Product Description

The Black Mesh Mid-Back Swivel Task Chair with Blue Seat and Fixed Arms presents a clean commercial office silhouette with a contrasting black-and-blue finish. Its black flexible woven mesh back is tensioned within a polymer outer frame and shaped by molded side and lumbar borders, while the blue woven polyester seat adds a distinct color accent. Fixed black T-armrests, a five-star mobile base, and twin-wheel casters complete the structured task-chair layout. The mid-back form includes a contoured lower mesh zone for flexible lumbar contact without a separate adjustable pillow. Construction combines steel, polypropylene, nylon, foam, and upholstered fabric. The seat uses a 90 mm finished cushion over a 70 mm molded or cut polyurethane foam core at 45 kg/m3 density, supported by an 8 mm polypropylene load-bearing seat pan with a steel mounting plate. Armrests feature soft-touch polyurethane pads on rigid supports fixed to the seat mechanism with black-painted rectangular steel posts. The under-seat assembly uses a black powder-coated steel synchro-tilt plate and a 50 mm outer-diameter black class-4 steel gas lift. The back panel is designed with five-point load-distributing elastic mesh zones, and the blue seat fabric is specified to a 50,000 Martindale abrasion acceptance target. Functional features support everyday desk work. The chair rotates a full 360 degrees, and the under-seat lever provides 100 mm of pneumatic height adjustment. A synchronous seat-and-back tilt offers a 15 degree maximum recline, with a rotary knob for backward resistance and a one-position upright lock for focused keyboard tasks. Fixed armrests provide consistent forearm support, while nylon twin-wheel casters support movement around a workstation. The recommended user weight capacity is 120 kg, and the chair is intended for users from 155 to 185 cm in stature. This unbranded model is suited to open-plan office workstations, home offices, studies, meeting rooms, shared desks, administrative areas, reception spaces, and hot-desking environments. Its neutral black structure works in commercial interiors, while the blue seat supports color coordination. Overall dimensions are 620 x 600 x 1010 mm, with 540 mm of clear width between armrests. For procurement, confirm that standard casters are appropriate for the installation; hard-floor caster treads should be specified where wood, tile, or vinyl floors require protection. Each chair is supplied as one set across two cartons, with a packaged gross weight of 23 kg per set and a reference assembly time of 40 minutes. The model number is MB-MESH-BLUE-TASK-01.
