This high-back padded swivel ergonomic office chair (model EOCHB-FA119) delivers professional, supportive seating for a wide range of work environments, with a streamlined, contoured design finished in sleek black upholstery. The chair features a tall, curved high backrest paired with fixed curved armrests, set atop a polished chrome-plated five-star base fitted with smooth-rolling casters, creating a clean, professional silhouette that balances structured support and understated visual appeal. Construction prioritizes durability and long-wearing comfort across daily use. Seat and back surfaces are upholstered in 1.0mm thick black PU faux leather, stitched with consistent 8mm seam detailing for a tailored finish. Seat cushions use a high-density polyurethane foam core wrapped in a fabric liner, paired with a curved polypropylene back support frame bonded to molded foam padding; fixed polypropylene armrests include soft padded top surfaces for rested forearm support. The base is formed from thick polished chrome-plated steel, connected to a Class 3 chrome-plated steel pneumatic gas lift, steel tilt chassis, and dual-wheel non-marking black nylon casters. Core functional features support comfortable, flexible working postures. A right-side under-seat lever controls pneumatic seat height adjustment, while an under-seat knob lets users tune tilt tension to match individual preference, and the backrest reclines to a 135-degree angle with a lockable upright position. The central swivel joint enables full 360-degree rotation, and the five casters roll smoothly across both hard and soft floor surfaces without leaving scuffs. The contoured mid-back section provides targeted lumbar support aligned to the spine’s natural curve, and fixed armrests offer consistent elevated support above the seat. This chair is well suited for private office workstations, open-plan commercial office zones, home office studies, conference rooms, shared co-working spaces, and setups paired with height-adjustable sit-stand desks. When planning procurement, note that each unit ships in two cartons, with a listed assembly time per set and a packaged gross weight for shipping calculations. The design supports a recommended maximum user weight, and its durable, stain-resistant upholstery and non-marking casters hold up to regular high-turnover use, while its compact footprint fits neatly in smaller work areas without occupying excess floor space.
