Product Description

The Black Mesh Ergonomic Office Chair with Headrest, model EMH-MESH-01, presents a streamlined professional appearance through its coordinated black finish. A high-back profile, integrated headrest, contoured seat, T-shaped armrests, and five-star mobile base create a practical task-chair silhouette suited to everyday desk use. The open mesh surfaces give the chair a lighter visual presence than padded executive seating, while the molded frame and defined lumbar zone provide structured support. Its back is formed from black flexible mesh tensioned within an injection-molded black polymer frame. Internal Y-shaped support ribs reinforce the back frame, and the lumbar support zone is 240 mm high. The seat uses black mesh or a mesh-covered flexible seat plate over a contoured polymer support shell, with a finished cushion thickness of 90 mm and backrest padding thickness of 70 mm. The armrests combine black polymer vertical posts and T-shaped supports with soft-touch top pads. A black-painted steel mechanism, Class 4 gas cylinder, 50 mm lift, reinforced molded nylon five-star base, and twin-wheel casters complete the construction. The clear width between armrests is 540 mm, and overall dimensions are 660 x 680 x 1320 mm. Functionality is centered on adjustable ergonomic task seating. The right-side lever controls pneumatic seat-height adjustment with 100 mm of travel. A synchronized tilt mechanism allows the back to recline through 30 degrees, with tension adjustment and multi-position lock. The gas-lift center and caster base enable 360-degree swivel movement, while five dual-wheel casters provide mobility on carpet, tile, and hard floors with 360-degree stem rotation. Published ratings include a 150 kg recommended user weight capacity, 120 kg dynamic seat load, 500 kg static base load, and 100,000-cycle durability ratings for both caster rolling and tilt mechanism operation. The chair net weight is 18.5 kg. The model is appropriate for full-time office workstations involving computer and keyboard tasks, as well as executive desks, home offices, meeting spaces, and shared task areas where rolling access, airflow, and postural support are priorities. Its understated black appearance works across modern, functional, and mixed commercial interiors. Buyers should plan for assembly and receiving logistics: each set ships in two cartons, with a reference assembly time of 40 minutes. Packaged gross weight is 23 kg per set, carton dimensions are 850 x 420 x 720 mm, and the reference carton volume is 0.26 cubic meters per set. For bulk container planning, the indicative 20GP loading figure is 135 sets at 85 percent space utilization. As an unbranded chair, procurement review should focus on fit with intended users, flooring type, warranty terms, replacement parts, and assembly support rather than brand identity alone.
