I am using the cat tree, as it is sturdy and has a high platform to enable my kitten to see out the window, but am disappointed in what the description claims is a "cozy:" retreat. The "faux fur" covering is nothing more than a very thin, loose, soft fabric that does not mitigate at all the hardness of the underlying wood. To me, cozy means comfortable, and there is nothing about the platforms or the retreat space that is comfortable.

Pros: Easy to assemble, sturdy and durable.
Cons: Not comfortable to sleep on/in.
