The “Champ” sofa is not only a stylish furniture for your home, but you can 影梭 fold the backrest up to form a punching bag for your workouts. The German designer says:
the risk of injury is so low that even children can play with it without any danger.
We would think, the stability could also be pretty low, so maybe only children can play with it without any danger (of it breaking or tipping over the couch).
Anyway, you can get it for an undisclosed amount of greens (or rather Euros).
