It was easy to put together, comes with directions. I did it all by myself! Made well, sturdy, perfect height. I rubbed some catnip on it then I put one of my cats on top of one of the shelves, my other cats came right away to check it out.I rubbed some catnip on all the shelves. Now they like to sit on it and watch squirrels, because it is next to a window. Each got their own shelf! No more fighting for the best view.
