Product Description

The Black Mesh Ergonomic Task Chair with Fixed Armrests is a high-back office seating solution with a streamlined, professional appearance. Its black mesh surfaces, molded seat structure, fixed T-shaped armrests, and five-star base create a consistent visual profile suited to practical workstation environments. The backrest uses flexible woven mesh over a framed Y-shaped lumbar support, while the contoured seat presents a black woven mesh surface above a molded cushion carrier. A rounded polymer frame outlines the back, and the armrests connect directly to the seat support for a clean, structured layout. Overall dimensions are 640 x 620 x 1040 mm, with 540 mm of clear width between the armrests. Construction combines breathable upholstery with durable support components. The seat includes a 90 mm finished cushion thickness and a molded elastic support layer with a 45 kg/m3 equivalent support specification. The backrest has 70 mm of padding thickness and a lumbar support zone height of 240 mm. The frame and fixed armrests are made from black nylon or polymer materials, while the central height mechanism uses a black-coated steel gas lift with a polymer telescopic sleeve and chrome release collar. The chair rests on a black molded nylon five-star base with reinforced spokes and twin-wheel casters. It has a net weight of 14.5 kg and is intended for users up to 120 kg. Functional controls support varied working postures. A visible side lever operates pneumatic seat-height adjustment through a 100 mm stroke. The synchronized tilt mechanism allows 20 degrees of back recline with proportional seat movement, and a rear rotary knob adjusts backward resistance to suit user weight and recline preference. The gas-lift turntable and caster base provide 360-degree swivel movement, making the chair easy to reposition around a desk. Durability targets include 120,000 backrest cycles, 100,000 caster rolling cycles, and 100,000 gas-lift height-adjustment cycles. This model is appropriate for open-plan offices, home offices, administrative workstations, hot desks, meeting rooms, and training areas. Its breathable back and adjustable support make it suitable for shared desks used by multiple adults. Procurement teams should plan for one set packed across two cartons, a packaged gross weight of 23 kg, a reference carton volume of 0.26 cubic meters, and a reference assembly time of 40 minutes per set.
