Product Description

The UMB-MT-GRY-01 is an unbranded mid-back mesh swivel task chair designed for practical daily office seating. Its coordinated gray appearance combines a molded polymer back frame, mesh back and seat surfaces, and fixed armrests with dark gray soft-touch top pads. The chair has a measured footprint of 650 mm wide by 620 mm deep and an overall height of 1080 mm. A five-star black nylon base, twin-wheel casters, and central gas-lift column give the chair a familiar task-chair silhouette, while the open Y-frame and structural ribs keep the back visually light. Clear spacing between the armrests is 540 mm, providing defined shoulder and arm room at the seat. Construction uses a gray glass-fiber-reinforced nylon or polypropylene back frame, gray woven mesh suspension, and a seat surface of gray mesh or mesh-textured fabric over a padded seat plate. The seat includes a molded polyurethane foam cushion with a 90 mm finished thickness, 60 mm published foam thickness, and 35 kg/m3 density target, with a stated comfort grade of 35 percent ball rebound. Backrest padding thickness is 70 mm, and the lumbar support zone is 240 mm high. Under the seat are a black powder-coated steel gas-lift column and steel tilt mechanism. The gas lift has a Class 4 target, and the recommended user weight capacity is 120 kg. Static-load targets are 136 kg for the mesh back and 1136 kg for the base. The net chair weight is 13.5 kg. Functionality centers on adjustable and mobile work positioning. A visible right-side lever operates pneumatic seat-height adjustment with a 100 mm target stroke. The center-tilt mechanism provides 110 degrees of back travel with a single-position lock target, while a rear rotary knob controls tilt tension to match recline resistance to user weight and preference. The seat rotates 360 degrees around the center column, and twin-wheel casters support rolling access around a workstation. Fixed armrests offer consistent upper-body support without added adjustment complexity. The chair is suited to open-office workstations at 760 mm high desks, where swivel movement, height adjustment, and rolling mobility support routine computer tasks. Its scale also fits home studies, shared workrooms, hoteling stations, and individual or shared administrative desks. Procurement planning should note that each set ships in two cartons, with packaged gross weight of 23 kg and carton volume of 0.26 cubic meter per set. Reference carton dimensions are 850 by 420 by 720 mm, reference assembly time is 40 minutes per set, and indicative loading is 135 sets in a 20GP container at 85 percent space utilization. These details make the model appropriate for buyers seeking a uniform gray mesh task chair for general workplace, study, or shared seating programs.
