The whole sofa is upholstered in smooth matte white soft fabric with delicate touch and anti-fouling treatment for easy daily cleaning. Every independent cubic seat module can be freely combined to form straight, L-shaped or asymmetrical layouts according to space size. Seat cushions and back pillows are filled with a blend of high-density foam and down clusters, bringing a deep sinking cloud-like sitting experience while maintaining long-term supporting performance without collapse. Wide integrated square armrests keep the overall lines neat and smooth, low hidden black non-slip base feet create a suspended lightweight visual effect, and all fabric covers are fully removable for convenient washing. Multiple fabric choices including suede, linen and microfiber are provided for interior designers, property developers and furniture wholesale clients.
