What kind of sofa should I put in the living room when I change it into table tennis?

You can put a sofa with a small table tennis table. By using the double-sided sofa backrest and using hard materials on the back of the sofa near the back, table tennis can bounce normally on it like an ordinary table tennis table. The front of the sofa backrest is an ordinary soft backrest, so that you can use the soft backrest when sitting on the sofa. When you need entertainment, you can use the sofa as a table tennis table by adjusting the position of the backrest of the sofa, and then the sofa becomes a table tennis table.
