Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest, model EH-HBM-01, presents a professional executive-style seating solution with a structured black aesthetic suited to both commercial and residential work environments. Its tall mesh backrest is shaped over a contoured polymer frame and integrated with a padded fixed headrest, creating a continuous upright form intended to support the neck and upper body. The black color scheme is carried through the back frame, armrests, mechanism housing and upholstered seat, while the polished chrome-plated metal five-star base provides a contrasting visual anchor. Five nylon twin-wheel casters are arranged radially beneath the seat for a balanced mobile footprint. Construction combines flexible woven mesh with molded and reinforced components. The back uses black flexible woven mesh supported by a contoured polymer frame, with a defined lumbar support zone and padded backrest section. The seat features molded polyurethane foam beneath black woven upholstery, supported by a molded polypropylene load-bearing shell. Fixed polymer T-arms include padded tops and molded side support brackets. The base is a polished die-cast aluminum or chrome-plated steel radial structure, paired with a steel gas lift and center column. The chair is rated for a recommended user weight capacity of 136 kg and has a net weight of 18.5 kg. Functional features support everyday desk use. A pneumatic seat-height lift provides 80 millimeters of travel through an underside lever and uses a target Class 4 cylinder. The synchronized seat-and-back tilt reclines to 120 degrees, offers multi-position locking, and includes a side tension knob. A 360-degree swivel and five dual-wheel casters allow movement across carpet or hard-floor surfaces. The fixed headrest and T-armrests provide neck and forearm support, though the armrests do not adjust in width, height or pivot. This model is appropriate for open-plan workstations, executive desks and home offices, especially for users seeking neck, lumbar and forearm support during long periods of seated work. It can be procured as a single executive chair or in volume for worker seating. Buyers specifying hard-floor installations should request floor-protection soft casters. Delivery is configured as one set across two cartons, with a packaged gross weight of 23 kilograms and a reference assembly time of 40 minutes per set.
