The Grey Mesh High-Back Ergonomic Office Chair with Headrest and Retractable Footrest (model ERG-OFC-MSH-FT-001) is an unbranded public and workplace seating solution defined by clean, modern lines and a coordinated neutral grey finish that blends seamlessly across professional environments. Its contoured high-back silhouette integrates a height-adjustable mesh headrest, fixed curved armrests, and a pull-out footrest stored flush beneath the seat to maintain a streamlined, uncluttered profile when not in use. The five-star chrome base and black twin-wheel casters create a balanced, polished visual foundation suited to both formal and casual work settings. Constructed for long-term repeated use, the chair features a glass-fiber reinforced polypropylene structural frame supporting a backrest upholstered in breathable elastic polyester mesh, paired with a 40mm thick high-density foam seat cushion wrapped in matching mesh. The 1.5mm thick chrome-plated steel five-star base supports an SGS Class 3 chrome-plated steel gas lift cylinder, connected to a 2.5mm thick steel plate recline mechanism with multi-position lock. The chair uses 60mm black PU twin-wheel casters, fixed light grey PP arm pads with integrated support posts, and an elastic mesh headrest mounted on a PP support frame. All material and structural components are engineered to withstand regular multi-user operation. Functional features are designed to support varied working postures across extended use. Pneumatic seat height adjustment operates via a side lever with 135mm of travel, while the lockable backrest reclines up to 135 degrees with adjustable tension, paired with a contoured fixed lumbar zone aligned to natural lower back curvature. The height-adjustable headrest supports the neck in both upright and reclined positions, and the under-seat retractable footrest extends 280mm to support short rest breaks. Full 360-degree swivel around the central axis enables multi-directional access, and the twin-wheel casters deliver smooth rolling mobility on hard floors and low-pile carpet. This chair is suitable for corporate open office workstations for 8-hour daily seated work, home office study spaces paired with standard 760mm height desks, executive private offices for extended work and short rest breaks, co-working shared workspaces for rotating multi-user use, and meeting and conference rooms where mobility supports easy table-side collaboration. It pairs ideally with 2.4m executive desks. Procurement teams should note the chair ships as one set across two cartons, with a packaged gross weight of 23kg per set and total carton volume of 0.26 cubic meters per set. On-site assembly requires 40 minutes per unit. At 85% space utilization, a 20GP shipping container holds 135 sets, with a maximum recommended user weight of 204kg to support long-term durability in high-traffic public and workplace settings.
