The Black Faux Leather Dual-Back Ergonomic Office Chair with Headrest, model OFC-ERG-DBLB-001, is an unbranded commercial-grade seating solution designed for long-duration seated use. Visually, it features a streamlined neutral black finish, with a distinct split dual-panel backrest, contoured padded armrests, integrated height-adjustable headrest, and a five-star wheeled base that balances a professional aesthetic with functional structure, coordinating seamlessly with modern workspace design palettes. Its layout prioritizes natural posture alignment, with a dedicated 240mm tall lumbar support zone and 540mm clear width between armrests to accommodate comfortable movement during seated tasks. The chair is built for consistent heavy use: seat and backrest surfaces use 1.2mm thick black PVC faux leather, supported by 45kg/m³ density molded foam padding for the seat and main back, with 70mm thick backrest padding and 90mm thick finished seat cushion. The internal back frame uses 2mm thick powder-coated steel tubing, paired with a 3mm thick powder-coated nylon composite five-star base, 3mm thick stamped steel tilt control chassis, and 50mm diameter Class 3 steel gas lift. Armrests are supported by injection-molded glass-fiber reinforced nylon, topped with 40mm thick foam pads wrapped in matching faux leather, while dual-wheel polyurethane casters attach to the base for stable movement. Functionality is tailored for ergonomic comfort across diverse users: pneumatic seat height adjustment via a right-side lever delivers 100mm of vertical travel, and the synchronized seat-back tilt mechanism offers a 15-degree maximum recline with multi-position lock, plus an under-seat knob to adjust tilt tension to match user weight. The independent split back panels provide 50mm of depth adjustment for targeted lumbar support, while the headrest adjusts 80mm vertically and tilts 30 degrees to support the neck. Full 360-degree swivel and smooth-rolling casters that perform on both carpet and hard flooring support easy movement, with a rated maximum static user load of 150kg, 8 hours of recommended daily use, and durability ratings covering 100,000 gas lift cycles, 100,000 caster rolling cycles, and 50,000 Martindale abrasion cycles for upholstery. This chair is suitable for private office workstations for executive and staff desks, open plan commercial offices, home office setups for remote workers, conference meeting rooms, co-working shared spaces, and pairing with height-adjustable sit-stand desks.
