I am very happy with this Tree, our three cats love it and are on it all of the time.  They quit clawing on our furniture Immediately after I presented this to them.  And, I set it in front of our living room window so that they no longer have to jump approximately 4 feet up from the floor.  This Tree also acts like a ladder for them.  At any rate, this Tree is well constructed, our 20 pound cat has yet to topple it when he jumps down from the top to the floor.  He loves laying on the top tray and our youngest loves laying beneath him and playing with the toy.  But, so far, they haven't messed with the rope yet but I think that will come soon.  I was amazed when I saw the rope as it is the same exact size that we had as mooring lines on our ship.
All in all, an Excellent Product, Safe, Secure, Heavy and Cat Approved, Big Time!!
