Product Description

The Black High-Back Mesh Ergonomic Swivel Office Chair with Headrest is an unbranded task chair, model OC-HBM-860-640, designed for seated work where back, head, and arm support are priorities. Its appearance is defined by a black tensioned mesh back set in a black polymer outer frame, a matching upholstered seat, and a curved padded headrest mounted to the upper back frame. Fixed black polymer loop armrests with integrated side supports frame the seat, while a black nylon five-star base and five black PU twin-wheel casters give the chair a coordinated office profile. The chrome-finish steel gas-lift tube is paired with a black telescopic sleeve, and the chair swivels around this central support axis. Overall dimensions are 680 by 640 by 860 millimeters, with 540 millimeters of clear width between the armrests. The 240-millimeter lumbar support zone, 70-millimeter backrest padding thickness, and high-back form provide a structured sitting surface. The seat uses a black upholstered cushion with a molded foam core, 45 kilograms per cubic meter foam density, 80 millimeters of seat foam, and a finished cushion thickness of 90 millimeters. The back mesh fabric is 2.2 millimeters thick and has a fabric abrasion acceptance value of 50,000 Martindale cycles. A steel gas lift and nylon frame and base complete the primary construction. Functionally, a pneumatic lever adjusts seat height from 440 to 540 millimeters using a 100-millimeter stroke. The chair offers 360-degree swivel movement, and its tilting mechanism provides an 18-degree back recline, tension control, and one lock position. Twin-wheel casters on the 680-millimeter five-star base support rolling movement between work areas. The recommended user weight capacity is 135 kilograms, and net weight is 17 kilograms. This model is suited to individual desks in open offices, home offices, and administrative workstations involving 8-hour seated work. It is also appropriate for task seating in meeting rooms, reception back offices, and shared workpoints where swivel, mobility, and adjustable seat height are useful. Procurement planning should account for one set supplied in two cartons, a packaged gross weight of 23 kilograms, carton volume of 0.26 cubic meter per set, and a reference assembly time of 40 minutes per set.
