This cat tree is pretty and easy to put together. Also, it’s easy to change it up a bit by moving the components around, at least a bit. 
My cat never used it. I have an adult cat and everything of this cat tree is too small for him. I would recommend this product for kittens only, and you will have to get a new one when your cats grow. 
I tried changing the arts around to give my cat more space, but he was never interested in the cat tower, despite the use of treats and catnip....
