The LINGKEN Model 6131 High-Back Black Leather Executive Office Chair delivers a refined, traditional executive aesthetic tailored to premium seated environments, anchored by warm solid wood accents and a sleek monochrome black upholstered form. Its tall, structured high-back silhouette frames a continuous padded support surface, paired with curved carved solid wood armrests positioned to hold padded elbow rests at natural seated height, and a matching solid wood 5-star base that balances visual warmth with structural rigidity. Built for lasting daily use, the chair’s seat and backrest are upholstered in 1.5mm thick black top-grain cowhide, stitched with heavy-duty nylon thread at a consistent 10 stitches per inch for durable, clean seam lines. Beneath the upholstery, high-resilience polyurethane foam at 40 kg/m³ forms the padded core, with a 90mm thick seat cushion, 70mm thick backrest padding, and a raised 240mm contoured lumbar zone integrated directly into the backrest structure, plus an extended padded upper section to support the head and neck. The internal support frame uses an 18mm engineered plywood core reinforced with solid wood bracing; armrests are finished with a clear environmental lacquer, while the 5-star base incorporates a steel-reinforced central hub for added stability. Functional components include a black powder-coated SGS-certified steel gas lift, a 3mm thick steel plate lockable airplane-style tilt chassis, and 50mm diameter black polyurethane dual-wheel mute casters. Core functional features support comfortable long-duration seated work: full 360-degree swivel rotation, pneumatic seat height adjustment controlled via a side under-seat lever, 15-degree backward recline with adjustable tension and position lock, and low-noise smooth rolling across hardwood, tile, and low-pile carpeted surfaces. The fixed wide armrests provide steady upper body support, and the chair is engineered to accommodate 4+ hours of continuous seated use. This model fits a range of premium spaces: it is well suited for executive private offices for CEOs, general managers, and directors, formal boardrooms as head-of-table seating, high-end home office setups for remote executives, and VIP guest seating in upscale commercial reception areas. For procurement planning, note that each unit ships in 2 cartons, with an 40-minute assembly time per set, a packaged gross weight of 23kg per set, and a maximum static load capacity of 250kg, with a recommended user weight limit of 159kg. Buyers should also confirm floor compatibility matches target installation spaces, as the casters are designed for hard flooring and low-pile carpet surfaces.
