The LINGKEN EXC-WD-LTH-001 is a high-back brown leather executive office chair crafted to align with traditional, formal executive styling. Its structured silhouette features a tall contoured backrest, wide set polished solid walnut wood armrests finished with a glossy clear lacquer, and a five-star base with wood-look trim that coordinates seamlessly with classic wood desk sets. Contrast light stitching along the 1.5 mm thick top-grain brown leather upholstery adds subtle, refined visual detail that elevates formal workspace aesthetics. For construction, the chair is built for long-term heavy use: its internal frame uses 20 mm thick plywood reinforced with solid hardwood bracing, paired with a 3 mm thick steel plate synchro-tilt chassis and chromed steel Class 4 pneumatic cylinder for core structural stability. The seat cushion uses high-density anti-deformation wrapped PU foam rated at 45 kg/m³ with a 60% rebound rate, while the backrest uses contoured high-resilience PU foam with an integrated lumbar pad. Armrests and side panels are cut from polished solid walnut, the five-star base combines a steel inner frame with a powder-coated finish and matching wood-look trim, and 55 mm diameter PU tread casters with steel swivel stems provide reliable mobility. Functional design supports comfortable extended use: the chair enables full 360-degree swivel rotation, pneumatic seat height adjustment with a 120 mm vertical stroke controlled via a right-side lever calibrated to match standard 760 mm desk heights, a 135-degree maximum backrest tilt with 4-position lock settings, and a user-adjustable tilt tension knob to modify recline resistance for different user weights. The fixed wide armrests sit at seated elbow height for consistent forearm support, and the integrated contoured lumbar pad aligns to the natural curve of the lower back to reduce strain during long work sessions. The PU casters move smoothly across both hard flooring and carpet without causing surface damage, and the chair supports a maximum recommended user weight of 250 kg, with a five-star base static load capacity of 1136 kg and caster rolling durability rated for 100000 cycles. This model is well suited for executive private offices for managers and CEOs, boardroom conference rooms for senior meeting participants, dedicated home office studies, and formal senior leadership reception areas for visiting guests. For procurement, the chair is available in 2 finish options, ships as 1 set across 2 cartons with a packaged gross weight of 23 kg per set and 0.26 m³ total carton volume, requires 40 minutes of assembly per unit, and fits 135 sets in a 20GP container at 85% space utilization, making it a practical option for bulk commercial office purchases for management-level workstation configurations.
