This unbranded vintage brown leather high-back executive swivel office chair, model EXEC-WOOD-BRN-MSG-01, delivers a timeless traditional aesthetic tailored for formal work settings. Its visual design balances rich, warm material tones with structured, refined detailing: vintage brown top-grain cowhide leather upholstery accented by contrast stitching wraps the padded seat and tall backrest, paired with a polished, glossy carved solid hardwood frame, curved fixed wood armrests, and matching five-star base. The upright high-back silhouette aligns with classic executive styling, creating a stately, polished presence paired with coordinating wood office furnishings. Construction prioritizes durable, premium materials across every component. The seat uses 45 kg/m³ high-density polyurethane foam, while the contoured backrest integrates built-in lumbar padding, with both cushion cores supported by a 15mm thick plywood internal frame. The solid hardwood five-star base features a reinforced metal center hub, fitted with black polyurethane twin-wheel casters with metal stems, a Class 3 chrome-plated steel pneumatic gas lift, and a 3mm thick stamped steel tilt chassis with tension adjustment. The leather upholstery is rated for 50000 double rubs of abrasion resistance, casters hold up to 100000 rolling cycles, and the chair supports a recommended static weight capacity of 227 kg, with a 159 kg recommended user weight for daily use. Functional features support comfortable long-duration seated work. The chair offers full 360-degree swivel rotation, 90mm of pneumatic seat height adjustment controlled via a side lever, 15 degrees of backward tilt recline with adjustable tension, and a lock to secure the chair in either upright or full recline positions. Smooth-rolling casters perform reliably on hard floors and low-pile carpet, while an integrated back-focused vibration massage function is adjusted via a side dial. Curved fixed wood armrests are positioned to provide consistent ergonomic elbow support for seated users. This chair is well-suited for executive private offices paired with 2.4 m executive desks, classic home office studies, formal executive boardroom seating, and traditional themed commercial spaces including law firms, financial offices, and traditional hospitality reception areas, supporting 8+ hours of daily desk work.
