Product Description

The Black Split Dual-Back Ergonomic Office Task Chair, model TASK-DB-700BLK from Bolongkeli Smart Furniture, is a purpose-built seating solution balancing professional aesthetics, functional support, and durable construction for everyday use. Its visual design features a streamlined, all-black profile anchored by a five-star base, with a split dual-back structure formed by two contoured mesh-backed pads that create a distinct, ergonomic silhouette. The fixed, padded armrests sit at a consistent height relative to the seat, aligning neatly with the seat and backrest for a cohesive, understated look that complements standard office decor without visual clutter. Built for long-term use, the chair combines robust, application-specific materials across every component. The seat is upholstered in thick black woven polyester fabric, padded with high-density polyurethane foam for consistent support, while the dual backrest pads are covered in breathable black polyester mesh stretched over an injection-molded polypropylene frame. Armrests feature rigid polypropylene supports topped with soft polyurethane padding, the five-star base is constructed from glass-fiber reinforced nylon for structural stability, and a chrome-plated steel Class 4 gas lift forms the central support column. Dual-wheel nylon casters with PU treads are designed to work smoothly across both hard and soft floor surfaces, and the stamped steel butterfly tilt plate delivers reliable recline function through regular use. Core functional features support comfortable, flexible seated work across long sessions: pneumatic seat height adjustment is controlled via a side lever, the chair swivels a full 360 degrees for easy multi-directional access to work surfaces, and the backrest offers a 30-degree backward recline with adjustable tension and an upright lock, plus three additional suggested lock positions for customized support. The fixed split back pads distribute upper back pressure in a set ergonomic alignment, while the stationary padded armrests provide stable forearm support ideal for typing tasks. This chair is suited for a wide range of commercial and residential spaces, including open plan office workstations for daily 8-hour staff use, compact home office setups for remote work, high-traffic co-working shared spaces that see frequent multi-user turnover, professional conference and meeting rooms, and call center or helpdesk stations where consistent posture support is needed across long shifts. It pairs well with standard desk configurations, including larger executive desk setups. For procurement teams and individual buyers, key considerations include its two-carton packaging, 40-minute per-unit assembly time, and packaged weight, which support straightforward receiving and setup workflows. Its commercial-grade material durability ratings make it a strong choice for high-use environments, while the uniform black finish allows for easy coordination with existing furniture inventories across different space types.
