My cats LOVE this cat tree. They were all over it before I could even get it together. I read all the reviews before selecting the one I thought was best for us. I screwed all the parts in so tightly when putting it together that for me, it is very sturdy. I had read a review that said it was wobbly. This is not my experience at all. It fits perfectly in a corner in my small Manhattan studio apartment and looks great. My big older cat jumps up and gets in the house and my little, younger, more agile cat is all over it all the time. They now spend about 75% of their day on the cat tree, my little cat even more. I just bought some new furniture for my apartment which I did not want them to scratch. When I bought them this, they go to the scratching posts on it. They leave all my new furniture completely alone. I had another much smaller cat tree with two little levels that I paid as much for in a retail store as this tree. This tree is far superior and looks much nicer. Highly recommend.
