产品描述

The Black Mesh Swivel Task Chair with Fixed T-Arms, model MB-TASK-50B, is an unbranded office chair designed for practical daily seating in commercial and home work environments. Its coordinated black finish gives it a clean, functional appearance that integrates readily with neutral desk systems, open-plan offices, and residential study furniture. The chair presents a rectangular mesh back set within a molded polymer frame, paired with a generously upholstered seat, fixed T-shaped armrests, and a five-star caster base. The clear width between armrests provides defined seating space, while the central gas lift and rolling base establish the familiar compact footprint of a modern task chair. Construction balances breathable support with cushioned comfort. The backrest uses flexible black woven mesh tensioned in a molded polymer frame, with an integrated lumbar bridge and a dedicated lumbar support zone. The seat combines black woven fabric over molded polyurethane foam; the cushion includes a 60 mm molded foam component within a finished cushion thickness of 90 mm. A molded plywood or reinforced polymer carrier sits beneath the cushion, and the armrests use polymer support posts with flat fixed pads. The base is formed from nylon and fitted with twin-wheel casters, while height adjustment relies on a steel gas lift. The chair supports one user and is rated for a recommended user weight of 136 kg. A right-side lever operates pneumatic seat-height adjustment through a 100 mm stroke. The synchro-tilt mechanism allows the seat and back to move together, with a 15-degree seat tilt and 22-degree back tilt, and can be locked in the upright position. A rotary tension knob beneath the seat adjusts tilt resistance. Full 360-degree swivel and smooth-rolling casters support movement between desk tasks and nearby work surfaces. This model is appropriate for individual desk workstations, shared desks, conference rooms, training rooms, home studies, computer seating, and temporary work points in 8-hour office settings. Buyers should plan for assembly: each set ships in two cartons, with a reference assembly time of 40 minutes. Procurement teams should also account for packaged gross weight and carton volume when arranging delivery, storage, and multi-unit projects. Fixed T-arms aid arm support and visual consistency, but should be checked for compatibility with desk height and clearance before specification.
