These stools are great.  I saw earlier complaints about them falling apart the first usage.  There is one possibility.  Some of the leg screws are easily cross threaded.  They could have felt tight and still be loose.  Otherwise, I have found them to be very solid thus far.  I am a large person and if they were poorly made, I would know it.  Now it remains to be seen how they hold up in the long run.  Good produce so far.
