The instructions could have been better.  I used the photo on the box more than those!  My cats haven't used it yet, but are curious about it.  It is pleasing to look at and will be staying outside on the porch for others to see.  You can put it together any configuration you would like.  They just don't recommend all in one stack.  It would fall over.  The main reason I bought this was because it can be outside unlike the pressed wood ones.  And another benefit: you can take it apart and was the fabrics!
