Its breathable woven mesh back is stretched over a molded polymer frame, with a visible lumbar contour and a padded central support pad. A curved headrest crowns the backrest, while the black outer frame and reinforced rear spine give the chair a structured executive appearance. The seat uses black mesh over a molded cushion carrier with a contoured waterfall front, and the matching black armrests, five-star base, casters, and sliding footrest maintain a coordinated visual layout suitable for professional interiors. Construction combines flexible support surfaces with durable load-bearing components. The seat contains a molded polyurethane foam insert, with 90 millimeters of finished cushion thickness and a 60-millimeter effective comfort layer at the rear pressure zone. Backrest padding is 70 millimeters thick, and the lumbar support zone is 240 millimeters high. The frame is injection-molded black polymer, while the base is black steel in a five-star form. Twin-wheel casters provide mobility, and the gas lift offers 80 millimeters of vertical travel. The chair weighs 18.5 kilograms, supports a maximum user weight of 150 kilograms, and carries a 200-kilogram static load rating for the seat.
