I acquired a shelter cat, a 4-yr-old female Siamese mix who's about 8 lbs, about a year ago. I work from home a lot, and she's requiring more attention than I expected from having had previous cats. She's getting spoiled--balls, battery powered mice, hexbug cat toys, but this tree is now her favorite. She's used the cat condo (closed box), the ladder (still not too sure about that), but curling up on one of the top perches is her favorite. I'm guessing that since she's quit hiding under the beds any more, this gives her a feeling of security by being able to see from that height--and it is high! Easy to put together--just be sure you sort out the hardware first, there's one bolt that's bigger than the rest. Good construction and materials, better price on sale here than lesser-quality products at the big box pet stores.
