Product Description

The Black Mesh Ergonomic Office Chair with Adjustable Headrest and Fixed Armrests is a high-back task chair with a clean, neutral appearance suited to professional and residential work settings. Its black finish creates a coordinated look across the mesh back, headrest, frame, armrests, base, and casters. The tall back uses flexible mesh tensioned within an ergonomic outer support, while a padded flexible lumbar panel is integrated into the lower back area. A curved headrest with a black mesh center and polymer frame extends the supportive profile, and rigid T-shaped armrests provide simple, fixed side support with flat pads. The chair has an overall envelope of 650 by 650 by 1290 millimeters, with a 540-millimeter clear width between armrests. Construction combines a fabric-upholstered foam seat, black nylon or steel framing, steel connector brackets, a painted metal five-star base, and twin-wheel nylon casters. The seat uses black woven fabric over cut or molded polyurethane foam. The finished cushion thickness is 90 millimeters, with an 80-millimeter foam specification and 45 kilogram per cubic meter foam density. The backrest padding specification is 70 millimeters, and the lumbar support zone height is 240 millimeters. Material and component acceptance references include 50,000 Martindale cycles for the back mesh fabric, 100,000 rolling cycles for the casters, and 100,000 height cycles for the gas lift. Recommended user weight capacity is 136 kilograms, and net weight reference is 16.5 kilograms. Daily operation is supported by pneumatic seat-height adjustment through a lever, a 360-degree swivel around the central gas lift, and a synchro-style tilt mechanism. Recline reaches 118 degrees, and a side tension knob allows tilt resistance to be adjusted. The headrest offers 80 millimeters of height adjustment and pivots to support the neck. These features make the chair appropriate for individual desk-based work requiring breathable back support, easy movement, and adjustable posture. The model EMC-MESH-HR-BLK-01 is an unbranded ergonomic office chair suitable for open offices, private workstations, home offices, and meeting rooms where a black neutral task chair is preferred. Procurement teams should plan for one set supplied in two cartons, packaged gross weight of 23 kilograms, 0.26 cubic meter carton volume, and a reference assembly time of 40 minutes per set. A 20-foot general-purpose container indication is 135 sets at 85 percent space utilization. Buyers should also confirm fixed armrest compatibility with desk dimensions and review assembly, replacement component, and delivery terms before ordering.
