Very small and unstable. The cat toy came broken. I have the tree wedged between my couch and the wall so it won't fall over. I recommend this for kittens only as my 7 pound cats can't fit inside the bottom cylinder. Also, the top platform is for sitting only. My 7 pound cats are too large to lay down on it. Oh well. I'm keeping it because paying for shipping back means I barely get a refund.
