I chose this tree because of the great reviews it got, and I am very glad I did! It was very easy to put together, and is very sturdy. Pretty much exactly as described. DO NOT USE THE BALL/STRING Toy that is included. It is dangerous, and meant "for display purposes only" My cat loves this thing. When the sun comes up in the morning and shines on the bottom level, so he lays there and plays with the sisal rope. Then he often naps in the little house or sits on the upper levels and watches the birds outside. We are very happy with this purchase!
