Product Description

The Black Mesh Ergonomic Task Chair with Height-Adjustable Arms is an unbranded office seating solution, model EMC-MESH-ARMB-01, designed for sustained workstation use. Its coordinated black appearance uses a flexible mesh backrest stretched over a black polymer outer frame, while the contoured seat presents a black mesh or mesh-fabric surface over a molded polymer seat pan. A padded black lumbar band is integrated into the lower backrest, and matching black polymer armrest pads and posts create a clean, consistent profile. The chair measures 650 by 650 by 1120 mm overall, with a 540 mm clear width between the armrests, a 90 mm finished seat cushion, 70 mm of backrest padding, and a 240 mm lumbar support zone height. Its five-star nylon base and twin-wheel polymer casters complete the mobile, task-oriented form. Construction balances breathable support with durable central structure. The backrest uses flexible mesh on a polymer frame, the seat is supported by a molded polymer pan, and the armrests use injection-molded polymer pads and posts with internal height-adjustment slides. A chrome steel inner piston, black telescopic outer sleeve, and polymer control housing form the gas-lift center. The chair is rated for a recommended user weight of 136 kg and has a net weight of 16 kg. Documented durability targets include a 1020 kg static vertical seat-load acceptance target, 150,000 backrest cycles, 100,000 seat-height adjustment cycles, 100,000 caster rolling cycles, and a 57 kg per arm vertical static-load target. Pneumatic seat-height adjustment provides 100 mm of travel through a lever, and the synchronized tilt mechanism offers a 15-degree rear recline with tension control. Arm pads move 60 mm vertically to support shoulder and desk alignment, while the 360-degree swivel seat and five caster-mounted legs allow easy movement around a workstation. These features make the chair suitable for open-plan desks, private offices, home offices, bench desks, meeting rooms, and hot-desk settings where breathable task seating and mobility are needed. Procurement planning should account for delivery as one set in two cartons, with packaged gross weight of 23 kg per set, reference carton dimensions of 850 by 420 by 720 mm, and total carton volume of 0.26 cubic meters per set. Assembly time is referenced at 40 minutes per set, and an indicative 20-foot general-purpose container can hold 135 sets at 85 percent space utilization.
