Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest and Adjustable Arms, model ERG-HBM-01, is an unbranded task chair designed for individual desk work. Its tall black mesh back creates a light, open appearance while the curved mesh headrest provides a coordinated upper profile. A molded polymer frame and black side body shape the backrest, with structural support concealed within. The chair has an overall dimension of 660 by 660 by 1280 millimeters, a finished seat cushion thickness of 90 millimeters, backrest padding thickness of 70 millimeters, a lumbar support zone height of 240 millimeters, and a clear width of 540 millimeters between armrests. The T-shaped armrests use fixed-height molded polymer posts with flat polymer pads, offering 240 millimeters of vertical support and lateral forearm contact. Construction combines a black woven flexible mesh back and headrest with a molded foam seat upholstered in black fabric or mesh-facing material. Plastic components form the arms and frame, while the five-star base is made of black glass-fiber-reinforced nylon and fitted with black nylon twin-wheel casters. The chrome-plated gas lift provides height control. Functional features include pneumatic seat-height adjustment through a visible right-side lever, with a 100 millimeter stroke. A synchronized seat-and-back tilt mechanism uses a rear tension knob and permits 18 degrees of maximum back travel. The seat swivels 360 degrees and moves on five dual-wheel 60 millimeter casters intended for carpet or hard-floor use. The published user weight capacity is 136 kilograms. Verification targets include a 680 kilogram static seat load, 120,000 backrest cycles, 100,000 seat-sliding cycles, and 100,000 caster-rolling cycles. The chair is suited to full-day office workstation tasks requiring head, lumbar, arm, and swivel support. It also fits conference rooms, manager workstations, and home offices using standard 760 millimeter desk heights. 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 kilograms per set, carton dimensions are 850 by 420 by 720 millimeters, and carton volume is 0.26 cubic meters. The indicative 20GP loading quantity is 135 sets at 85 percent space utilization.
