The cats love this cat tree and have a lot of fun playing on it.  A few issues that we have had with it are that the very top landing is made of foam so it's going to mash down pretty quickly.  One of the screws was too short so we had to replace it, and the strings on the hammock started to fray so we had to glue the top of them to stop the fraying.  Overall we do like the cat tree and it is really sturdy.
