The entire sofa is composed of four independent modular components. It is simple and convenient to disassemble and reassemble. It can be freely arranged and combined according to the size of the house, the layout of the space, and personal preferences, allowing for the creation of various seating arrangements. The customized flexible combination design enables compact placement in small houses without occupying space, and allows for flexible matching in large houses to create an elegant appearance. It perfectly fits various room sizes and home decoration layouts, offering extremely strong flexibility in home matching. The cloud-like thickened cushion provides a relaxing and pressure-relieving feeling. The high-density filling is soft and supple for long sitting. The sofa is equipped with thickened and widened high-elasticity cushions, and the interior selects high-density high-quality foam combined with silent serrated springs for double filling. It has good elasticity, is soft and skin-friendly, and the seat hugs the body curve gently like a cloud, with a soft and moderate feeling that does not sink. The overall integrated base of the seat is designed for reinforcement, strengthening the overall structural strength of the sofa. It distributes the force evenly and stably, is durable and resistant to wear and tear, and maintains a long-lasting comfortable feeling as it is new even after a long time of use.
