The Grey High-Back Mesh Ergonomic Office Chair with Retractable Footrest and Adjustable Headrest (model ERG-MESH-GREY-FR-01, unbranded) features a streamlined, contemporary form defined by a tall contoured backrest, proportioned five-star base, and coordinated neutral grey finishes that blend seamlessly with a range of interior design schemes. The overall structure measures 740 by 760 by 1310 mm, with a 700 mm diameter polished die-cast aluminum alloy five-star base fitted with 60 mm soft PU casters for smooth, floor-friendly movement. The chair’s construction prioritizes durable, long-wearing components: the backrest uses breathable grey woven polyester mesh, while the seat pairs matching breathable grey mesh over 80 mm thick, 50 kg/m³ high-density molded foam for balanced support and ventilation. Its structural frame is made of reinforced light grey glass-fiber nylon, paired with a chrome-plated Class 3 steel gas lift column rated for 120,000 durability cycles, a 3 mm thick powder-coated stamped steel tilt mechanism plate, and soft polyurethane-padded armrests mounted on height-adjustable nylon stems. The retractable footrest uses a mesh-padded steel and nylon sliding assembly, and the mesh upholstery carries a 50,000 Martindale cycle abrasion resistance rating to withstand regular daily use. The chair supports a maximum recommended user weight of 150 kg, and delivers a full suite of ergonomic functions for all-day comfort: full 360-degree swivel rotation, lever-operated pneumatic seat height adjustment with 90 mm of vertical travel to reach a maximum seat height of 570 mm, multi-position backrest tilt and lock between 90 degrees upright and 135 degrees recline, height-adjustable contoured lumbar support that aligns with the natural lower back curve, a 340 by 190 mm headrest with 60 mm height travel and 35-degree angle adjustment, 3D armrests with 70 mm height adjustment plus forward/back and pivot movement, and a slide-out footrest that locks securely in both extended and retracted positions. This model is suited for a wide range of spaces, including home office workstations supporting remote work, open-plan commercial offices with shared work areas, executive private offices for focused work and short rest breaks, computer and gaming setups for extended screen time, study rooms serving teens and adults at standard writing desks, and meeting and conference rooms supporting collaborative activity. Procurement teams should note that each chair ships as one set across two cartons, with a packaged gross weight of 23 kg per set, total carton volume of 0.26 cubic meters per set, and a reference assembly time of 40 minutes per unit. When planning bulk shipping, 135 sets can be loaded into a 20GP container at 85% space utilization, making the model practical for both individual purchase and large-scale commercial outfitting projects.
