If the office chair you buy ends up not being the most comfortable, there are ways to fix that. For example, you can buy an office chair seat cushion to add more support and comfort. There are all different types of seat cushions that will fit any chair. In addition, you can add a lumbar support pillow to your office chair if it is lacking in that area. There are actually lumbar support pillows specifically made for office chairs, so you'll have plenty to choose from.
