The High-Back Black Leather Executive Swivel Chair is a formal single-person executive office chair with a tall, structured silhouette and a coordinated black-and-polished-metal finish. Its leather-faced upholstery shows natural creases and is finished with piped perimeter detailing, while the back uses vertical channel wrinkling to create a traditional managerial appearance. An integrated rounded head cushion, contoured lower-back padding, and fixed loop arms give the chair a balanced, symmetrical layout suited to desk-facing work, meetings, and reception settings. Overall dimensions are 680 by 720 by 1220 millimeters, with a 540-millimeter clear width between the armrests. The seat cushion uses molded high-resilience polyurethane foam with a 90-millimeter thickness target, and the back combines dual-density polyurethane padding with a 70-millimeter padding thickness and a 240-millimeter lumbar support zone. Internal construction includes a plywood or molded composite seat carrier, a steel-reinforced plywood or tubular steel back frame, and black powder-coated bent steel or die-cast aluminum arm supports with leather-padded tops. The polished die-cast aluminum five-prong base has a chrome mirror finish and supports a chrome-plated steel Class 4 gas lift. Five twin-wheel casters provide omnidirectional mobility. Functional features include pneumatic height adjustment through an 80-millimeter stroke using the right-side lever, 360-degree continuous swivel, synchronized seat-and-back recline with an 18-degree rearward tilt target, multi-position tilt lock, and a rotary tension control for backward resistance. The fixed padded arms are positioned to support forearms during keyboard work or meetings, while the passive curved lumbar padding provides lower-back contouring without a separate adjustable paddle. The chair has a net weight of 22 kilograms and a rated user weight of 150 kilograms. It is appropriate for private executive offices, manager workstations, boardrooms, senior reception or guest areas, and dedicated home offices with hard flooring or low-pile carpet. For residential placement, the desk should provide sufficient depth; in commercial settings, the formal finish pairs naturally with executive desks and conference furniture. Procurement teams should confirm arm color, leather grade, caster type, and fire-retardant foam before bulk purchase. Each set is supplied in two cartons, with a packaged gross weight of 23 kilograms and a reference assembly time of 40 minutes per set.
