The Asymmetric Wrap-Back 360° Swivel Lounge Armchair from JUESHANGDA, model SWL-ASYM840-CHROME, is a sculptural contemporary upholstered seating piece defined by its distinctive asymmetrical wrap-around back and arm enclosure. This structural design creates an enveloping, soft seating silhouette supported by a sleek polished metal base, delivering a refined visual presence that aligns with contemporary, organic modern, minimalist, and post-modern interior design schemes. Constructed for long-term durability, the chair’s internal load frame is built from welded steel tubing, with sinuous S-shaped steel springs forming the seat support layer above a bent plywood support board. The seating surfaces are padded with high-resilience polyurethane foam wrapped in polyfiber, delivering medium-firm support calibrated for extended continuous lounge seating, with reinforced stress-point seams stitched with high-tenacity polyester thread for structural integrity. The outer upholstery uses abrasion-resistant tech fabric, mounted atop a polished chrome-plated steel disc base fitted with an enclosed steel ball bearing swivel assembly that enables full 360-degree rotation with no forced return mechanism. A non-marking EVA rubber pad affixed to the base underside prevents floor scratches, making the chair safe for use on hardwood, tile, polished concrete, and low-pile carpeted surfaces. The chair is ideal for residential placement in living room lounge zones or dedicated reading nooks, and equally suited for commercial settings including hotel lobbies, co-working break areas, and boutique reception spaces. It can be deployed as a standalone accent chair or paired with a matching ottoman for enhanced lounge comfort, and supports custom two-tone upholstery color blocking alongside 8 standard color variants to coordinate with existing decor. For procurement planning, note the chair ships fully assembled with no on-site fastener installation required, delivered in two cartons per set. Delivery requires a minimum clear doorway width for entry. The product is covered by a 1-year warranty, with a rated static weight capacity to support regular daily use.
