Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest and Adjustable Arms is a professional seating solution with a structured, contemporary appearance. Its gray mesh back and matching headrest create a light visual profile, while the black fabric-covered foam seat, arm components, outer back frame, and five-star base provide a contrasting commercial finish. The contoured high back is framed to support the mesh as a ventilated elastic surface, and the curved mesh-faced headrest is mounted by a central black bracket. The T-shaped arm supports sit either side of a 540 mm clear armrest width, giving the chair a balanced layout suited to standard desk settings. Construction combines a molded back frame, upholstered foam cushion on a molded support shell, steel gas lift, molded base, and twin-wheel nylon casters. The finished seat cushion is 90 mm thick, the backrest padding zone is 70 mm thick, and the lumbar support area is 240 mm high. Buyers should note that several material details, including back mesh yarn type, headrest internals and hardware, seat fabric weave and flame rating, and exact plastic or nylon formulations for arms, frame, base and casters, require bill-of-materials confirmation before formal specification. Functional features support everyday desk use. A right-side under-seat lever controls pneumatic height adjustment through a 90 mm stroke. The synchro-tilt mechanism allows a 15-degree backrest recline with synchronized seat movement and tension control, while a multi-position tilt lock secures the chair upright or at selected reclined angles. The seat rotates 360 degrees and moves on five twin-wheel swivel casters for use on hard floors and low-pile carpet. The listed weight capacity is 150 kg, and the chair is fitted with a Class 4 gas lift. This model is appropriate for office workstations used by desk-based staff, engineers, and administrators, as well as private offices, open-plan work areas, meeting spaces, and home offices where prolonged computer work, head support, and recline capability are desired. Overall dimensions are 670 x 660 x 1300 mm. For procurement planning, the chair is supplied as one set across two cartons, with packaged gross weight of 23 kg per set, carton volume of 0.26 cubic meters per set, and a reference assembly time of 40 minutes per set. Specification reviews should confirm site flooring, desk-height compatibility, assembly responsibility, warranty terms, replacement parts availability, and the unresolved bill-of-materials details before bulk ordering.
