My two older cats love this tree.  Good size and easy to put together, takes awhile but not hard.  The places where you hang the balls are in poor places but my cats balls are still hanging plus I put a stick toy through one of the places - cats just have a hard time getting to them to really go crazy. Tree is well built and stands up well.  I would have liked the platforms to be a little larger but you know a cat can sleep anywhere and they manage to do just fine.  Buy this - great price and good quality.
