I have a long torso. On a non-rotating office chair cushion is good. My BMW car Komforsitz is set at the lowest level and my head almost errreicht the roof. Now comes the rotation cushion in between there is scarce. Therefore, I take the pillow only at short distances for shopping. Since it is a good help. In long-haul the pillow behind the driver's seat. The cushion is only one exit aid but which significantly reduces the seating comfort. On the purchase of a second cushion for the passenger seat, I was planning actually I renounce. My wife removed the same size pillow immediately when she drives.
