The Black High-Back Mesh Ergonomic Office Chair with Retractable Footrest from Bolongkeli Smart Furniture, model ERG-MESH-FR-01, delivers tailored support for extended seated use across professional and residential settings. Its streamlined high-back silhouette features a structured five-star base, with a cohesive black finish that complements a wide range of interior design schemes. The layout prioritizes intuitive adjustability, with all control points positioned within easy reach for seamless transitions between focused work and rest positions. Built for consistent long-term use, the chair pairs a tight-woven breathable polyester mesh backrest with a seat constructed from high-density molded polyurethane foam topped with breathable mesh upholstery, balancing airflow and cushioned support. Its structural frame is crafted from nylon reinforced with 30% glass fiber, while soft polyurethane-padded armrests mount to height-adjustable injection-molded nylon support posts. The five-star base is formed from powder-coated steel, supporting a Class 3 certified steel gas lift, and the retractable footrest uses steel tube construction with a smooth PP foot pad. The chair supports 360-degree swivel and smooth rolling movement across floor surfaces, with pneumatic seat height adjustment, a 140-degree maximum backrest recline with four locking positions, and fully customizable support components: 4D adjustable armrests, a multi-adjustable headrest, and height- and depth-tunable lumbar support. The pull-out footrest locks securely when extended to support relaxed reclining during short workday breaks. This model is well suited for corporate open office workstations, supporting 8 hours of daily desk work with targeted ergonomic alignment. It also fits standard-height home office desks with its space-efficient footprint, complements executive furnishing sets in private manager offices, and adapts to diverse user needs in co-working spaces. It accommodates adult users up to 183cm tall for proper ergonomic fit. Procurement teams should note the chair ships in two cartons per set, with a straightforward assembly process, and supports high-volume container loading for large-scale furnishing projects. When planning layouts, account for the chair’s full assembled footprint to ensure adequate clearance for recline and swivel movement around work surfaces.
