This cat tower is beautiful but I wish it would have mentioned that the pedestals are very unstable for any cat larger than s kitten...Honestly if you have cats over 10-12 pounds I would not get this.... My cats are adults and range from 16 to 22 pounds. They are very active and this cat tower is no match for them. I had it assembled in no time it was very easy! My cats immediately went to play on it, the lower tower was the most wobbly, my cat went to climb onto it and when it moved under his feet he just launched to the next level.... Once he got to the top to play with the dangling mouse I new there was going to be trouble! I was holding the pedestal while he played on top so he didn't fall off due to losing his balance! It is an unsafe height for him to fall from.... Other than that the rest of the tower is well built. 
Conclusion: I was offered a full refund and ordered a much sturdier tower with a wider base. I hope the new one is better.
