This is an excellent buy and am very pleased. Very easy to put together and there were instructions with picture in the box. It is heavy, my cat is big (17 lb +) and he fits on this fine, it does a wobble when he jumps off of the top but I have it in a place where I can attach so it does not wobble. I recommend this item. Just arrived today. All the parts were fine and worked and fit nicely together. It may take two people to put together. CT cat is still checking it out. I put catnip on it so he would get on it since he is older and to entice him.
