Product Description

The Mesh-Back Swivel Task Chair with Fixed Armrests, model MB-T500-GRY, is an unbranded office task chair designed for practical daily seating in commercial and residential work settings. Its appearance combines a gray flexible mesh backrest with a gray fabric-upholstered padded seat, contrasted by a black molded back frame, black fixed polymer armrests, and a black five-star caster base. The mid-height back uses contoured side rails and a defined lumbar support zone, giving the chair a structured, functional profile suited to shared workspaces. The compact 620 by 620 millimeter footprint and 1010 millimeter overall height support orderly placement at workstations or meeting tables. Construction balances comfort, support, and mobility. The backrest consists of gray mesh held in a black injection-molded polypropylene frame, while the seat uses molded foam over a 12 millimeter molded plywood or composite load-bearing pan. The finished cushion is 90 millimeters thick, uses 35 kilogram per cubic meter foam, and is covered with 1.2 millimeter gray fabric. The armrests are fixed black polymer T-arms bolted beneath the seat, with rounded pads and a clear width of 540 millimeters between them. A powder-coated steel gas lift, steel tilt plate, nylon five-star base, and polyurethane twin-wheel casters complete the durable, service-oriented specification. Operation is straightforward for multi-user environments. The seat provides 360-degree continuous swivel and pneumatic height adjustment from 440 to 540 millimeters through a side lever. The synchronized seat-and-back tilt offers an upright 90-degree working position, a 14-degree rear recline, one tilt lock at the upright angle, and knob-controlled tension for users within the 120 kilogram recommended weight capacity. Fixed armrests provide consistent support without adjustment complexity, while five twin-wheel casters allow omnidirectional movement on hard floors and low-pile carpet. This chair is well suited to open-plan workstations, hot-desking areas, meeting and training rooms, reception or administrative counters, and home offices used for daily computer work. It pairs effectively with standard office desks and a 700 millimeter deep desk setup accommodating a monitor, keyboard, and task light. Procurement teams should note that the chair is supplied as one set across two cartons, with packaged gross weight listed at 23 kilograms and a reference assembly time of 40 minutes per set. The fixed arms and compact form are beneficial where uniformity, easy repositioning, and space efficiency matter, but the chair is not intended where adjustable arm geometry is required. Product planning should also account for floor type, desk height, shared-user turnover, and maintenance access in high-use commercial interiors.
