The M Collection" sofa series is the first product system launched by the famous industrial designer Yang Mingjie in cooperation with Expocasa. The sofa backboard, bottom board, seat cushion, back cushion, armrest, etc. are all independent modular units. Through standardized installation and combination methods, single-seat, double-seat, triple-seat, and corner unit can be formed to adapt to different home spaces and usage scenarios.

The back panel of the independent module of the sofa is combined with two cushions of different sizes. Different placement methods provide users with different sitting experiences. The detachable small screens on both sides of the backboard become a side table for storage. Combined with the gap left by the bottom board, mobile phones, PADs, books, remote controls, etc. in various sofa usage scenarios have a proper placement space, solving the problem of messy items on independent coffee tables in traditional sofa usage scenarios. At the same time, a relatively private corner is also formed.
