This high-back swivel executive office chair features a polished, professional silhouette defined by smooth brown top-grain semi-aniline leather upholstery, curved integrated fixed armrests covered in matching leather, and a contoured high backrest sized to deliver full upper back and head support. Tight, uniform brown bonded nylon stitching runs along all upholstery edges for a refined finish, while a polished die-cast aluminum five-star base paired with black nylon dual-wheel casters creates a balanced, formal visual profile suitable for upscale settings. The chair’s form follows standard executive chair proportions, with a thick padded seat and contoured backrest that align with ergonomic support priorities for extended seating. Construction centers on durable, commercial-grade components. Molded plywood frames form the internal support for the seat and backrest, wrapped in high-resilience polyurethane foam: 45kg/m³ density foam for the 80mm thick seat cushion, and 35kg/m³ density molded foam for the 50mm thick backrest to deliver built-in mid-back lumbar support. The steel adjustment mechanism features a black powder-coated finish, paired with a Class 3 carbon steel chrome-plated gas lift, glass-filled nylon adjustment levers, and casters fitted with soft polyurethane treads. All components are built to support regular heavy use, with abrasion-resistant upholstery, a stable aluminum base rated for high static load, and casters tested for multi-surface durability. Functional features support flexible, comfortable use across work scenarios. Pneumatic seat height adjustment is controlled via a right-side paddle lever, locking at any position within its adjustment range up to the maximum 540mm seat height. The synchro-tilt mechanism reclines the backrest at a synchronized ratio relative to seat movement, locking in the fully upright position and three intermediate recline angles up to 120 degrees from vertical, with an under-seat tension knob to adjust recline resistance for different user weights. The chair delivers full 360-degree swivel without rotational stops, and smooth low-effort movement across hard wood, tile, and low-pile carpet surfaces, with casters that engage automatic brakes under full user weight. This model fits a range of commercial and residential spaces. In corporate settings, it is suited for executive private offices, client-facing corporate meeting rooms, boardrooms, and high-end executive reception areas, where its formal leather finish coordinates with dark wood or walnut conference and executive desks, and pairs seamlessly with matching brown leather guest seating for cohesive design suites. It also works well in home executive offices, where its classic styling complements both traditional and modern residential decor, and its quiet, smooth-rolling casters are suitable for home hard flooring. For procurement, note the chair ships in a single knockdown carton with all necessary hardware and an included hex key for assembly, with assembly time per unit suitable for in-house facilities setup. Full container load quantities are calculated to support bulk commercial orders for large office fit-outs, and packaging uses standard commercial furniture materials including double-wall corrugated cartons and EPS foam corner protection to minimize transit damage. Material grade for upholstery and internal components aligns with standard commercial specifications, with component details subject to supplier bill of materials confirmation for large custom orders.
