Absolutely terrible chair! Cheaply made the seat is too short the back extend your arch in a painful manner and there is no headrest even though the seat extends to the height. Just an overall poor design and a cheap chair do not waste your money spend a little more and be comfortable with your investment.
My old chair failed at holding it's vertical position with gravity soon bringing it to its lowest extreme. This new chair holds its position well defying gravity's want to bring it down. Nice chair.
I bought this chair for my son in May of 2019. The stem broke at the bottom of the chair by December of 2019. Really? He is in college and needed a desk chair. He didn't put undue stress on it. When we turned the chair over to see what had happened a metal piece had broken.
