The High-Back Black Leather Executive Swivel Office Chair offers a formal seating solution for executive, administrative, and home-office settings. Its tall upholstered back, black finish, fixed padded armrests, and polished aluminum five-star base create a structured professional appearance suited to private offices, conference rooms, reception workstations, and dedicated residential studies. Visually, the chair features a black full-grain-style leather-look surface with a stitched seat perimeter. The backrest is a black upholstered panel with a horizontal lumbar seam, raised side bolsters, and a recessed central area that forms an integrated curved lumbar zone. The armrests use matching black padded upholstery, with curved support faces, vertical side panels, and rigid supports connected to the seat frame. Beneath the seat, a polished die-cast aluminum base with curved open spokes supports chrome-plated steel gas-lift components, while dual-wheel casters complete the executive aesthetic. Construction combines padded comfort with a supportive internal structure. The seat uses a molded polyurethane foam pad with a rounded waterfall front, and the back cushion uses contoured polyurethane foam over a rigid load-bearing frame. The finished seat cushion is 90 mm thick, while backrest padding is 70 mm thick. The black powder-coated steel tilt mechanism is operated by two side levers, and the chrome-plated telescopic gas lift includes a black plastic shroud. The recommended user weight capacity is 150 kg. The chair supports 360-degree swivel movement and pneumatic seat-height adjustment with an 80 mm stroke. Its synchronized seat-and-back tilt provides 15 degrees of rearward travel, tension control, and locks in both upright and reclined positions. Five dual-wheel casters allow omnidirectional movement across carpet, tile, or wood floors. The fixed armrests provide continuous forearm support but do not adjust in height, width, or pivot angle. This model is appropriate for managers and directors in private offices, open-plan workstations with standard office desks, short collaborative meetings, reception staff requiring extended seating, and home studies. Procurement planning should account for a two-carton set, assembly time of 40 minutes per set, and packaged gross weight of 23 kg per set. When pairing the chair with a desk, allow sufficient under-surface clearance and consider a suitable floor mat for the selected flooring.
