechanism allows the backrest to recline 30 degrees, from 95 to 125 degrees, while the seat moves in coordinated proportion. A rear circular knob adjusts recline resistance, and the mechanism offers lockable upright and reclined positions. Swivel movement and rolling polyurethane casters support mobility around bench desks, executive desks, and fixed workstations. The chair is suited to commercial project installation in open offices, call centers, and management rooms, as well as home offices requiring task seating with recline and caster mobility. It is appropriate for 10 hour desk work due to its high back, lumbar support, and adjustable arms. The recommended user weight capacity is 150 kg, net weight is 18.5 kg, and the packaged gross weight is 23 kg per set. Procurement teams should plan for two cartons per set, a reference assembly time of 40 minutes, and reference carton dimensions of 850 x 420 x 720 mm. The reference carton volume is 0.26 m3 per set, with indicative loading of 135 sets in a 20GP container at 85 percent space utilization.
