Product Description

The High-Back Black Mesh Ergonomic Executive Office Chair is a professional seating solution with a streamlined black exterior and a tall, structured silhouette. Its high backrest uses flexible black engineered mesh tensioned over a curved polymer and steel perimeter frame, creating a breathable support surface with a contoured appearance. A black polymer Y-frame with a polished chrome side spine connects the back to the seat mechanism, while the polished die-cast aluminum five-star base adds a refined metallic contrast. The chair presents a practical executive look suited to interiors where understated black finishes and polished hardware are preferred. Construction combines upholstered comfort with durable structural components. The seat features a black mesh surface over a molded foam cushion supported by a polymer load plate, and the backrest includes padded depth within its tall support zone. Armrests use height-adjustable black steel or aluminum posts topped with soft black polymer pads. The central support is built around a black steel synchro-tilt mechanism with paddle levers and a tension housing, while the seating system is completed by a steel gas lift and black twin-wheel nylon casters set into the aluminum base. Functional features are designed for extended desk-based work. The pneumatic right-side lever adjusts seat height through an 80 mm travel range, supporting use with 530 mm desk heights. The synchro-tilt mechanism allows the back to recline to 125 degrees from the horizontal seat plane, while the seat moves in unison to a 5-degree rearward angle. Users can select from four back tilt lock positions. The arm posts provide 70 mm of vertical adjustment, and the padded arm surfaces support a relaxed shoulder position. A 360-degree swivel seat and five casters allow smooth movement within a workstation area. The listed weight capacity is 150 kg, and the maximum recommended user height is 190 cm. This model is appropriate for executive offices, managerial workstations, knowledge-worker environments, open offices, meeting rooms, and home offices. It is especially relevant where high-back support, breathable mesh, and mobility are priorities. For project procurement, buyers should confirm the gas lift, caster durability, and fabric performance documentation with the supplier, particularly when specifying multiple chairs for commercial settings. The product is supplied unbranded and flat packed; logistics information includes one set, a packaged gross weight of 23 kg, and a reference assembly time of 40 minutes per set.
