产品描述

The Black High-Back Mesh Ergonomic Office Chair with Headrest, model U-EMH-650-BK, offers a practical seating solution for professional work settings. Presented in black without a branded label, its tall mesh profile, integrated headrest, padded seat and five-star base create a structured appearance suited to standard office interiors. The chair’s visual form is defined by a high black woven polyester mesh back and matching headrest tensioned within molded polymer frames. Its overall dimensions are 650 by 650 by 1260 mm, with a 680 mm back support height coverage and a 240 mm lumbar support zone. The seat uses fabric-upholstered, high-resilience foam over a molded plywood or polymer seat pan. The finished cushion is 90 mm thick and uses 45 kg per cubic meter foam, while backrest padding thickness is 70 mm. Black molded polymer T-arms provide a clear width of 540 mm between armrests and use padded or polymer contact surfaces. A black glass-filled nylon five-star base, black twin-wheel casters with steel fork axles, and a chromed steel gas lift with a black outer shroud complete the construction. Functional adjustment supports a range of seated tasks. A right-side lever controls pneumatic seat height through a 100 mm stroke using the 50 mm gas lift, giving a seat height range suitable for 760 mm office surfaces. The chair rotates 360 degrees around the central gas-lift axis. Its center-rate tilt mechanism reclines to 15 degrees and includes tension control and lockout. The headrest adjusts 80 mm in height and tilts through 20 degrees, helping support the head and neck during reclined or upright working postures. The chair is rated for a recommended user weight capacity of 136 kg and is intended for users from 160 to 190 cm tall. This model is appropriate for individual workstations and computer desks, as well as private offices, hot desks, administrative zones and other shared workspaces where head, lumbar and arm support are required. Its neutral black finish also allows coordinated use in residential study areas or home offices. 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 carton dimensions of 850 by 420 by 720 mm. The reference carton volume is 0.26 cubic meters per set, and reference assembly time is 40 minutes. At 85 percent space utilization, the indicative 20GP loading is 135 sets. Buyers should also review the fixed armrest layout, adjustment features and user fit range against the intended workspace and occupant requirements before specification.
