This is nice and sturdy, and the posts are a great size. Some trees have much skinnier sisal posts, which make a big difference in the durability and stability of the tree. It was a little trickier than most to put together. I had to take some parts of it apart again in order to get everything to fit together correctly because it is designed to not have screws show, which is mostly great (and rare). I don't love the top piece. It doesn't easily mold into the "cup" shape, so it's a bit odd looking and bent from being in the box.
