Product Description

This traditional high-back brown leather executive office chair carries a classic, stately silhouette defined by polished solid wood trim that outlines its structured frame, creating a formal, timeless visual presence aligned with traditional professional design sensibilities. The high, contoured backrest rises to an integrated padded head support section, paired with stationary, leather-padded armrests that sit at a height suited for standard desk use, while a five-star wood base forms a balanced, anchored foundation for the seating assembly.
The chair’s construction pairs premium, durable materials for long-term use: seat and back surfaces are upholstered in top-grain brown finished leather, with layered high-density polyurethane foam padding featuring a soft top layer for consistent, even support. Internal framing includes a 20mm thick plywood seat support panel and solid hardwood back frame, while functional hardware includes a 3mm thick black powder-coated stamped steel swivel-tilt mechanism, chrome-plated steel Class 4 pneumatic gas lift, black PU casters with hard nylon inner hubs, and polished solid wood armrest frames and five-star base with a central metal hub.
Core functional features support flexible, comfortable daily use: the gas lift allows smooth vertical height adjustment, the tilt mechanism supports up to 18 degrees of backward recline from the locked upright position, with a side-mounted rotary dial to adjust recline tension to match user weight, and a locking lever to secure the chair in upright or chosen reclined positions. The brake-free casters roll smoothly across both carpet and hard floor surfaces, and the fixed padded armrests provide steady forearm support during desk work.
This chair is well suited for executive private offices, where its wood-trimmed leather design complements traditional management space aesthetics; it also works as durable, comfortable seating for conference rooms supporting multi-hour meetings, and pairs seamlessly with traditional office suites featuring solid wood desks and cabinet collections. It is designed for adult users for daily desk-based tasks, and pairs appropriately with a full-size executive desk.
For procurement teams, note the chair ships in knock-down format across two cartons, with all required hardware included for assembly that takes roughly 40 minutes per unit. Buyers should account for packaged shipping volume and weight when planning delivery and storage, and confirm ergonomic alignment for intended users prior to bulk purchase, with a reference daily use duration of 8 hours per day subject to individual ergonomic assessment.
