The AIMENGSHI model 3S-QV-MF-2140 is a fixed upholstered three-seat sofa defined by contemporary design, balancing bold visual character and robust functional performance for a range of seating settings. Its signature design features rich purple 100% polyester velvet finished with a grid waffle quilting pattern, supported by a matte black powder-coated square steel tube frame that creates a refined, low-profile modern silhouette. The fixed continuous three-position seat integrates wrap-around arms for a cohesive, streamlined layout, with a balanced proportion that anchors spaces without overwhelming surrounding decor. Constructed for long-term regular use, the sofa is built on an internal kiln-dried solid eucalyptus wood frame, joined with zinc-plated steel corner brackets and hardware for stable rigid support. The seat core uses 40 kg/m³ high-resilience polyurethane foam backed by 3.8 mm diameter sinuous steel springs that evenly distribute user weight, while the backrest is padded with high-density polyurethane foam wrapped in soft polyester fiber. A 20 gsm non-woven interlining sits between the velvet outer layer and foam, with tight grid quilting that prevents fabric shifting over time. The velvet upholstery delivers a 45,000 Martindale abrasion resistance rating, and its stain-resistant surface supports both dry cleaning and targeted spot cleaning. Non-marking 5 mm thick polyethylene glides on the frame legs protect hard flooring from scratches, and the total static load capacity supports seating for three adults. Knock-down leg attachment via pre-attached frame brackets allows straightforward on-site assembly, with a typical assembly time of 40 minutes per set. This sofa works well as primary three-person seating for compact to mid-sized residential living rooms and urban open-plan apartment lounges. Its bold purple upholstery also serves as eye-catching accent seating for creative office boutique reception areas and small studio waiting zones, and can be placed at the foot of a bed or in a bedroom corner to add relaxed extra seating. When paired with side tables and coordinating area rugs, it creates an inviting dedicated conversation zone. Procurement teams should note the product ships as one set across two cartons, with a packaged gross weight of 110 kg and 1.8 m³ total packaging volume, and plan for appropriate delivery access and two-person handling to position the unit in intended spaces.
