I read other reviews about other trees needing weights and being top heavy.  And given we have a cat and not kitten, it concerned us.  Plus to get a good view of the golfers, Coco needed a decent perch with a cat sized bed on top.
The reason we were even looking was our other one needed a chair by it, as straight up and no one used condos.
I looked at every one available.  Height, steadiness, decent bed at top and not having to be a kitten or leopard to get to top.
This is wonderful, checks off all the boxes.  Hop, hop, hop, at the top.
I dont think it needs to be as heavy as it is, that only issue.  But that is being picky, better than having to put on a weight.
I would recommend to anyone.
