Product Description

The Black Mesh Ergonomic Task Chair with Mid Back and Fixed Arms, model ETC-MESH-BK-01, offers a functional, understated seating solution for daily office use. Its matte black engineered-polymer frame, woven mesh surfaces, and nylon five-star base create a clean commercial appearance suited to neutral or contemporary interiors. The mid-height backrest uses black woven flexible mesh over an injection-molded polymer frame, with Y-shaped lumbar reinforcement and a 240 mm lumbar support zone. The seat combines a black woven mesh surface with a contoured polymer seat pan and elastic edge support. Fixed T-shaped arms and matching side supports preserve a simple silhouette while defining the seating area. The overall footprint is 640 x 620 x 1020 mm, with 540 mm of clear width between armrests. Cushioning measures 90 mm on the seat and 70 mm on the backrest. Construction balances molded components with metal support. A 2.5 mm stamped steel mechanism plate with a black powder-coated finish sits within the control structure, while the 50 mm steel gas-lift cylinder includes a black telescoping plastic shroud and chrome upper collar. The matte black, glass-filled nylon five-star base has a 330 mm radius and carries five dual-wheel casters. The chair has a net weight of 13.8 kg and a recommended user weight capacity of 136 kg. Validation targets include a 680 kg static seat load, 136 kg rearward load on the back frame, 100,000 caster rolling cycles, and 100,000 gas-lift height-adjustment cycles. Practical adjustment supports standard desk tasks. The right-side lever controls pneumatic seat-height adjustment with 100 mm of travel, giving a seat-height range of 430 to 530 mm. A synchronized seat-and-back tilt provides 15 degrees of rearward travel, and a tension knob allows resistance adjustment. The chair also rotates 360 degrees around the central gas-lift axis and rolls on hard floors or low-pile carpet; no brakes are visible. It is recommended for users from 160 to 188 cm tall. The chair fits office workstations with desks 720 to 760 mm high, as well as open-plan offices, home offices, task areas, meeting spaces, and hot-desk environments that call for compact rolling seating. Procurement teams should note the unbranded supply format, shipment as one set in two cartons, 40-minute reference assembly time, 23 kg packaged gross weight, and 0.26 cubic meter carton volume. The reference carton dimensions are 850 x 420 x 720 mm, and indicative loading is 135 sets in a 20GP container at 85 percent space utilization.
