I ordered this cat tree because of its measurements. The two top perches are large and the condo is also larger than other condos on other trees. One of my cats is napping on it as I write. It [...] was very easy to assemble. I put a towel over the posts so I could grab it better as it needs to be tighten very good. That way when cats jump on it it won't get loose. Overall the tree is looking so beautiful, it is so soft and very good quality. I am very impressed and so are my cats. I have two girls. One of them went right into the house as I was unpacking it and fell asleep in it. Couldn't get her out..she loved it. My cats use all of the cat tree.. I am very happy with it. Highly recommended!! Thank you!
