As stated by others, it could be more stable. I have it in a corner with a 15 pound dumbbell on the bottom but I can still hear it hit the wall when my cats jump on or off it. My purpose for this tree is for the cats to use the top platform to look out the window I placed it next to. I also wanted to see if they'd use the bowl shaped addition (they haven't yet after having it for a few weeks). It is used for its primary purpose and as a scratch post; I've only seen one of my cats in the dome box once and they don't have any interest in the rope.

Pros: good value, easy to assemble
