In the past, I have objected to getting my cats a tree because I find them unappealing, especially after they are torn and scratched. But this tree looked pleasing to me and I felt my cats deserved a new playground since they were looking bored. This tree is attractive and assembly was fast and easy, after arriving in 2 short days. It's covered with a smooth, slick furry fabric so my cats' claws just slide off of it. I think the fabric looks better than carpet. It's pretty tall which is what I wanted. Plenty of levels for a few cats to play on all at once. All of my cats love it. Some even sleep on the highest level at night. I think it makes them feel safe. 

Pros: Easy assembly. The fur holds up to sharp claws. 
Cons: Cats are tearing off the sisal rope. It frays and leaves fibers on the floor.
