It’s a great piece and the cat loved it, we used it for two year. Throughout the years the longest pole required to be tightened. I don’t if because my is pretty rough on these cat condos (he is 5 years old and it’s his second cat condo) After the two years the  longest pole became threaded because it required to be tightened. Once the biggest pole could not tightened it became unstable and would wobble when he climbed. Eventually one morning I woke and had tipped over. I have small children to I had to get rid of it. Again I don’t know if it’s just my cat or the piece but my last cat condo at least lasted 4years this one only gave me two.
