The KETAI EXE-WD-LTH-001 is a high-back black leather executive office chair designed to deliver a traditional, polished professional aesthetic paired with reliable, ergonomic functional performance. Its visual design balances refined material contrast and structured, authoritative proportions: black top-grain leather upholstery accented with neat contrast stitching forms the tall, supportive back and generously sized seat, paired with smoothly finished solid wood armrests and a matching five-star base that adds warm, timeless textural depth to the sleek black leather profile. The open layout between armrests accommodates a broad range of user builds, while the tall backrest integrates a dedicated lumbar support zone aligned to the natural curve of the lower spine for sustained seated comfort. Constructed for long-term heavy use, the chair’s seat and back are wrapped in 1.2mm thick top-grain cowhide, padded with high-density molded polyurethane foam with no added down filler, secured to an internal 15mm plywood frame reinforced with steel for structural stability. Armrests feature a solid polished wood frame with a lacquer finish, topped with padded leather for soft arm support, while the five-star solid wood base is coated in clear protective lacquer to resist surface wear. Mechanical components include a steel synchro-tilt chassis, chrome-plated Class 3 gas lift, and nylon dual-wheel casters engineered for smooth movement across both carpet and hard floor surfaces. Core functional features support flexible, comfortable use across long work sessions: a side-lever operated pneumatic adjustment controls seat height, the synchro tilt mechanism reclines the back and seat at a balanced ratio with adjustable tension and a secure upright lock position, full 360-degree swivel enables easy multi-directional access to desk surfaces, and the robust weight capacity supports a wide range of users. The chair is ideally suited for executive private offices paired with senior management workstations that call for a traditional professional aesthetic, as well as boardroom meeting spaces to seat conference leaders and meeting participants. Procurement teams should note that each unit ships in two cartons, with a straightforward assembly process for on-site setup. The product’s durable upholstery, long-cycle rated mechanical components, and timeless design make it a sound long-term furnishing investment for spaces prioritizing both executive presence and consistent daily functionality.
