The KETAI High Back Brown Leather Executive Office Chair (model EXE-WD-BRN-001) balances traditional formal styling with functional ergonomic support for professional work environments. Visually, the chair features structured, stitched contoured upholstery panels in a rich brown tone, paired with fixed armrests and a five-star base finished in polished mahogany-toned stained solid hardwood, creating a refined, authoritative silhouette aligned with classic executive office aesthetics. Clean, tailored lines and the warm wood finish complement high-end formal workspace design without unnecessary ornamentation. The full assembly measures 750 millimeters wide, 810 millimeters deep, and 1300 millimeters tall, with a 700-millimeter diameter five-star base that maintains a stable footprint without crowding desk areas. Construction prioritizes durable, long-wearing components: seat and back surfaces use 1.2mm thick brown top-grain cowhide upholstery rated for 50,000 abrasion cycles, while cushion cores are built from layered 45 kg/m³ high-density polyurethane foam with 45% resilience, meeting CA117 fire-retardant standards. Internal load-bearing structure relies on a 2.5mm thick stamped steel tilt and swivel chassis, a Class 3 black powder-coated steel pneumatic gas lift, and solid hardwood armrests and base with a static load rating of 1136 kilograms. Black polyurethane dual-wheel casters with nylon hubs attach to each point of the five-star base. Core functional features support extended seated work: the chair enables 360-degree full rotation around its central axis, lever-operated pneumatic seat height adjustment with 100 millimeters of travel to a maximum seat height of 570 millimeters, and a knee-tilt mechanism with adjustable tension and an upright position lock. The casters deliver smooth rolling across carpeted surfaces, and the 750-millimeter tall high back provides full upper body support for users during long work sessions. The fixed armrests sit 200 millimeters above the seat for consistent forearm support, and the chair supports a maximum user weight of 159 kilograms. This chair is designed primarily for private executive offices and senior management workspaces, ideal for users who spend extended hours seated and prefer formal, traditional office styling. For procurement planning, note that each unit ships in 2 cartons with a total packaged gross weight of 23 kilograms and total carton volume of 0.26 cubic meters, with a 40-minute per-set assembly time. A 20GP container can hold 135 sets at 85% space utilization, supporting bulk order planning for corporate office fit-outs.
