The Black Upholstered Swivel Executive Chair with Integrated Armrests presents a structured high-back silhouette in a coordinated black finish, designed for professional desk settings where support and a formal appearance are equally important. Smooth leather-look upholstery covers the contoured seat and back, with perimeter stitching on the seat and a horizontal lumbar seam defining the backrest. Padded armrests are integrated into the chair body, capped in the same black upholstery and shaped to provide continuous forearm and side support. A chrome-plated five-star base, polished metal gas lift, and black twin-wheel casters create a visual contrast between the black upper body and bright metal lower frame. Overall dimensions are 650 by 680 by 1080 millimetres, with 540 millimetres of clear width between the armrests. Construction combines cushioned surfaces with a supportive internal structure. The seat uses a 90 millimetre, 45 kg/m3 molded polyurethane cushion over a 12 millimetre plywood or equivalent molded composite shell. Back support is provided by a contoured 50 millimetre molded pad, a 240 millimetre lumbar support zone, and a 20 by 1.5 millimetre tubular steel inner frame. The multi-lever tilt seat plate is black powder-coated steel, while height adjustment is handled by a 50 millimetre chrome-plated steel pneumatic cylinder. The chair weighs 18 kilograms and carries a recommended user weight capacity of 150 kilograms. Performance targets include 100,000 caster rolling cycles and 100,000 gas-lift height-adjustment cycles. Functional controls support extended desk work. A pneumatic lever provides 90 millimetres of height travel, adjusting the seat from 450 to 540 millimetres. The chair rotates 360 degrees around the central gas-lift axis, and the backrest reclines to 115 degrees with user-weight tension balancing. Angles can be locked at 90, 102, and 115 degrees, while a rear rotary knob adjusts recline resistance. An under-seat paddle controls a 50 millimetre seat-depth slide. Fixed armrests sit 230 millimetres above the seat. The model is suited to executive offices, private workstations, meeting rooms, reception or consultation spaces, and home offices on hard floors or low-pile carpet. It works with a 1400 millimetre wide executive desk and conference tables 720 to 760 millimetres high. Desks should provide at least 700 millimetres of under-table knee depth and 650 millimetres of chair clearance. Procurement planning should account for unbranded supply, assembly time of 40 minutes per set, shipment as one set across two cartons, and a packaged gross weight of 23 kilograms per set, with reference carton volume of 0.26 cubic metres.
