I purchased this cat tree about a year ago, questioned the quality as the price was the lowest I've seen, and both my husband and I were completely surprised at how nice this cat tree was, and the cats, all three of them love it !!  I have a bangle who's very large but surprisingly he can climb to the shelf one down from the very top.  I have two cats that do not get along so one will hide in the upper inclosed compartment while the other lays on the side seat. I love the covering on this tree, not just the same old carpet and so easy to clean !!! 

Pros: Love the material and the price is the lowest I found without giving up quality !! 
Cons: The very stop shelf is a bit wobbly so only my smallest cat will venture up to the very top.
