This is a great tree, and is a lot cheaper than a similar one you can buy in a pet store. I love that it comes apart.  Even though it might not be as sturdy it's worth it for when you have to move it. My cats play on it all the time and love to sleep on the top tiers. The only bad thing I can say about it is that you have to tighten the pieces down every once in a while, but that is easy if you keep the tool that it comes with.
