I love this cat tree because it's so big and very nice to look at but unfortunately it's very wobbly. Maybe it's because the cat tree is on hard wood floor instead of carpet but my cats jump on it and it shakes. I also have one of the sisal rope pieces that is defective and won't screw on to the tower. Disappointed that I have a defective piece... Hopefully no one else has this problem because this tree is beautiful and I would've given this review 5 stars if it weren't for the problems I came across.
