I have NEVER written an online review, but thought this one was necessary. I bought two sets of these barstools. One of the four had problems...I couldn’t lower it to the lowest position (which was needed for my counter). I requested a replacement and it was on my doorstep in two days!! The new set (yes - a pair even though only ONE chair didn’t work) was perfect! I even decided to order another set for a different location in my house since I loved them so much and knew that any problems would be taken care of immediately. Love this product! Highly recommended!!!
