the parts do not come labeled so you have to get a measuring tape to find out which pole is what- the board aren’t labeled so you have to flip them upside down and match the pictures. Some pieces came in damaged. The cat tree is seperated into 3 parts and only 1 of the parts goes up to the ceiling and even then it doesn’t feel very secured- the other pieces are connected loosely. 
I feel if my cats get too rowdy playing there is a chance the whole thing could fall over but it does its job of providing and upward climb for my tree dwelling cat.
It would’ve been perfect otherwise
