It is a tad wobbly. Not tip over wobbly, but when my two girls get rambunctious it can vibrate and shake a bit. So far they love the scratching areas, the feather, and the platform. Only one of them has jumped into the crows nest and laid there for a few minutes. Neither have spent any prolonged time in the bottom but honestly I didn’t expect them to. The black and white really fits my decor, and it’s different so I love it. They love it!
