The LINGKEN EXE-WD-BR-L01 high-back brown leather executive swivel office chair blends traditional formal styling with purpose-built ergonomic structure for professional settings. Its visual profile features a tall, structured 700mm high backrest framed by polished solid mahogany-finish hardwood trim and curved fixed wood armrests, paired with a coordinating lacquered solid hardwood five-prong swivel base. The rich brown top-grain cowhide upholstery delivers a refined, timeless appearance, with uniform 8 stitches per 30mm seam pitch creating clean, tailored lines across the seat and back. At maximum adjustable height, the chair measures 730 x 720 x 1280 mm, with a 610mm wide, 530mm deep seat, 560mm wide backrest, 230mm armrest height above the seat, and 686mm diameter five-star base, presenting a substantial, authoritative silhouette suited to formal spaces. Constructed for long-term durability, the chair uses 15mm thick plywood as the internal backrest support, with high-density 45 kg/m³ molded polyurethane foam padding delivering 60% rebound rate for consistent cushioning. The height adjustment system relies on a Class 4 steel pneumatic cylinder rated for 120000 adjustment cycles, paired with a 3mm thick steel plate tilt mechanism and zinc-plated steel fasteners and linkage for structural stability. The leather upholstery resists wear through 50000 Martindale rubs, while black nylon hooded twin-wheel casters attach to the solid wood base. Functional features include full 360-degree swivel rotation, 70mm of vertical seat height adjustment controlled by a right-side under-seat lever, 15-degree maximum backrest recline with an upright lock position, variable tilt tension adjustment to match user weight, smooth rolling across hard floors and low-pile carpet, contoured segmented integrated lumbar support aligned to the natural lower back curve, and stable fixed padded armrests positioned for desk-height forearm support. The chair supports a 227 kg recommended static load, with a 27 kg net weight. This chair is ideally suited for executive private offices serving CEO and manager workstations, formal boardroom meeting spaces, home offices for senior professionals, government and official reception offices, premium client meeting areas, and daily desk work sessions lasting 4 to 8 hours. Procurement teams should note each unit ships in 2 cartons with a total packaged gross weight of 23 kg, requires 40 minutes of assembly per set, and allows for 135 units per 20GP container at 85% space utilization to plan logistics and installation timelines appropriately. The traditional high-back design pairs professional aesthetic appeal with functional support for long workday use across formal professional environments.
