The Ergonomic High-Back Mesh Office Chair with Retractable Footrest and Adjustable Headrest from Bolongkeli Smart Furniture (model ERG-OFC-MESH-001) balances structured ergonomic support with streamlined professional styling. Its form centers on a tall, contoured high-back silhouette paired with a polished die-cast aluminum five-star caster base, creating a stable, polished footprint that fits seamlessly across professional and casual work environments. The clear width between armrests creates ample personal space, while integrated adjustable components sit flush with the frame to maintain a clean, uncluttered visual profile even when components are adjusted for individual comfort. Durable, performance-focused materials form the core of the chair’s construction. The backrest and adjustable headrest are upholstered in tensioned breathable black polyester mesh, paired with a 70mm padded backrest section and 240mm tall dedicated lumbar support zone. The 90mm thick seat cushion uses a high-density molded polyurethane foam core rated at 45 kg/m³ density, while armrests feature soft-touch polyurethane padding mounted on reinforced black polypropylene structural frames, matching the back frame construction. Support components include a chrome-plated steel Class 3 gas lift, 3mm thick cold-rolled steel tilt and lock chassis, dual-wheel polyurethane casters with metal roller bearings, and a retractable footrest finished with breathable black mesh over a polypropylene support frame. The chair holds a maximum static load capacity of 150 kg, with a 90 kg maximum static load rating for backrest recline, 100,000-cycle caster rolling durability, and 120,000-cycle gas lift rating, supporting 8 hours of recommended daily use at a net weight of 23 kg. Customizable comfort features accommodate a wide range of user preferences. Seat height adjusts via a right-side lever with 100mm of vertical travel through the Class 3 gas lift, while the backrest reclines to 135 degrees with multi-position tension adjustment and lock. The headrest offers 50mm of height adjustment and 25 degrees of tilt rotation, armrests adjust 70mm vertically to align with desk and elbow heights, and the pull-out footrest extends 280mm from under the seat to support legs during reclined rest. Full 360-degree swivel rotation and smooth-rolling dual-wheel casters enable easy movement across carpet, tile, and hardwood flooring to access surrounding workspace areas without strain. This chair is suited for a broad range of settings, including commercial open-plan and private office workstations, home office spaces for remote workers, conference and meeting rooms for extended collaborative sessions, executive offices where its high-back design delivers both comfort and a professional aesthetic, recreational gaming spaces where its recline and footrest support casual use, and shared co-working spaces where durable construction and flexible adjustments serve diverse rotating user groups.
