产品描述

The Armless High-Back Walnut Bentwood Swivel Lounge Chair features a sleek, minimalist silhouette defined by a single-piece tapered high-back bentwood shell, finished in warm walnut veneer with a contrasting natural light wood-toned exposed layered ply edge along its entire perimeter. It pairs this organic wood form with a polished chrome 4-prong spider base, creating a balanced visual contrast between warm natural material and reflective metal suited for both contemporary and mid-century modern design schemes. The chair’s core structure is built around a bent plywood shell topped with a clear polyurethane lacquer coat for a smooth, durable surface, supported by a polished chrome-plated Class 3 pneumatic gas lift connected to the wide, stable 4-prong base. Each base leg is fitted with non-marking floor glides, and internal assembly uses zinc-plated steel hardware for secure joints. The seat and back are fitted with layered foam padding for consistent comfort across long seating sessions. Key functional features include smooth 360-degree rotation without a rotational lock, pneumatic seat height adjustment that locks at any preferred position within its travel range, and a fixed non-rolling design suited for static placement. The continuous curved shell contour delivers full lumbar to upper back support for relaxed upright or lightly reclined postures, while the smooth sealed wood surface wipes clean easily with a dry or lightly dampened cloth, eliminating the need for specialized upholstery care. Soft glide tips prevent scuffs and scratches on hard flooring surfaces, and the wide base footprint resists tipping during normal swiveling and seated movement. This chair works effectively across a range of spaces, including office reception and waiting areas, casual home office seating zones, modern living rooms as accent seating, co-working breakout spaces, hotel lobbies, executive lounges, and design showrooms where its sculptural form can serve as a visual focal point. For procurement, note that the chair ships as knock-down flat-pack units with assembly hardware included, designed for straightforward on-site assembly. Confirm specific material specifications including base alloy composition, gas lift certification details, finish VOC content, and glide material with suppliers prior to bulk orders, as these elements require formal supplier documentation for full project specification alignment.
