Product Description

The Black Mesh High-Back Ergonomic Office Chair with Headrest, model EM-HB-MESH-01, is an unbranded seating solution designed for task-focused work environments. Its upright, high-back silhouette combines a black flexible mesh back panel and matching mesh headrest with a black upholstered foam seat. Molded armrests flank the seat, while the five-star base and twin-wheel casters create a familiar swivel-chair profile suited to organized workstation layouts. Overall dimensions are 650 x 680 x 1290 mm, with 540 mm of clear width between the armrests. The 90 mm finished seat cushion and 70 mm backrest padding provide a substantial visual form, and the 240 mm lumbar support zone is positioned to encourage contact through the lower back. Construction balances breathable and molded components. The backrest uses black mesh webbing over a molded polypropylene outer frame with a 2.0 mm wall target. The seat features molded polyurethane foam at a 45 kg/m3 density target, covered in black woven fabric, with an 8 mm molded polypropylene seat pan and steel reinforcing plate beneath. A steel mechanism supports the control functions, and the nylon five-star base carries twin-wheel casters. The chair has a published net weight of 19.5 kg and a recommended user weight capacity of 136 kg. Its static seat load verification target is 680 kg, while caster rolling, gas lift cycling, and backrest recline are each specified to 100000 cycles; seat slide endurance is rated to 20000 cycles. Practical adjustment supports extended seated work. A right-side under-seat lever controls pneumatic seat height through a 90 mm stroke. The synchro-tilt mechanism allows the backrest to recline 15 degrees, from 90 to 105 degrees from vertical, and a rear rotary knob provides tension adjustment across four user-weight settings. The headrest moves through 80 mm of vertical travel and pivots 15 degrees, helping users who want head support in addition to lumbar contact and swivel mobility. The chair is appropriate for open-plan offices, workstation clusters, and home offices where all-day seated tasks require a breathable back. Its recommended user profile covers people from 1600 to 1900 mm tall. Procurement planning should account for fixed arms, a black mesh aesthetic, self-contained swivel mobility, and assembly requirements. Each set is supplied in two cartons, with a reference packaged gross weight of 23 kg and reference carton dimensions of 850 x 420 x 720 mm. The reference carton volume is 0.26 m3 per set, and reference assembly time is 40 minutes per set.
