Despite its stability, it is advisable to lay down the barrel directly on a wall or in a corner, thus it is additionally stabilized. My cat is in fact quite able to push the barrel in his "scratch orgies" (on smooth ground) throughout the room. The ton not to fall, but it migrates ;-)
The simple design of each home furnishings adapts fine. For everyone who wants to lay down a monstrous cat tree or looking for an additional way to scratch his fur noses, scratch ton is a very good choice. It is also high enough that a normal-sized cat claws at whetting may well long stretch it. Installed in a window, it also offers a great vantage.
