This is the 2nd tree I've ordered from this manufacturer and the 2nd from Wayfair (which has the best prices). It was easy to put together, even with the help I had. It is sturdy and also nice looking. My first cat tree I gave to a friend. It needed the poles redone but other wise was in good shape. Her cats love it anyway. The box is well liked by my cats. But the top two bunks are the favorite. I am very happy with my purchase!!
