Product Description

The YUXIANG EMOC-635-BLK High-Back Ergonomic Mesh Office Chair delivers a balanced blend of structured support and streamlined, professional aesthetic suited to extended seated use. Its visual profile features a tall, contoured high-back form finished in uniform black, with a structured upright layout that pairs a breathable mesh backrest, integrated curved lumbar zone, adjustable padded armrests, and height-adjustable headrest, all mounted to a wide five-star base with smooth rolling casters. The chair’s construction prioritizes long-term durability and consistent comfort: the backrest is upholstered in high-tensile breathable polyester mesh, while the seat uses a high-resilience cold-cure polyurethane foam core surfaced with breathable woven mesh fabric. The internal structure relies on a reinforced 3mm thick steel inner frame, paired with a glass-filled nylon five-star base, 2.5mm thick stamped steel tilt chassis, SGS Class 4 steel pneumatic gas lift, reinforced PA plastic padded armrests, and 60mm dual-wheel PU silent casters. Functional design is tailored to flexible working needs: pneumatic seat height adjustment covers 85mm of travel to align with varied desk heights, the headrest offers 60mm of vertical lift to support neck posture for taller users, and armrests adjust 70mm vertically to match desk surface heights. The backrest reclines to 135 degrees with adjustable tension control for relaxed postures, 360-degree swivel enables easy multi-directional access to desk surfaces, and the dual-wheel casters roll smoothly across all floor types. The integrated contoured lumbar zone aligns with the natural curve of the lower back to reduce strain during long work sessions. This chair fits a wide range of commercial and residential spaces, including private office workstations for administrative staff completing 8 hours of daily seated work, home office setups for remote workers seeking consistent neck and lumbar support, open-plan and co-working shared task stations, and conference room seating for flexible meeting postures. It also pairs seamlessly with height-adjustable sit-stand desks, and is recommended for use with a 2.4m executive desk. For procurement planning, note that each unit ships in two cartons, with a reference assembly time of 40 minutes per set, and a static base load rating that supports a recommended user weight capacity of 181kg. The mesh upholstery carries a 50000 Martindale double rub abrasion rating, seat foam has a density of 55kg/m³, and the gas lift is rated for 120000 cycles of use, supporting long-term deployment in high-traffic shared environments. At 85% space utilization, 135 sets fit in a 20GP shipping container for bulk order planning.
