Overall, I'm happy with this cat tower - both our cats certainly enjoy it (10 and 11 lbs).  One issue was that a corner of one of the platforms arrived broken. However, it's sandwiched and nailed between other parts so that is what is keeping it together. The fabric could be thicker or sturdier especially because there are a few small areas that seem sharp with only the thin fabric to protect cats from it. None of these things have been causing any problems for now though. I just think it should be known. Otherwise, I really like the design -  I like that it sort of resembles a bookshelf. It has nice modern lines and we chose the beige one which of course easily matches many spaces.  More importantly though, our cats love to: sleep at the top, chill in the condos, and especially enjoy lounging at the top and looking down at everything.
