Product Description

The Mid-Back Mesh Swivel Task Chair with Fixed Arms is an unbranded office chair designed for practical daily desk use. Its structured, commercial-task appearance combines a grey flexible mesh back set within a black moulded plastic outer frame, a black upholstered foam seat, fixed black polymer T-arms, and a black five-star base. The overall form is compact and balanced, with radial caster supports and a raised center hub giving the chair a conventional workstation profile suited to orderly open-plan or residential office layouts. Construction centers on a load-bearing seat shell with cut foam and a black fabric or bonded-leather look upholstery finish. The seat foam is specified at 70 millimeters thick with 45 kilograms per cubic meter density and 40 percent rebound, while the finished cushion thickness is 90 millimeters. The backrest includes 70 millimeters of padding thickness and a 240-millimeter lumbar support zone. Fixed armrests use horizontal pads and vertical supports, with 540 millimeters of clear width between them. Mobility is supported by five twin-wheel casters, a black moulded nylon or glass-filled nylon base, and a black powder-coated steel gas cylinder. A steel or polymer tilt mechanism is located beneath the seat. Functionally, the chair provides 360-degree swivel around the gas-lift centerline and pneumatic seat-height adjustment through a visible right-side lever with 100 millimeters of travel. Its spring-tension synchro or center-tilt mechanism allows 12 degrees of rearward recline and includes one lock position. The dual-wheel casters are intended for omnidirectional movement on hard floors or low-pile carpet. The recommended user weight capacity is 120 kilograms, and the chair is designed for general adults performing six hours of daily computer or desk tasks. This model is suitable for open-plan offices, home offices, and shared workstations where swivel access and a compact 620-millimeter footprint are priorities. Procurement teams should note that it is supplied as one set in two cartons, with a packaged gross weight of 23 kilograms and a reference assembly time of 40 minutes per set. Buyers should also confirm the preferred seat upholstery option, base material specification, caster suitability for the intended floor surface, and replacement or warranty arrangements before purchase.
