Product Description

The Black High-Back Mesh Ergonomic Office Chair with Headrest, model ERG-MESH-HB-01, offers a streamlined task seating solution for professional and home settings. Its upright, high-back silhouette combines a gray-black woven mesh backrest tensioned within a black molded polymer frame, a contoured upholstered seat, fixed T-shaped armrests, and a matching framed mesh-and-foam headrest. A fixed padded lumbar band with black fabric or foam facing provides a defined support zone, while the five-star nylon base and twin-wheel casters give the chair a balanced, mobile profile. Overall dimensions are 650 by 650 by 1290 millimeters, with a clear width of 540 millimeters between the armrests. Construction centers on breathable mesh for the back, molded polyurethane foam for the seat, and black polymer components for the frame, arm pads, and headrest support bracket. The seat cushion uses 80 millimeters of molded foam with black woven upholstery, paired with a finished cushion thickness of 90 millimeters; the backrest padding thickness is 70 millimeters. Beneath the seat, a steel tilt plate and steel gas lift connect the seating structure to the nylon base. Product specifications list seat foam density at 45 kilograms per cubic meter, back mesh tensile target at 180 newtons per 50 millimeters, fabric abrasion resistance at 50,000 Martindale cycles, gas lift durability at 100,000 height-adjustment cycles, and caster rolling durability at 100,000 cycles. Functionally, the chair supports everyday desk work through pneumatic seat-height adjustment with a 100 millimeter stroke controlled by the visible right-side lever. Its synchro-tilt mechanism reclines to 118 degrees and locks in three positions, while a rear rotary knob adjusts back-recline resistance. The 360-degree swivel seat and five twin-wheel casters allow easy movement around a workstation. The recommended user weight capacity is 135 kilograms, and the chair has a net weight of 16.5 kilograms. This model is appropriate for individual office workstations, open-plan desks, home offices, study rooms, and shared computer desks where a neutral black finish and compact 650 millimeter footprint are preferred. Buyers should note that fixed armrests limit width and positioning flexibility, plan for assembly time of 40 minutes per set, and allow receiving and storage space for two cartons with a packaged gross weight of 23 kilograms per set.
