Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest and Fixed Armrests is a gray task seating solution designed for full-day computer work. Its high-back form pairs a breathable woven mesh backrest with a curved padded headrest, creating a structured profile suited to users seeking upper-back, shoulder, and neck support. The gray back and headrest contrast with black fixed armrests, a black external back frame, and a black five-star base, giving the chair a clean commercial-office appearance. The chair has an overall footprint of 670 by 680 mm and a total height of 1230 mm. The backrest uses flexible polyester mesh stretched over a polymer frame, while the seat combines gray upholstered molded foam with a rounded waterfall front and a black support shell. The finished cushion is 90 mm thick, using foam specified at 45 kg/m3 with 35% rebound, and the seat is supported by a 14 mm bent plywood or equivalent board. The backrest includes 70 mm of padding thickness and a lumbar support zone 240 mm high. Fixed molded polymer arm pads sit on angular polymer or painted metal support posts, with 540 mm of clear width between the armrests. Mobility and height control are provided by a central gas-lift pedestal, tilt mechanism, twin-wheel casters, and swiveling five-star base. The right-side lever controls pneumatic seat-height adjustment across a 100 mm stroke, with seat height ranging from 440 to 540 mm. The backrest reclines from 95 to 120 degrees, with a reference recline angle of 125 degrees and three suggested lock positions. The headrest is mounted on a rear bracket and offers 80 mm of height adjustment. The stated recommended user weight capacity is 135 kg, and the chair net weight is 17.5 kg. This model is appropriate for open offices, workstation clusters, home offices, and manager workstations. It is best configured with a desk 760 mm high and a monitor set at eye level. Because the armrests do not adjust in height or width, specifiers should assess whether fixed support matches the intended user group. Procurement teams should also confirm exact fabric, foam, base material, gas-lift class, steel thickness, and grease rating through the bill of materials and supplier documentation. Packaging is listed as one set across two cartons, with a packaged gross weight of 23 kg and reference assembly time of 40 minutes per set.
