Easy to assemble. Bolts aligned well with pre-drilled holes, with a couple exceptions. Purchased 2 sets, each set had 1 stool that wobbles - trying to figure out the best aesthetically pleasing solution. 

Due to the height of the back, the top of the back touches counter top. Our counter is granite, so when the back meets the counter - it's a fairly loud noise. Only a problem when you have 2 toddler boys climbing on them. Otherwise, no issue when adults are using.
