Product Description

The Ergonomic Gray Mesh Executive Task Chair combines a structured high-back profile with a coordinated gray finish suited to professional work environments. Its tall mesh back, contoured headrest, molded seat, and four-dimensional arm supports create a layered executive appearance, while the five-star base and twin-wheel casters maintain the familiar mobility of a task chair. With an overall footprint of 680 x 690 x 1290 mm and a clear width of 540 mm between armrests, the design balances substantial back support with a practical workstation scale. Gray engineered polymer-fiber mesh with a woven open-cell structure is used on the back and headrest. The seat support uses a gray mesh panel bonded or clamped to a molded load-distributing shell, with a 90 mm finished cushion, an 8 mm molded elastic mesh carrier, and high-resilience foam specified at 40 kg per cubic meter. The backrest has 70 mm of padding and a 240 mm lumbar support zone. Its light gray frame is offered in painted or powder-coated metal with a reinforced polymer back frame, while arm uprights may be polymer or aluminum and pads are molded polyurethane. Buyers can select from a molded reinforced nylon or die-cast aluminum five-star base, both finished in light gray. Functional support is delivered through synchronized seat-and-back recline. The back moves through 120 degrees with linked seat tilt and lockable positions, and a pneumatic lever provides 90 mm of seat-height adjustment. The curved mesh headrest moves 90 mm in height and pivots through 25 degrees, while the independent curved lumbar panel follows the lower back and is set with the visible side knob or bracket. The 4D arms add further personal adjustment, and swivel, gas lift, and black casters support easy movement at the desk. The chair is appropriate for open-plan workstations, private offices, home offices, and computer-task rooms where users need a high-back chair capable of supporting extended desk work. It is specified for users up to 190 cm tall and 150 kg. Design verification targets include a 680 kg static seat load, 120,000 backrest cycles, 100,000 gas-lift operations, and 100,000 caster rolling cycles. Procurement teams should note the unbranded model EM-GRY-HR4D-01, 21 kg net chair weight, two-carton packaging, 23 kg packaged weight, 0.26 cubic meter carton volume, and 40-minute assembly reference. A 40-foot high-cube container accommodates 370 cartons.
