The Grey High-back Ergonomic Mesh Office Chair with Retractable Footrest, model ERG-MSH-GRY-FR-01 from Bolongkeli Smart Furniture, presents a streamlined, professional silhouette defined by its tall, contoured high-back structure, polished silver five-star caster base, and coordinated neutral grey upholstery that blends seamlessly with a range of interior design palettes. The layout prioritizes user-centered adjustability, with aligned support points for the head, upper back, lumbar region, arms, and legs to create a cohesive seated experience. Built for durable long-term use, the chair features a backrest upholstered in grey breathable polyester mesh, paired with a seat of matching grey breathable mesh over high-density molded foam for balanced comfort and airflow. Its back frame is constructed from PA66 nylon reinforced with 30 percent fiberglass, while armrests combine soft molded PU pads on rigid supports with silver-painted aluminum alloy structures. The polished silver aluminum alloy five-star base supports PU tread casters with nylon hubs and black accent rings, paired with a chrome-plated Class 3 steel gas lift and 3mm thick stamped steel tilt mechanism chassis for sturdy, reliable operation. Comprehensive ergonomic functions include full 360-degree swivel rotation, pneumatic seat height adjustment controlled via a side lever, 4-position backrest recline locking up to 135 degrees from upright with adjustable tilt tension, and a retractable under-seat footrest that slides and folds out from the front seat base for leg support during relaxed postures. Users can also adjust the headrest for height and 45-degree angle tilt, fine-tune the 2D lumbar support for height and depth to match natural lower back curvature, and modify armrest height across 100mm of vertical travel to suit individual positioning needs. This chair fits a wide array of commercial and residential spaces. It delivers multi-position ergonomic support for extended daily desk work in executive office workspaces, and its compact footprint and modern grey finish complement residential home office studies. In open plan workstations, its smooth-rolling casters and swivel function support active collaborative work, while its broad adjustability accommodates users of varying heights in meeting and conference rooms. The recline and footrest features suit extended gaming and hobby sessions, and quick, intuitive adjustments make it ideal for flexible hot-desking environments serving rotating users. For procurement planning, note each unit ships in two cartons, with a reference assembly time of 40 minutes per set. Logistics data supports efficient bulk shipping for large project orders, and the chair supports a recommended static load capacity suited for diverse user groups. The neutral colorway and durable material finishes allow consistent furnishing across mixed-use work zones without style mismatch.
