The YUXIANG Mid-Back Black Faux Leather Ergonomic Office Task Chair, model OF-CH-MB-PU-660, presents a polished, professional silhouette tailored for both commercial and residential seated work environments. Its compact, proportional form is anchored by a polished chrome-plated five-star base fitted with black twin-wheel casters, paired with a contoured mid-height backrest and structured padded seat that aligns with standard desk configurations. The matte black PU upholstery is complemented by chrome-finished metal components and padded armrests, delivering a sleek, understated aesthetic that blends seamlessly across formal and casual workspaces. Constructed for consistent daily use, the chair features 1.0mm thick matte black PU faux leather upholstery over high-density molded polyurethane padding for both the seat and backrest. The seat incorporates a waterfall front edge designed to reduce pressure on the backs of the thighs, while the contoured backrest is shaped with a built-in lumbar support curve. Its structural components include a 1.5mm thick chrome-plated steel five-star base, Class 3 steel pneumatic gas lift cylinder, 2.5mm thick stamped steel tilt mechanism, reinforced nylon armrest support posts, 12mm thick molded plywood internal seat frame, and 50mm twin-wheel nylon casters suitable for both carpet and hard floor surfaces. Functional features support flexible, ergonomic use across varied work tasks. A side-activated lever controls pneumatic seat height adjustment with a 70mm stroke that locks at the user’s selected height, while armrests offer 70mm of vertical adjustment to lock into place for customized arm support. The backrest delivers a maximum 12-degree recline with stepless tension adjustment to match user weight, plus an upright lock to hold the backrest in position for focused work. Full 360-degree swivel around the central column allows easy access to surrounding desk surfaces, and the dual-wheel casters enable smooth, quiet movement across flooring types. This chair is well suited for private office workstations supporting 8 hours of daily seated work, open plan cubicle and benching layouts, compact home office workspaces, conference room auxiliary seating, co-working hot desks, and reception areas where a professional, easy-to-clean seating surface is prioritized. For procurement planning, note that each unit ships in two cartons, with an assembly time of 40 minutes per set. The chair has a recommended user weight capacity of 136 kg, and its compact footprint supports efficient space utilization for bulk orders. The durable, stain-resistant faux leather surface simplifies maintenance between users in high-turnover shared spaces.
