This Cat tree was really easy to put together and our cat really likes it.  We have it positioned in a corner which helps for stability with our large cat. The only think I wish was different is if it all fit within the footprint of the base plate so that when it's pushed into the corner all the platforms are flush with the walls. As is, some of them stick out further than that base footprint, so the base is a few inches out from the corner.  Not really a big deal at all, just something I had noticed.
