This is a giant cat tree that is great for our four cats.  However, even though sturdy overall the right side wobbles back to front since it only has two posts on that side.  I don't think it is going to fall but the kitties find it disconcerting.  Also the circle parts are small and none of the cats seems to be interested in them.  That being said I am very happy with my purchase.  Our girls love their Christmas present as their old (more traditional tree) had gotten quite old and most of the sisal was gone.
