Given the fact my cats get the zoomies and chase eachother and are maniacs, this cat tower is sturdy enough to where they can jump  full speed straight to the top and it only wobbles a little. Also, set-up was easy and took less than an hour! It matches the jungle vibes I have going for this corner. Sprinkled a bit of catnip on every step and they took to it right away! Very pleased and worth the wait for it to come back into stock )
