My cats (3) love my two previous cat trees that are set up in different rooms.  This is not as stable as the other two (I realize this might be an issue because of the height).  However, the like the nubby carpet feel of the other two trees and also the top seat on the other two trees has a higher edge that they can lean up againts.  

Pros: Good price, interesting design
Cons: too light weight and fabric not like nubby carpet
