Product Description

The High-Back Adjustable Mesh Ergonomic Office Chair (Model ERG-MESH-6668-HB, unbranded) delivers structured, supportive seating built for extended daily use. Its streamlined, professional silhouette features a tall contoured mesh back anchored to a reinforced black nylon five-star base, with soft-touch padded armrests and an integrated adjustable headrest that balances visual lightness with robust structural presence. The overall form measures 660 x 680 x 1290 mm, with a 500 mm wide, 460 mm deep seat and a 580 mm tall backrest measured from the seat surface, creating a proportional layout that fits neatly alongside standard work surfaces without overwhelming surrounding space. Construction prioritizes durability and long-haul comfort: the backrest uses breathable polyester office mesh rated for 50000 Martindale abrasion cycles, stretched over a glass-fiber reinforced nylon frame with a built-in S-curve lumbar support zone. The seat pairs a 45 kg/m³ high-density cold-cured molded foam core with wear-resistant polyester fabric upholstery, mounted to a 2.5 mm thick stamped steel tilt mechanism plate. Height adjustment relies on a chrome-plated Class 3 steel gas lift rated for 120000 lift cycles, connected to dual-wheel non-marking polyurethane casters tested for 40000 rolling cycles. Functional design supports flexible working postures: a 100 mm stroke seat height adjustment operates via an under-seat lever, while the backrest offers 135-degree recline with adjustable tension and 3 lockable positions. The seat swivels 360 degrees on the central bearing, the headrest adjusts 60 mm in height with variable tilt, and armrests move 100 mm vertically with 4-direction position locking. The casters roll smoothly across hard flooring and low-pile carpet without leaving surface marks. This chair is suited for 8-hour daily use in open-plan office workstations, private offices, home study remote work setups, and collaborative conference rooms, accommodating users up to 185 cm tall and pairing seamlessly with standard 760 mm height office desks. For procurement, note each unit ships in 2 cartons with a packaged gross weight of 23 kg and total carton volume of 0.26 m³, requires 40 minutes of assembly per set, and supports a maximum static user load of 150 kg, making it a reliable choice for high-traffic work environments.
