VERY unsteady, my cats won't even go above the second level because it rocks and shakes so much, before you ask - yes all the screws are tightened. Also the hammock does not lay as low as pictured - i can barely fit my hand in there & my cats are unable to get into it. But the quality of the fabric and scratching posts are great. So debating keeping because returning might be even more of a hassle, but hey. You get what you pay for
