I'm pleased with every aspect of this cat tree. I just got a new kitten and he likes getting on it already although he's not quite ready for the top tier. My other cat likes the base scratcher and lounging on the base. It's a heavy tree and comes with an attachment to secure it to the wall but I prefer to just sit some weight in the middle of the base. In all honesty an adult cat would have a hard time turning it over. I also like the fact that it has lots going on but doesn't take up a large section of space and is not so high that it blocks the whole window. It's a nice looking cat tree. The cats are using the scratchers and did so almost immediately. It was easy to put together.  The price and free shipping were also very nice.
