These stools look very nice, however there are areas for improvement.  Unfortunately the cross section on the bottom for additional support doesn't stay connected despite the screw, leaving an area that is exposed wood, and has less support.  I will attempt to fix this with gorilla glue, however for there price, I would expect this to be better designed so the cross section could just stay connected with the screw.  I don't know how well these will hold up, but my children predominately use them, so hopefully I will get some time out of them.
