The ERG-MESH-680-FR ergonomic office chair is an unbranded public and workspace seating solution designed to balance long-session comfort, functional flexibility, and durable construction. It features a contoured high-back silhouette with a wide, curved mesh headrest, fixed matte curved loop armrests, a generously sized padded seat, and a polished chrome five-star caster base. The retractable footrest tucks flush beneath the seat when not in use, maintaining a streamlined profile that does not impede movement around work surfaces. All adjustment controls are positioned within easy reach under the seat, creating an uncluttered, intuitive layout for all users. The chair is built for extended daily use, with a tensioned breathable nylon mesh backrest stretched over a plastic support frame to promote consistent airflow. The seat pairs a matching breathable mesh surface with 55D high-density foam padding, supported by an internal frame of 12mm thick plywood and a 2.5mm steel chassis plate. Fixed armrests are constructed from hard matte PP plastic, while the 2mm wall thickness chrome-plated steel five-star base supports a Class 3 steel gas lift with 50mm tube diameter. Smooth 50mm PU silent swivel casters allow 360-degree rotation for full mobility, and the retractable footrest uses a steel support frame with PP padded surface on an under-seat sliding track. It carries a 3-year warranty, with performance ratings including 200kg maximum recommended user weight, 1100kg five-star base static load, 100,000 caster rolling cycles, and 50,000 Martindale cycles of mesh abrasion resistance. Core functional features include 100mm lockable seat height adjustment across a 730mm range, 150-degree maximum backrest recline with three lock positions covering upright work and rest modes, adjustable tilt tension to match user weight, 60mm vertical lift and 35-degree rotation for the headrest to support neck posture, and a footrest that extends 300mm to support legs during recline. The casters roll smoothly on hard floors and low-pile carpet without scratching surfaces, and full 360-degree swivel enables easy multi-directional access to surrounding work areas. This chair is suitable for home office workspaces for long computer work sessions, open plan office workstations paired with standard 760mm height commercial desks, workplace nap and rest break areas for short mid-shift rests, and conference rooms to support flexible movement during collaborative discussions. It accommodates users up to 185cm tall via its adjustable seat and headrest. For procurement, note that each unit ships in 2 cartons, requires 40 minutes of assembly per set, and 135 sets can be loaded in a 20GP container at 85% space utilization.
