This cat tree is somewhat easy to put together. It has everything needed including the Alan Wrench. We have off white walls and a perfect place to put it. Our younger cat "Boo" loves it and he is very athletic. Our other cat "Angel" who is not very athletic does not have much to do with it. She prefers that "boo" is up on it so he is not bothering her. We had another cat tree but sold it.
GREAT product!

Pros: GREAT product!
Cons: None.
