The Grey High-Back Mesh Ergonomic Office Chair with Adjustable Headrest and Lumbar Support, model ERG-MSH-GRY-01, is an unbranded task seating solution built to deliver consistent, tailored comfort across a range of work environments. Visually, the chair features a streamlined, contemporary silhouette anchored by a polished silver 5-star base, neutral grey mesh and upholstery tones, and clean structural lines that complement modern interior design schemes without visual clutter. Its measured dimensions are calibrated to align with standard desk configurations, with a 700 mm tall backrest, proportioned 320 x 180 mm headrest, and evenly spaced caster layout to balance a stable footprint with unobtrusive placement around workstations. Construction prioritizes durability and long-term comfort across high-use settings. The backrest is wrapped in high-elastic breathable polyester mesh, while the seat combines 45 kg/m³ high-density polyurethane foam fill with wear-resistant breathable mesh upholstery. Armrests feature soft-touch polyurethane padding supported by reinforced glass-fiber nylon structures, set 110 mm above the seat surface. The 2.5 mm thick polished silver die-cast aluminum 5-star base supports a Class 3 50 mm diameter black steel gas lift, 3 mm thick stamped steel tilt chassis, and dual-wheel polyurethane casters with black nylon housings. The chair has a net weight of 19 kg, supports a maximum static load of 159 kg, and is rated for a recommended user weight of 136 kg. Functional design is centered on customizable ergonomic support. The headrest offers 2D height and angle adjustment with 50 mm of vertical travel, while the lumbar support provides 2D height and depth adjustment with 55 mm of vertical travel to align with individual spinal contours. Armrests adjust 40 mm vertically with a 15° pivot range, and seat height is modified via a side-lever operated pneumatic gas lift with 100 mm of stroke. The synchronized tilt mechanism enables 360° swivel, 126° of recline, tension adjustment via red control knobs, and three lockable recline positions at 90°, 110°, and 126°, while omnidirectional dual-wheel casters support smooth movement across floor surfaces. This chair is suited for private office workstations supporting 8+ hours of daily seated work, home office setups paired with 760 mm standard height work surfaces, open plan office shared task zones, conference rooms for 2 hour meeting sessions, high-turnover coworking spaces, and IT or design studio workstations where extended focused work is common. For procurement, note that each unit ships across 2 cartons with a total packaged gross weight of 23 kg and total carton volume of 0.26 m³, requires 40 minutes of assembly per set, and fits 135 units per 20GP container at 85% space utilization to support bulk order planning.
