Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest, model OC-HBM-GRY-01, presents a coordinated grey task-seating solution for professional and residential workspaces. Its tall back is framed by a rounded grey polymer structure surrounding a flexible grey mesh panel with a woven open surface. The headrest uses a matching mesh cushion with a rounded polymer edge and central support, while the padded grey upholstered seat softens the functional form. Light grey vertical arm supports, molded side brackets, soft-touch or upholstered arm pads, and a five-star radial base complete the structured visual layout. Overall dimensions are 680 by 660 by 1260 millimetres, with a finished seat cushion thickness of 90 millimetres, backrest padding thickness of 70 millimetres, a 240-millimetre lumbar support zone, and 540 millimetres of clear width between the armrests. Construction combines a mesh back, upholstered padded seat, plastic arm pads, painted metal or glass-filled nylon base, gas lift, and nylon casters. The seat uses an 80-millimetre foam core beneath the finished cushion, set into a grey molded polymer carrier connected to the control mechanism. The black telescoping steel gas-lift column supports the seat and connects to the light grey painted five-star base. Material references include 45 kilograms per cubic metre seat foam density, 40 percent seat foam rebound, 50,000 Martindale cycles for back mesh abrasion, and 60,000 Martindale cycles for seat fabric abrasion. The chair is intended for users up to 150 kilograms and has a net weight of 18 kilograms. Functional features support active desk use. A visible side lever operates pneumatic seat-height adjustment through 100 millimetres of travel. The seat rotates 360 degrees around the central column, and the back offers reclining tilt movement with a 15-degree maximum recline and an upright lock position. A rotary tension control allows adjustment for user weights between 50 and 150 kilograms. The headrest is height-positioned to support the neck at 1260 millimetres from the floor, while arm pads sit 230 millimetres above the seat for forearm support. Five 60-millimetre twin-wheel casters provide mobility on hard floors or low-pile carpet. This model suits open-plan office workstations, home offices used for daily desk work, meeting and task rooms, shared administrative desks, reception areas, and computer-based roles involving keyboard, document, and monitor tasks. Procurement teams should note the neutral grey appearance, swivel and mobile design, shift-sharing suitability, and flooring requirements. For scratch-sensitive floors, the soft-wheel option should be specified. Each set ships in two cartons with a packaged gross weight of 23 kilograms, a reference carton volume of 0.26 cubic metre, and a reference assembly time of 40 minutes. The indicative 20GP loading figure is 135 sets at 85 percent space utilization, useful for bulk workplace or residential project planning.
