Very sturdy chairs that work perfectly for our needs but they do come with some tips

1) attach thinner legs to the baseseat first towards the back, the thicker legs second at the front. The wider part of the seat is the front. 

2) attach everything fairly loosely at first, then snug the screws, and do a final tightening with someone sitting in it. This gets rid of any rocking. Only one of the four we bought sits level, so don’t expect it to be perfect. 

3) we put wood glue on the dowels for the arm rests just to make it a little tighter. 

They really should cost less than 200 each for the hassle, but fit our table really neatly. The wood grain is very cool looking, sturdy build and we know they’ll withstand our kids, family and friends for many years to come. The angle of the backrest is very vertical. If you lean back, you’re contacting the top of the backrest - meaning that you’re going to have perfect posture in this chair. See recommended children’s seating position in photos.
