Product Description

The Black Mesh Swivel Task Chair with Fixed T-Arms and Lumbar Pad is an unbranded office seating solution, model MB-TASK-502-BLK, designed for practical daily use in workstation and shared task settings. Its streamlined black appearance combines a woven polyester mesh back with a molded polymer frame, a fabric-upholstered foam seat, black T-shaped arms, and a five-star caster base for a coordinated professional look. The open mesh back gives the chair a lighter visual profile while the padded lumbar component creates a defined support zone at the lower back. Fixed armrests provide a consistent boundary and rectangular contact pads, while the central gas-lift column and star base establish a familiar task-chair layout. Overall dimensions are 620 x 630 x 1010 mm, with 540 mm of clear width between the armrests. Construction uses a black woven polyester mesh panel held in an injection-molded polymer outer frame with an integrated lower lumbar bridge. The seat features a cut polyurethane foam cushion at 90 mm finished thickness, upholstered in black woven fabric over a rigid seat pan. Backrest padding thickness is 70 mm, and the padded black polymer lumbar cushion is mounted on an adjustable central bracket within a 240 mm support-zone height. The fixed T-arms use molded polymer vertical supports and contact pads. Mobility and height structure are provided by a black nylon five-star base, twin-wheel casters, and a chrome-finished steel gas-lift column. Functionality centers on flexible task movement. A visible under-seat lever operates pneumatic seat-height adjustment with a 100 mm target travel, and the chair rotates through a 360-degree swivel around the central bearing. A synchro-style tilt mechanism with a visible right-side lever offers a 12-degree target rear recline, while an under-seat rotary tension knob controls recline resistance. The suggested user weight capacity is 120 kg. Product verification targets include 35 kg/m3 seat foam density, a 120 N back mesh tensile target, 950 N seat static-load target, 120,000 back-rest cyclic durability cycles, and 100,000 caster rolling durability cycles. The chair is suited to individual desks in open-plan offices, home offices, and administrative workstations where swivel access, caster mobility, and height adjustment are needed. It is also appropriate for hot desks, meeting rooms, and shared work areas requiring a compact black mesh chair with fixed arms and basic lumbar support. For procurement, allow for assembly and receiving planning: the product is supplied as one set in two cartons, with a 40-minute reference assembly time per set. Reference carton dimensions are 850 x 420 x 720 mm, packaged gross weight is 23 kg per set, and reference carton volume is 0.26 cubic meters per set. Net weight is 12.5 kg and gross weight is 14 kg. Buyers should also confirm fixed-arm clearance, seat-height range, lumbar adjustability, and caster suitability for the intended floor surface before placement.
