I really like this cat tree!  I actually bought two of them, for two cats who live separate lives in separate rooms of my house.  The cat trees were both pretty easy to put together.  One of them was missing the packet of hardware but one call to the customer support number and the hardware was sent within days!  Reviews from the cats themselves are mixed at this point.  We put the trees in front of windows to encourage the cats to boldly go...  The lighter and smaller cat doesn't seem too interested in the cat tree yet and the heavier, larger cat finds the tree a bit wobbly.  But I have grand hopes that both cats will "come around" soon!
