The cat tower itself is great however I am only giving it a 3 because the color is totally different than the picture.  The cat tower in the picture is a beige color however the one I received is dark grey.  My cat loves it so I will not return it, but just be warned if you are wanting a beige cat tower, this isn't it.  As for the quality and all that, it is sturdy enough for my cat who is around 9 pounds and doesn't play much.  She just loves to climb to the top platform and look out the window.
