I should have followed my instinct and returned these when i received them.  I never complain,  but these  are the worst stools i have ever had.  from day one they squeaked almost like a bird chirp, not constantly but on and off quite annoying.  The ones these replaced were 4 years old, and these look much lder already after only 9 months !!  They are kind of uncomfortabe also , feel like i am slipping forward in the seat. 
the surface stained really easy . Both of them has had missing screws 2 times already in the 9 months i had them . after 9 months they look 5 years old and time for replacement. just cant believe it .  :(   
If i could still get my refund i would without a doubt
