This is the second cat tree we've bought for our four year old cat.  I bought a taller one thinking that he would love it as much as the last one but no deal.  He never climbs this one to the top, almost like he's scared of being that high.  Also, the rope around the base gets lots of scratching but hasn't held up near as well as the last one.  One post is already frayed beyond repair and it's not even a year old yet.  

Pros: Lots of choices for climbing and sitting
Cons: Doesn't hold up well to normal wear and tear from one cat
