The Black Upholstered Mid-Back Office Task Chair with Fixed Arms is an unbranded model OC-MB-PU-001 under the office task chair category, presenting a sleek, uniform black aesthetic that fits both professional and casual work settings. Its mid-back silhouette is paired with fixed armrests and a classic 5-star base, creating a compact, balanced profile that works seamlessly with standard desk configurations. Built for reliable daily use, the chair features black PU leather upholstery with a smooth matte finish, stretched over high-density polyurethane foam padding supported by a plywood inner frame. The structural core includes a black powder-coated steel 5-leg base, a chrome-plated steel Class 3 gas lift, and a steel butterfly tilt mechanism under the seat. Fixed armrests use a black polypropylene frame with integrated arm pads, while 60 mm dual-wheel nylon casters with black hoods provide mobility. All visible seams feature precise top-stitching for a clean, finished look. Functionally, the chair supports core office seating needs with a pneumatic seat height adjustment controlled by a right-side lever, 360-degree continuous swivel, and synchronized seat-to-back tilt with tension adjustment via a built-in knob. The fixed armrests deliver consistent forearm support, while the 5-point star base distributes user load evenly for stable static positioning. The nylon casters roll smoothly on hard floors and low-pile carpet, supporting frequent relocation across workspaces. This chair fits a wide range of commercial and residential spaces. It works well for general office workstations and open-plan desks, as well as conference and meeting rooms where its easy-to-clean PU surface and consistent appearance support unified room setups. It is also suitable for home offices and study spaces, training rooms and shared seating areas, front-desk and reception guest areas, and private executive office workstations, adapting to use cases from short guest stays to extended daily work sessions. For procurement planning, the chair ships in a disassembled configuration, with assembly completed using included tools. Procurement teams should confirm material specifications, load ratings, and component certifications directly with the supplier, as referenced material densities, frame thicknesses, and performance values are standard category benchmarks for this product type.
