One of my chairs went together with ease while the other one did not fit together at the stable bar.  The hole was not big enough for the pin to fit in and could not be made to fit by tightening the screw.  My friend had to shave out the hole a bit to make it fit.  Unfortunately, during the assembly and trying to get it to fit, some of the paint was chipped.  However, once together, chairs are fairly sturdy and work well at my high dining table.

Pros: affordable, good stabilty
Cons: parts did not fit together without alterations
