Product Description

The Black High-Back Mesh Ergonomic Office Chair with Headrest, model OC-MESH-HB-HR-01, presents a professional task-chair form with a tall black-framed backrest, woven mesh central panel, and dedicated lower lumbar zone. A curved black mesh headrest on a molded outer shell continues the streamlined silhouette, while the black upholstered molded-foam seat uses a rounded waterfall front edge. Black molded T-shaped fixed arm supports with flat padded pads frame the seat, and the polished aluminum five-star base gives the chair a refined contrast against the black upper structure. Overall dimensions are 660 by 650 by 1280 millimeters, with 540 millimeters of clear width between the armrests. The seat cushion has a finished thickness of 90 millimeters, backrest padding is 70 millimeters thick, and the lumbar support zone is 240 millimeters high. The chair has a net weight reference of 18 kilograms. Construction combines breathable mesh, padded support, and durable structural components. The back and headrest use black mesh, while the seat is upholstered in black fabric or mesh over molded foam with a 45 kilogram per cubic meter foam density. Armrests and mechanism covers are plastic, the tilt mechanism uses black steel and polymer, the gas lift is chrome finished, and the five outward-spreading base legs are polished aluminum. Mobility is provided by nylon casters. A tension knob beneath the seat controls the recline mechanism. Functional adjustment is centered on daily workstation comfort and movement. A pneumatic lever raises or lowers the seat through a 100 millimeter stroke to a 550 millimeter seat height. The chair swivels 360 degrees around the central gas-lift axis, and the multi-position synchro-tilt mechanism offers an 18-degree maximum back angle with tension adjustment. The height-adjustable curved headrest supports the neck and upper spine. Its recommended user weight capacity is 150 kilograms. The product reference data also includes a 900 kilogram static seat verification load, 120,000-cycle backrest cyclic test target, and 100,000-cycle targets for gas-lift operation and caster rolling durability. This chair suits open-office workstations, executive desks, managerial workstations, shared desks, and home-office settings designed for 8 hour computer work. Its neutral black appearance and polished base fit both collaborative commercial floors and more formal private offices. For procurement, the unbranded model is appropriate where swivel mobility, standardized replacement parts, and consistent task seating are priorities. Each set is supplied in two cartons, with a reference packaged gross weight of 23 kilograms and reference carton volume of 0.26 cubic meter; planners should allow a reference assembly time of 40 minutes per set.
