The sofa is composed of three spliced independent curved seat units, all wrapped with full detachable fabric slipcover that can be fully taken off for machine washing to maintain long-term neat appearance. Oversized deep seat cushions and full wrapped backrest are filled with multi-layer high-density rebound foam, delivering soft enveloping sitting experience and anti-sagging performance for long-term use. The smooth integrated curved armrests on both sides eliminate sharp edges, and the skirt-style bottom cover completely hides underlying hardware to keep a uniform minimalist look. Three same-fabric narrow lumbar pillows are provided as standard accessories; clients can swap slipcover material with linen, boucle or velvet, adjust sofa length by adding or reducing modules, and customize any fabric color according to space decoration demand.
