The Two-Tone Mid-Back Upholstered Swivel Office Chair from YUXIANG, model MB-OFC-2T-CH70, presents a polished, contemporary silhouette defined by its distinct two-tone upholstery and sleek chrome accents. The chair features a structured mid-back profile paired with integrated fixed armrests, anchored by a wide, polished five-star caster base that creates a balanced, professional visual presence suited to both formal and casual work environments. Its construction prioritizes long-wearing durability and consistent support. Front-facing contact surfaces including the seat, inner backrest, and armrest tops use thick two-tone camel brown artificial leather engineered for repeated use, while outer back and arm surfaces are finished in color-matched dark taupe artificial leather that coordinates with frame details. The internal support structure is built from welded, powder-coated steel tube, with a thick polished chrome-plated steel five-star base, SGS-certified Class 3 gas lift, and powder-coated steel synchro-tilt chassis. Seat and backrest cushions use high-density polyurethane foam with tuned rebound properties, and armrests feature a molded polypropylene inner core fully wrapped in matching upholstery for a seamless finish. Functional design is tailored to all-day seated use. The chair offers pneumatic seat height adjustment via a convenient side lever, unrestricted 360-degree swivel, and a synchro-tilt mechanism that supports backward recline with adjustable tension and a multi-position lock to secure preferred seating angles. Five dual-wheel casters enable smooth omnidirectional movement across hard floors and low-pile carpet, while the contoured mid-back shape delivers built-in lumbar support aligned to the natural lower back curve, and padded fixed armrests position forearms at a height compatible with standard desk surfaces. The chair is rated to support up to 150kg of static user weight for 8 hours of daily use. This model fits a wide range of spaces, including private executive and manager workstations, boardrooms and conference areas, home office studies, open-plan shared task zones, and professional reception areas where guest seating requires a polished appearance. It pairs seamlessly with 2.4m executive desks and aligns with contemporary commercial office decor schemes. For procurement planning, note that each chair ships across two cartons, with an 40 minutes of assembly time per unit. Logistics metrics support efficient bulk shipping for large fit-out projects, and the easy-clean artificial leather upholstery reduces ongoing maintenance demands for high-traffic deployments.
