Product Description

The Black Mesh Swivel Task Chair with Fixed T-Armrests is an unbranded office task chair designed for routine desk use in commercial and home settings. It presents a clean, functional profile with a black mesh back, black upholstered seat, black molded frame and fixed T-shaped armrests. Its compact five-star base and twin-wheel casters give it a practical workstation footprint, while the neutral black finish supports coordinated interiors without becoming visually dominant. The backrest uses black woven polyester or nylon mesh tensioned within a rigid molded polymer frame, with a visible frame width of 25 mm. A central black molded polymer lumbar pad provides passive lower-back contact and includes three horizontal ventilation slots. The seat combines a 70 mm thick high-resilience polyurethane cushion over a 12 mm polypropylene load-bearing pan, finished with black woven fabric and a stitched edge panel. The stated finished cushion thickness is 90 mm. Arm support comes from black powder-coated steel or aluminum rectangular posts topped with flat black polyurethane or polypropylene pads. The gas lift features a black steel outer tube, chrome center section and class 4 internal cylinder. Operation is centered around under-seat controls. A right-side lever controls 100 mm of pneumatic seat-height travel, while the single-lever tilt mechanism allows 12 degrees of backward movement and an upright lock position. A rotary tension knob adjusts backward resistance for users up to 130 kg. The seat and back rotate 360 degrees, and five twin-wheel casters support omnidirectional movement on hard floors and low-pile carpet. The fixed armrests place forearm support 230 mm above the seat, with 540 mm of clear width between them, making the chair suited to regular computer, document, laptop and meeting tasks. This model fits open-plan workstations, private offices, meeting rooms, hot-desking areas and reception desks. It is also appropriate for a home office or compact study where its 620 mm base footprint and dark finish are beneficial. Procurement teams should allow for assembly time of 40 minutes per set and plan receiving around a two-carton package with a packaged gross weight of 23 kg per set. Buyers should also confirm desk height, floor type, intended user turnover and preferred armrest style, since the T-armrests and lumbar pad are fixed rather than adjustable.
