This is the first cat tree we purchased and although sturdy and easy assembly, some of the components needed to be removed because my cats are too big for them. Even without the smaller parts, they still love the tree and I was so impressed with it, that I purchased another product of this manufacturer for them that is sized better for larger cats. They love and use both ALL THE TIME! Pros: Easy assembly, sturdy, looks great Cons: Best for smaller sized cats. Maybe 6-9 pounds.
