There are so many things to love about this cat condo. The quality is excellent and great care was taken in packaging. There were corner protectors on the large pieces to protect them from damage and all the small items were in sealed bags. Every piece and bag was labeled to make for easy assembly. I did have a problem with 8 of the directions and attaching the holder for the bowls. It appeared that the holes were to the outside of the support but needed to attach to the inside. I just removed the piece and turned it and all was good. 
Another attention to detail I appreciated was that every pack of screws etc had an extra piece. How nice to have more than needed rather than less. 
This is a very sturdy well thought out piece and I highly recommend it.
