BEST CAT TREE EVER!!!! I have purchased multiple cat trees through the years; even other ones from this manufacturer and NONE of them come even close to how awesome this one is!!!! Seriously, I have several cats; some of which are over 20lbs (not fat cats. but inordinately large cats), this tree doesn't even wobble, shake, or sway when they are racing around and go from the couch to the tree. Every other cat climber we have owned were junk! Anyone that wants to have their cats safe when they are climbing and being crazy, this is the only tree/climber I would recommend.
