I purchased this cat tree a few years ago when I adopted my youngest kitty.
Pros - well made, big, sturdy, constructed with real wood and carpet
Cons - I wish the scratching posts were made with sisal, rather than carpet.  
I removed the carpet from the posts and replaced with sisal, but the youngest cat still won't use the sisal posts for scratching and now uses my carpeted steps tas a scratching board. 
Otherwise, I would give a 5 star rating.
