We've been living with 3 of these stools for over a month now and are very pleased.  The assembly just took a little time but was fairly straightforward.  I've seen posts about how one of the 3 seat screws goes through the frame but misses the seat; this is somewhat true.  However, in my view, only the screw in front (which always hits its mark in the seat) is really necessary.  It seems that 1 of the side screws misses on each seat, but it's practically superfluous.  The seat rests inside the frame and can't shift around, and it isn't going to jump out, so the front screw does all that is required.  The quality is very high and they are very comfortable.  No complaints.
