This is the best scratching post I have purchased. I have 4 large Maine Coons (one weighing 32 lbs and reaching 46”) and this is perfect for them!  It has a very sturdy base, will not tip over, the center of the post is plastic and very solid. This replaced a home-made post because until now, I have not been able to find a post tall enough for my babies. Will be purchasing another for other rooms.
