The QILISEN EXEC-HB-GRY-WDACC-01 executive office chair pairs a structured, professional silhouette with refined material detailing to suit formal premium work environments. Its high-back profile features vertically channeled contouring for upper and mid-back support, balanced by fixed padded armrests framed with dark brown wood accents and a vertical brushed metal decorative trim strip along side panels. The chair sits on a polished die-cast aluminum five-star base, creating a stately, proportioned layout that reads as sophisticated rather than overly bulky, with clean lines aligned to formal office design standards. Construction prioritizes long-term durability across all core components. Seat and backrest surfaces are upholstered in 1.2mm thick grey PU faux leather, padded with high-density cold-cured polyurethane foam formulated for consistent support. The internal support structure uses a 1.5mm thick steel inner frame for both seat and back, paired with a 2.5mm thick steel plate synchro-tilt chassis, Class 4 steel gas lift for height adjustment, and dual-wheel polyurethane soft casters with metal bearings. The five-star aluminum base features 2.5mm wall thickness, engineered to deliver stable load bearing across daily use. Core functional features support extended work sessions: 360-degree swivel rotation, 110mm pneumatic seat height adjustment accessible via a side lever, 12-degree synchro backrest recline with adjustable tension control, and a tilt lock to secure the chair in an upright position. The soft PU casters roll smoothly across hard floors and low-pile carpet, while fixed padded armrests provide stable forearm support during focused work. The chair supports a maximum user weight of 159 kg, with all structural components tested to meet rated load and durability benchmarks, including 100,000 caster rolling cycles. This chair is suited for a range of premium work settings: senior executive private offices, formal boardrooms and conference spaces, high-end home office workspaces for remote professionals, executive client reception areas, and enclosed premium co-working private suites. It pairs seamlessly with 760mm height standard office desks to support ergonomic working postures. For procurement planning, note that each chair ships in 2 cartons, with a packaged gross weight of 23 kg per set and total carton volume of 0.26 m³; assembly time per unit is 40 minutes, and 135 sets can be loaded in a 20GP container at 85% space utilization.
