Although this tree meets the basic need for a cat tree, the top shelf/seat is apparently made of very thin cardboard, such that you have to be careful or it will fold under.  Would not be sufficient for larger, heavier cats.  Fortunately our small 9 pound cat is okay on it.  Would only recommend for smaller weight cats.  

Pros: Meets a basic need, nice carpet.
Cons: Cheaply constructed on top shelf/seat.
