People have crazy ways of expressing their maddening creativity that is so dying to come into existence. But, what maddening creativity could possibly allow someone to sit on a cactus sofa. I am assuming that it is made of some real ones, as no particular explanation is given for this. However, even if you had balls enough to sit on it, take my word for it, it would cause you real trouble in the area where you would not want. So be cautious.
