Product Description

The Ergonomic High-Back Mesh Office Chair with Adjustable Headrest (model OFC-MESH-ERG-001) is an unbranded office task chair designed for balanced support and versatile use across work environments. Visually, it features a streamlined, professional profile with a consistent matte black finish across its frame, base, and fabric components, structured to pair unobtrusively with both commercial and residential interior palettes. Its layout prioritizes ergonomic alignment, with a tall contoured backrest, centrally positioned lumbar support zone, padded fixed armrests, and an adjustable headrest positioned to cradle the neck during seated work. Built for regular commercial and personal use, the chair combines durable, purpose-selected materials: a breathable woven elastic mesh tension surface for the backrest, supported by an injection-molded black nylon frame; a 90mm thick seat cushion made of high-resilience polyurethane foam wrapped in wear-resistant black woven fabric, set on a 12mm thick molded plywood inner frame; a reinforced injection-molded black nylon five-star base fitted with PU dual casters; and a Class 3 black powder-coated carbon steel gas lift. The headrest uses molded polyurethane foam with a matching fabric wrap, while armrests are constructed from fixed-height black nylon with soft PU padded tops for forearm comfort. Core functional features are tailored for long-duration sitting: 100mm of vertical seat height adjustment controlled via a side-mounted pneumatic lever, a synchro-tilt backrest with 12-degree maximum recline and single-position lock, a rotary under-seat knob to adjust tilt tension to match user weight, 360-degree swivel rotation, and free-rolling casters for easy movement. The segmented flex slat lumbar support conforms to natural spine curvature during recline, while the headrest offers both vertical height adjustment and 30-degree pivot adjustment to customize neck support. The mesh back promotes air circulation to reduce heat buildup during extended use. This chair is suitable for a wide range of spaces: private offices, where it supports 8 hours of daily executive or staff desk work; open-plan workstations, as it fits standard desk footprints and allows easy movement between tasks; home offices, where its neutral black finish complements residential decor for remote work; conference rooms, where its adjustable height aligns with standard table heights; shared hot-desking spaces, thanks to its durable commercial-grade construction that tolerates frequent adjustment and user rotation; and training rooms, where the wheeled base enables quick space reconfiguration and breathable mesh maintains comfort during long sessions. For procurement, note that each unit ships in two cartons, with a reference assembly time of 40 minutes per set. It supports a maximum recommended user weight of 136 kg, with durable component ratings suited for high-traffic commercial use, and fits standard 20-foot container loading for bulk orders at documented space utilization rates.
