I agree with the comment from another Amazon, I confirm that the wheels do not turn. This is a real problem for an office chair. The rest, seat, back, comfort, impeccable editing. I have an explanation of this non-issue, this product comes with castors for carpet and not for hard floor. The casters for carpets are unique in that crash if there is no load on the chair and when there is the human load, the wheels run on the carpet. So I put a rug on my hard floor and there, no problem. For hard ground, take castors for hard floor and not carpet. That, Sincerely.
