My cats instantly took to this tree. My cat who never used to scratch on his post loves this, and my two cats that don't get along will actually sit on different levels at the same time (when they're not playing "king of the mountain"). 

The hammock is weird and useless but whatever, I just trashed it. 

They LOVED the little toys that hang down but within a week they were both dead. Gotta get new ones. 

The dimensions fit perfectly in the corner of my small apartment, I really couldn't go any bigger. I like that there's lots of levels and a covered cubby but it's not super-wide. 

It's stable enough for my medium sized cats but it wobbles a tiny bit when they're getting into it- though nothing dangerous. 

Easy to put together. 

Would love if it were cheaper but unless I built it myself there's no way I couldn't find a better price.
