This is really a great tree for the price - kitties have already started checking it out almost immediately. I will say CLOSELY follow the instructions and watch the video or you will put things on backwards... like I did! I assembled it alone and it took a while (1.5 hours with a little break but so be it) it was worth it. :)  The video is helpful along with the instructions. My kitties will want more padding in the little condo spaces, but that is ok - again for the price this is a really nice tree for BIGGER cats as well. Mine are in the 12lb range and just big kitties.  It is really tall so definitely anchor it if you have active cats or more than one.
