It was very easy to put this item together - a big plus! Visually, it's very attractive.  My cats are still getting used to it and the very top level is a tiny bit shaky. I wouldn't get up there, but then again, I'm not a cat. 

The only negative thing I can really say about it is that all the pieces are made of a hard wood-type pressboard and then covered with the thin faux-fur. Standard cat trees are covered cardboard (less sturdy, but a little more give).  Not sure if that is comfortable to sleep on all day, because again, I'm not a cat.
