Product Description

This mid-back mesh office task chair, model MB-TASK-LGF-BS-01, features a clean, functional visual profile defined by its light gray integrated PP/nylon frame, dark gray tensioned mesh backrest, and contrasting blue woven fabric seat, supported by a polished chrome-plated steel five-star base fitted with black dual-wheel casters. Fixed integrated loop armrests sit at a set height, creating an uncluttered, streamlined silhouette aligned with standard commercial office furniture aesthetics. Constructed for reliable daily use, the chair’s backrest uses stretched breathable polyester mesh to support air circulation during long periods of seated work, paired with a 70mm thick padded lumbar support zone spanning 240mm in height to cradle the lower back. The seat features a 90mm thick high-density cut polyurethane foam core with a 45 kg/m³ density and 55% rebound rate, upholstered in woven blue polyester fabric rated for 30000 Martindale abrasion cycles for long-term wear resistance. Under the foam, a 12mm molded plywood plate provides stable weight distribution, attached to a 2mm thick steel plate tilt chassis and chrome-finished Class 3 pneumatic gas lift. The fixed armrests are formed as a single molded PP/nylon unit, while the five-star base uses polished tubular chrome steel, and dual-wheel PU/nylon composite casters deliver smooth movement across hard and soft floor surfaces. The chair supports full 360-degree swivel rotation via its central bearing and gas lift, with 100mm of vertical seat height adjustment controlled by a right-side under-seat lever. Its synchro-tilt mechanism allows a maximum 125° backward recline, with an adjustable tension knob to modify resistance for different user weights, plus a lock to hold the backrest in the upright working position. The fixed armrests offer consistent arm support at a set height, and the 540mm clear width between armrests accommodates a broad range of user body types. With a maximum recommended static user load of 120 kg, it is rated to support users up to 180cm in height. This chair is well suited for open-plan office workstations for administrative and clerical staff completing 8-hour daily seated shifts, compact home office study spaces for remote work, conference and meeting rooms for short to medium duration gatherings, training rooms and classrooms for rotating temporary seating, and high-traffic call center or shared desk environments where durable multi-user seating is required. It pairs well with a 2.4m executive desk for coordinated workspace setups. For procurement planning, note the chair ships as one set across two cartons, with a 40-minute assembly time per unit, packaged gross weight of 23 kg per set, and 0.26 m³ carton volume allowing 135 sets to be loaded in a 20GP container at 85% space utilization. The unbranded product carries no proprietary labeling, allowing flexible integration into existing standardized furniture fleets without conflicting with established workspace branding schemes.
