So far it's great. A little wobbly but not too bad. We left two of the ladders off so the cats would have more nap time options. It was easy enough for me to put together by myself even with the page of only somewhat helpful instructions. Our largest cat sort of spills out of the round bed-thing's but he's not complaining and he and the kittens have been climbing up and down, playing with each other, and napping on it in various locations all day.
