Product Description

The High-Back Ergonomic Mesh Office Chair with Headrest is an unbranded task seating solution designed for sustained desk use. Model EOC-MESH-HB-GR-LM combines a tall supportive profile with a mobile five-star base, giving commercial and residential workspaces a practical chair for computer work, administrative tasks, and general office seating. Its grey mesh back and green upholstered seat create a distinct two-tone appearance, while the curved headrest, fixed T-arms, and polished chrome base contribute a clean, functional look suited to modern interiors. Visually, the chair is defined by a high backrest formed from flexible grey mesh stretched over a framed ergonomic Y-shaped support. The mesh-facing padded headrest follows a curved top profile and extends the upper-back structure to provide a resting area behind the head. Below, the green fabric seat is paired with light-grey fixed armrests topped with molded polymer pads. The chrome-plated five-star metal base and black twin-wheel casters complete the streamlined workplace aesthetic. The overall layout centers the seat on a telescopic gas lift, allowing the back, headrest, arm support, seat, and base to work as a coordinated ergonomic system. Construction uses breathable mesh for the back, upholstered foam for the seat, molded armrest components, a chrome-plated metal base, nylon casters, and a steel gas lift. The cushion uses molded foam over a plywood or molded seat shell, with a finished cushion thickness of 90 mm. The backrest includes padded support and a defined lumbar support zone. The fixed T-arms offer a consistent arm position, with clear spacing between them for ease of entry and exit. Functionally, the chair supports pneumatic seat-height adjustment through a 100 mm stroke using the visible right-side lever. A synchro-tilt mechanism coordinates 18 degrees of back recline with 5 degrees of seat movement; purchasers should confirm available lock positions directly with the supplier. The seat rotates through 360 degrees for workstation access, while the five-star caster base provides rolling movement on hard or carpeted floors. The recommended user weight capacity is 135 kg. This model is appropriate for individual desks, computer workstations, administrative seats, open offices, meeting rooms, and home offices where head, lumbar, arm support, and breathable seating are required. Procurement teams should plan for assembly, with a reference time of 40 minutes per set. The product is supplied as one set across two cartons, with a packaged gross weight reference of 23 kg and a reference carton volume of 0.26 cubic meters per set. Buyers should also verify finish, recline lock options, caster suitability for the intended floor, warranty terms, and replacement-part availability before ordering.
