I'm really good at putting together furniture as long as there are a few instructions.  Instructions for these stools were not super clear, but I managed just fine.  My issue is that the piece that you sit on (where your butt is) does not have pre-drilled holes for the screws.  As a result, both of my seats are a little crooked, I tried everything to get them to be centered, but it was hard to line up and see from the bottom (where you drill the screws in).    

Pros: cheap, sturdy
Cons: no pre-drilled holes for the seat piece
