The Yiankang Model 1716C-X12 Armless Swivel Height-Adjustable Upholstered Office Chair presents a sleek, streamlined profile defined by its light blue smooth faux leather upholstery, polished chrome central column and stationary 4-star base. The mid-back contoured design pairs with a curved, waterfall-edge seat pan to create a compact, unobtrusive visual footprint, with no protruding armrests to break its clean lines. The unit balances soft padded surfacing with reflective metal accents for a contemporary, professional aesthetic. Constructed with multi-layered supportive structures, the chair features high-resilience polyurethane foam in the seat and molded polyurethane foam in the backrest, mounted on bent plywood internal support frames connected via a black powder-coated steel connection plate to a polished chrome-plated steel base fitted with non-marking black rubber foot pads. A polished chrome-plated steel Class 3 gas lift supports height adjustment, controlled by a side-mounted black reinforced nylon lever, with durable upholstery stitching and contract-grade faux leather built to withstand regular frequent use. Core functional features include pneumatic seat height adjustment that locks at any position within its travel range, full 360-degree horizontal swivel for flexible positioning without base movement, and contoured ergonomic shaping that reduces thigh pressure and delivers targeted lumbar support for upright task seating. The fixed, caster-free base delivers stable, non-slip placement, while the armless configuration allows unobstructed side access and easy tucking under work surfaces. The chair uses tool-free knock-down assembly that can be completed quickly upon delivery. This model is well suited for a range of both commercial and residential spaces, including open office workstations, meeting and conference rooms, reception and guest waiting areas, flexible training rooms, compact home office setups, and residential vanity or dressing areas. Its slim profile fits neatly around standard tables and desks, its easy-to-clean upholstery suits high-traffic public zones, and its lightweight build supports quick reconfiguration for multi-purpose spaces. For procurement planning, note that the chair ships in knock-down form for efficient transport, with bulk contner loading calculated to support large-scale commercial furnishing projects. Buyers should confirm exact material composition, formal certification documentation, and final packaging configurations directly with the supplier prior to order placement, as some specification values reference standard category benchmarks rather than direct supplier measurement. The chair carries a recommended warranty period aligned with mid-market office seating offerings, supporting reliable long-term use across applicable settings.
