Product Description

The Black Mesh Ergonomic Task Chair with Adjustable Arms and Swivel Base is an unbranded mid-back office chair, model MTS-MESH-AR-5P-BLK, designed for everyday task seating. Its appearance is clean and functional: black flexible mesh forms both the back and seat, set within a black molded polymer frame and coordinated with black arm supports, a five-star base, casters, and a visible chrome-finish gas cylinder accented by a black telescopic shroud. The chair has a compact upright silhouette, with a 240 mm lumbar support zone, padded arm pads, and a five-leg base that gives the design a familiar commercial workstation profile. The clear width between the armrests is 540 mm, and overall dimensions are 660 x 660 x 1070 mm. Construction combines breathable mesh, molded components, and steel support elements. The backrest uses tensioned black mesh within a polymer frame and includes an integrated lumbar pad. The seat uses black mesh upholstery over a 60 mm molded foam cushion supported by a polymer load-bearing seat pan; finished seat cushion thickness is 90 mm, backrest padding thickness is 70 mm, and seat foam density is 45 kg/m3 with 40 percent rebound. Rigid polymer T-shaped arms carry soft-touch padded caps, while the height and tilt structure uses a Class 4 chrome-finish steel gas lift, black steel tilt plate, black molded nylon five-star base, and black nylon twin-wheel casters with steel mounting stems. The chair is rated for a recommended user weight of 135 kg, with a static base load rating of 500 kg, and the mesh meets a 50,000-cycle abrasion acceptance criterion. Practical functions support varied desk work. A pneumatic lever provides 100 mm of seat-height adjustment and locks the seat at the chosen position. The synchronized back recline moves through 12 degrees and is regulated by an under-seat tension control knob. Swivel movement allows users to turn between desk areas, while the five twin-wheel casters enable rolling on hard floors or low-pile carpet. These features make the chair suitable for individual desks, open-plan workstations, hot-desks, conference rooms, home studies, and shared computer work areas intended for full-day task seating. Procurement planners should note the chair is supplied as one set in two cartons, with reference assembly time of 40 minutes per set. Packaged reference weight is 23 kg per set, with carton dimensions of 850 by 420 by 720 mm and total reference carton volume of 0.26 cubic meter per set. The specification identifies the arms through padded arm components; buyers should confirm adjustment details against intended desk heights and user needs. The neutral black finish and mesh construction make it a practical choice for offices, educational or shared workspaces, and residential studies where breathable seating and straightforward mobility are priorities.
