Product Description

The High-Back Black Mesh Ergonomic Office Chair with Headrest, model EM-HB-MESH-01, presents a structured, professional seating solution under an unbranded product line. Its visual form is defined by a tall black mesh backrest, contoured frame, integrated headrest, padded armrests, and a five-star mobile base. The layout follows a conventional ergonomic office chair silhouette, with the breathable mesh back rising to support the upper back and head while the upholstered seat provides a cushioned work surface. The backrest uses black flexible woven mesh tensioned over an injection-molded black nylon frame with integrated side supports. This construction gives the back a supportive, open surface while retaining a uniform black appearance. The seat combines black woven fabric upholstery with molded polyurethane foam at 45 kg/m3 density and 60 mm crown thickness, producing a finished cushion thickness of 90 mm. Beneath the cushion is a 12 mm glass-fiber-reinforced polypropylene load plate. Armrests use height-adjustable black nylon posts fitted with soft polymer pads, while the chair sits on a nylon five-star base with twin-wheel casters. A steel mechanism and gas lift form the central control and height system. Functional adjustment is a core part of the design. The pneumatic seat-height lift offers 80 mm of travel, controlled by a right-side lever, with seat height adjustable from 460 to 540 mm. The synchro-tilt mechanism allows the backrest to recline 18 degrees while the seat tilts 7 degrees, and the chassis can be locked in four positions. A sliding seat pan provides 50 mm of forward travel for different thigh lengths, and the curved headrest moves 80 mm vertically and rotates 30 degrees for neck support. The clear width between armrests is 540 mm, and the 240 mm lumbar support zone is positioned within the high-back structure. This chair is suited to office workstations used for computer operation, focus tasks, and full desk shifts, as well as meeting spaces, executive desks, shared workstations, and home offices. Its swivel base and casters support mobility within these settings. Procurement planning should account for delivery as one set packed in two cartons, with a packaged gross weight of 23 kg per set and reference assembly time of 40 minutes per set. The overall dimensions are 680 x 680 x 1260 mm, and the chair has a net weight of 18.5 kg. Buyers should also note the 150 kg recommended user weight, seat static load rating of 200 kg, backrest dynamic load rating of 136 kg, and 100,000-cycle ratings for both caster rolling durability and gas lift operation.
