打开导出工具The Yiankang model 1721B-X01 is a mid-back swivel conference and task office chair defined by a crisp two-tone visual profile, pring a smooth white molded high-impact polypropylene outer shell that forms integrated fixed loop armrests with rich burgundy PU faux leather upholstery accented by matching edge stitching. Its clean, structured silhouette balances a contoured mid-height backrest with a generously proportioned seat, anchored by a polished die-cast aluminum five-star base fitted with black dual-wheel casters for a polished, contemporary look suited to both professional and residential environments. Construction centers on durable multi-layer support structures, with molded plywood internal support frames for the seat and back, wrapped in high-density polyurethane seat foam and medium-density back foam to deliver consistent, supportive padding. The polished aluminum base connects to a chrome-plated steel class 3 pneumatic gas lift, paired with a powder-coated steel tilt mechanism controlled by black nylon-coated steel levers positioned under the seat. Dual-wheel nylon casters with PU treads are engineered to move smoothly across hard flooring and low-pile carpet without causing surface damage. Functional features are tailored to flexible, comfortable use: a left-side lever controls pneumatic seat height adjustment to align with varying desk heights and user leg lengths, while a right-side lever activates a 12-degree synchro-tilt function with a lockable upright position to support both focused work and relaxed recline during long meetings. Full 360-degree swivel rotation enables easy access to surrounding work surfaces, and the fixed integrated armrests sit at an ergonomic height to support relaxed elbow positioning. The contoured mid-back delivers targeted lumbar support for upright seated postures without an attached headrest. This chair fits a wide range of spaces, including executive private workstations, corporate conference and boardrooms, open-plan coworking offices, modern home study areas, office guest seating zones, and premium hospitality executive lounges. Its compact footprint and stylish two-tone finish complement modern decor schemes across commercial and residential settings. For procurement teams, key considerations include reviewing final supplier material documentation to confirm exact material grades and component certifications before bulk purchase. Logistics planning can account for knocked-down packaging that supports efficient contner loading, with straightforward on-site assembly per unit. The chair carries a recommended commercial use warranty of three years, with durable upholstery rated to withstand frequent dly use in high-traffic environments, making it a versatile option for both long-term dedicated workstations and flexible shared seating layouts.
