Product Description

The High-Back Black Leather Executive Office Chair with Mahogany Wood Accents, model EXEC-WD-001, carries a traditional executive aesthetic defined by its tall, structured silhouette and warm polished wood details paired with sleek black upholstery. Its formal, stately design centers on a high, contoured segmented back and fixed wood armrests, anchored by a five-star wood base that balances substantial visual presence with clean, classic lines suitable for premium professional settings. The chair is built for long-term durability with carefully selected materials. Seat and back surfaces are upholstered in 1.2mm thick black top-grain match leather, stitched with heavy-duty contrast polyester thread at an 8mm seam pitch for a tailored finish. Armrest frames and the five-star base are crafted from polished mahogany-finished solid hardwood, with armrest tops wrapped in matching padded leather for soft contact. Internal structures include an 18mm thick multi-layer plywood frame for the seat and back, supported by 40D high-resilience high-density polyurethane foam padding across the seat and three-zone back support sections. Core functional components include a Class 4 carbon steel pneumatic gas lift, 3mm thick cold-rolled steel tilt mechanism plate, and black nylon dual-wheel hooded casters. Functional features are engineered for all-day seated comfort and ease of use. The single-lever pneumatic seat height adjustment delivers 180mm of vertical travel, while the center-tilt mechanism includes an under-seat tension knob for customized resistance and a single-position upright lock for focused work, with three suggested lock positions supporting a maximum 18-degree recline. The chair swivels 360 degrees, with five dual-wheel casters that move smoothly across hard floors and low-pile carpet, and three-zone padded back support that cradles the lumbar, mid-back, and upper back. It supports a maximum user weight of 200 kg, with caster durability rated for 100,000 rolling cycles and tilt mechanism durability rated for 300,000 cycles. This chair is well-suited for senior management private offices, middle and senior manager workstations supporting 8+ hours of daily use, head-of-table boardroom seating, high-end home office layouts, and executive reception waiting areas where a prestigious, formal design creates a polished first impression. It pairs optimally with a 2.4 m executive desk. For procurement, note the product ships as one set across two cartons, with 40 minutes of required assembly per unit; a 20-foot GP container holds 135 sets at 85% space utilization. The unbranded model does not carry third-party performance certifications, so buyers should align specifications with intended use frequency and space requirements before purchase.
