This post is not sturdy at all.  The cats have knocked it over several times.  I bought it mainly for the cats to use the sisal scratching post which they sometimes use.  If the cats want to jump up on it, it wobbles a lot and scares them.  I have another cat tree that they use to sit on and sleep in so this one is just for sharpening their claws.  It would be better to spend your money on something heavier and sturdier.

Pros: They do like the sisal post.  Does not take up much room.
Cons: Too wobbly.  Would be better if it could be secured to the wall or floor.
