Previously, we purchased 4 of these stools and recently added 2 more when we increased the size of our island counter.  A deisgn flaw from the previous stools (rail would roll under feet and presented hazzard for children attempting to stand on the rail) has been corrected with the newer model.  The rails are now secured with a screw and do not roll if one attempts to push up with feet on the rail.  Thus, we are delighted with the counter stools function and appearance.
