Product Description

The Grey Mesh High-Back Ergonomic Office Chair with Headrest presents a clean, professional silhouette defined by breathable grey woven mesh, a tall framed back, and a polished aluminium five-star base. Black polymer armrests, mechanism housing, casters, and support brackets provide a visual contrast with the grey upholstery while maintaining a coordinated commercial appearance. Its high-back form includes a curved, padded headrest and a defined lumbar support zone, giving the chair a structured profile suited to focused seating at desks and computer workstations. The armrests frame the seat with a clear between-arm width of 540 mm, while the overall dimensions are 680 x 680 x 1240 mm. Construction combines a tensioned mesh backrest with a molded polyurethane foam seat cushion featuring contoured edge support. The seat surface uses grey woven mesh or mesh-textured fabric over the cushioning, which has a finished thickness of 90 mm, while the backrest padding thickness is 70 mm. The lumbar support zone measures 240 mm in height. Black polymer arm pads are mounted on height-adjustable support posts, and the under-seat tilt mechanism uses black steel-reinforced polymer. Mobility and height support are provided by a chrome gas lift, polished aluminium base, and black twin-wheel casters. The chair is built for adjustable task seating. A pneumatic lever controls seat height through a 70 mm stroke, setting the seat between 460 mm and 530 mm. Its synchronous recline allows the seat and back to tilt together, with a maximum back angle of 122 degrees and a position lock. A rear rotary knob adjusts tilt resistance to suit the user, while the bracket-mounted headrest offers 70 mm of height adjustment and pivoting neck-angle support. These functions support full-time desk work, computer tasks, and document review, as well as private executive offices and premium home-office settings where grey mesh and polished metal detailing are preferred. Rated for a recommended user weight of 150 kg, the chair has a net weight of 21 kg, a Class 4 gas lift, and a base static load rating of 1136 kg. Published durability values include 100000 caster rolling cycles, 100000 seat-height adjustment cycles, and 300000 back-rest cyclic durability cycles. Procurement teams should plan for assembly, with a reference time of 40 minutes per set. The product is supplied as one set across two cartons, with a packaged gross weight of 23 kg and a reference carton volume of 0.26 m³ per set. Buyers should also confirm site flooring, delivery access, and assembly responsibilities before ordering.
