Product Description

The Black Mesh Ergonomic Task Chair with Fixed Arms is an unbranded office seating solution designed for everyday desk-based work. Its visual profile combines a black breathable mesh back, a black fabric-upholstered seat, fixed T-shaped arms, and a five-star rolling base. The contoured polymer outer frame gives the backrest a structured appearance, while the chromed steel gas cylinder and black powder-coated steel tilt plate provide a functional contrast beneath the seat. The chair measures 635 millimeters wide, 640 millimeters deep, and 1010 millimeters high, with a 540-millimeter clear width between the armrests. Construction centers on a black elastic mesh backrest for airflow and a molded polyurethane foam seat covered in black woven fabric. The finished cushion is 90 millimeters thick, uses 45 kilograms per cubic meter foam, and rests on a 12-millimeter molded plywood or polymer load-bearing shell. Backrest padding is 70 millimeters thick, and the lumbar support zone is 240 millimeters high. Fixed polymer armrests include padded flat contact surfaces, while the polymer five-star base carries five 60-millimeter twin-wheel casters. A chromed telescopic steel gas lift with a black outer collar connects the seat to the base. Practical operation is handled by a right-side lever for pneumatic height adjustment, offering 90 millimeters of vertical travel. The synchronized seat-and-back tilt reaches 108 degrees and includes a single-position tilt lock. A visible side or underside rotary knob adjusts backward recline resistance, and the 360-degree swivel seat supports easy movement between work areas. Durability targets include a recommended user weight capacity of 120 kilograms, 120,000 backrest dynamic tilt cycles, 100,000 gas-lift height adjustment cycles, and 100,000 caster rolling cycles. The chair is suited to open-plan office workstations at desk heights of 530 millimeters and below within the stated range, as well as meeting spaces, computer work areas, training rooms, shared desks, and home offices. Its compact 635-millimeter footprint and fixed arms make it appropriate for planned rows or shared bench layouts where consistent arm positioning is preferred. Procurement planning should note that each set is supplied unbranded under model TASK-MESH-FA-BK-01 and ships in two cartons. Reference packaged weight is 23 kilograms per set, carton volume is 0.26 cubic meters per set, and reference assembly time is 40 minutes per set. The chair is intended for use with hard-floor casters as specified, so buyers should assess floor type, workstation height, assembly resources, and bulk delivery handling before purchase.
