The Black High-Back Mesh Ergonomic Office Chair with Retractable Footrest, model ERG-MESH-FR-001, is an unbranded task seating solution designed to balance supportive comfort and functional flexibility across long periods of seated use. Its streamlined high-back silhouette presents a professional, understated black finish that integrates seamlessly with a range of interior design schemes, with a structured five-star wheeled base supporting smooth swivel movement for easy repositioning. The chair is built for durable, long-term use, with a core frame combining reinforced steel and nylon-glass fiber composite components. The backrest is upholstered in tensioned breathable polyester mesh to promote consistent air circulation, while the seat pairs breathable mesh surfacing with high-density molded foam cushioning. Soft PU-padded armrests sit atop reinforced nylon supports with steel height adjustment posts, and the 2.5mm thick powder-coated steel five-star base is fitted with smooth PU casters for floor-friendly mobility. A Class 3 steel gas lift supports reliable height adjustment, and the retractable footrest features a steel support frame with a padded mesh surface for comfortable leg support. Targeted ergonomic adjustments allow users to customize fit for individual preference: pneumatic seat height adjustment is controlled via a right-side lever, the backrest tilts to 135 degrees with four lockable recline positions, and adjustable tilt tension lets users tailor recline resistance to match their weight. The 3D armrests adjust vertically, front-to-back, and side-to-side, while the adjustable headrest shifts vertically and tilts for customized neck support. A contoured lumbar pad moves vertically to align with the user’s lower back, and the pull-out footrest extends and flips up to support reclined resting. This chair suits a broad range of residential and commercial spaces, including home office workstations, corporate open plan offices, private study rooms, conference meeting spaces, and home gaming or media setups. It supports eight or more hours of daily computer work, accommodates short workday naps when reclined, and offers smooth mobility to let users turn easily toward presentation screens or meeting speakers. Procurement teams should note that each unit ships across two cartons, with an 40 minutes of assembly time per set. The chair supports users up to its maximum static weight capacity, and fits users up to its maximum suitable height, making it a flexible option for shared work environments where multiple users will access the seating on a rotating basis.
