The Mid-Back Walnut Bentwood Black Leather Swivel Office Chair (model 1702B-XD) is an unbranded seating solution defined by a streamlined, mid-century-inspired silhouette. Its continuous walnut veneer bent plywood shell forms integrated wrap-around fixed armrests that curve seamlessly from the mid-height backrest to the front edge of the seat, creating a cohesive, polished visual profile balanced by a polished chrome-plated five-star base and smooth black upholstery. The chair’s layout follows standard ergonomic office seating proportions, with padding positioned to support upright working postures without bulky overhang that would disrupt sightlines or crowd adjacent work surfaces. Construction pairs the 12mm bent molded plywood structural shell with high-resilience polyurethane foam padding: 80mm thick in the seat cushion and 50mm thick in the backrest, upholstered in smooth black PU faux leather. The five-star base is constructed from polished chrome-plated steel, fitted with 50mm black nylon twin-wheel universal casters, and connected to the seat via a chromed steel Class 3 pneumatic cylinder controlled by a black nylon-coated steel adjustment lever positioned under the right side of the seat. All connections use steel hardware for structural durability. Core functional features include full 360-degree swivel rotation, pneumatic seat height adjustment aligned to standard desk heights, and omnidirectional rolling mobility suitable for hard floors and low-pile carpet. The fixed integrated armrests provide stable upper body support at a set position, and the seat offers a lockable rear tilt function with adjustable tension for personalized comfort during work or short breaks. The non-porous PU upholstery supports simple wipe-clean maintenance with mild detergent, resisting common office spills for long-term upkeep, while the five-point base geometry delivers stable support to prevent tipping during regular use. A 3-year warranty covers structural components under normal operating conditions. This chair suits a wide range of commercial and residential spaces. It fits private executive office workstations with its formal walnut and black finish, complements home office studies with its understated contemporary styling, and works effectively in conference and meeting rooms where its mid-back profile avoids blocking cross-table sightlines, while swivel functionality supports multi-directional interaction. It is also appropriate for executive reception areas, co-working flexible desk-sharing spaces, and hotel business centers, where its durable build, easy-care surfaces, and classic aesthetic hold up to frequent, varied use. Procurement teams should note several key considerations. Color and material customization options are available, including genuine black leather upholstery upgrades, alternate wood finish shells, aluminum alloy base upgrades, and soft PU casters optimized for hard floors, all available directly from OEM suppliers. The chair ships in single knock-down packaging in a 5-layer corrugated carton with EPS foam protection, with assembly taking up to 50 minutes. Container loading capacities support bulk order planning, and all structural and performance specifications align with mid-market contract furniture standards, though final material grades should be confirmed with suppliers prior to large-scale orders.
