After reading reviews, was prepped for the suggestions. You do need your own tools to make it just way more easier. Have a ratchet hex and drill handy. When doing the stools, put together in diagonals before fully tightening. When doing stool top, keep base still loose to adjust as you go to make sure it doesn't wobble. Otherwise it will. 
Other than that, completely love it! It's exactly what I wanted and fits my space perfectly.
