It does take some doing to put this tree together. There are no written instructions or identification,only pictures. My roommate and her dad put it together. It does come with a screwdriver and all the buts and screws etc. are in one package. Two hours to assemble, and voila, this Cat Tree stands before you units glory. My cats have not taken to it yet. I SURE hope they do. It looks the way I hoped it would. After updating my furniture in the living room, I wanted the cats to have their own new, functional piece, to scratch to their heart's content. Still, the tree is gorgeous!
