I am very happy with this cat tree. It actually is quite easy to put together. When I made a mistake early on, it became obvious and was simple to fix. [...]. I was happy with  the price compared to comparable cat trees in pet stores. It does wobble a bit but  it doesn't seem to be a problem. To my surprise, my younger cat isn't using it and he was the one I had in mind for it. I think the older cat (2 years) just took it over and made sure he stayed off! But the older cat loves it. He's now the king of the castle. And even though I might have liked the upper seats to be bigger, he seems fine with it. A very good experience, all in all.
