Product Description

The Black Mesh Ergonomic Task Chair with Fixed Arms and Five-Star Base is an unbranded office chair suited to daily desk-based work. Model TSK-MSH-FA-01 presents a streamlined black appearance, with a flexible woven mesh back set within a molded perimeter frame. Its contoured backrest includes a defined lumbar support zone, while the fabric-covered foam seat gives the chair a conventional task-chair silhouette. Fixed T-shaped arms frame the seat, and the five-star base, central gas lift, and twin-wheel casters complete the familiar commercial seating layout. Construction combines molded plastic, steel, foam, fabric, and nylon components. The back frame and arm supports use an injection-molded black polypropylene or nylon structure with rigid T-arm posts. Armrest pads are flat rectangular contact surfaces in black polyurethane or molded plastic. The seat cushion uses high-resilience polyurethane foam covered in black woven fabric, with a finished cushion thickness of 90 mm, while backrest padding is 70 mm thick and the lumbar support zone is 240 mm high. Overall dimensions are 630 x 650 x 1050 mm, with 540 mm of clear width between the armrests. Functional features support regular workstation movement. A pneumatic center lift provides 100 mm of seat-height travel through an under-seat lever, and the seat and back rotate 360 degrees on the central gas-lift swivel bearing. The synchro-style recline offers rearward travel up to 19 degrees, adjusted with a side tension knob. A black powder-coated steel tilt mechanism includes a visible side pivot, while the painted steel five-star base carries five dual-wheel nylon casters for rolling mobility on hard flooring. Fixed armrests provide stable upper-body support without adjustable-width or height-adjustment complexity. The chair is appropriate for open-plan office workstations, computer desks, hot desks, administrative and clerical stations, meeting support areas, and home offices where a compact black commercial task chair is preferred. Its mesh back contributes a lighter visual presence than fully upholstered executive seating, while the all-black finish coordinates with neutral office interiors. Procurement teams should note that each set ships in two cartons, with packaged gross weight of 23 kg and reference carton volume of 0.26 cubic meters. The reference assembly time is 40 minutes per set. Rated use supports a recommended user weight of 136 kg, and the published durability targets include 100000 gas-lift, caster, seat-impact cycles and 120000 backrest cyclic-load cycles. These details make the chair best considered as a practical standard task seat for routine office and residential workspace use rather than a bespoke executive or heavy-specialty seating solution.
