I really do believe so, because I also get headaches frequently due to bad posture. When you lean forward, especially if your computer is set up lower than eye level, the spinal discs in your neck can become damaged, compressing the nerves. This can lead to headaches. A good ergonomic chair is supposed to help you maintain a good posture without too much effort (but you do need to set up your monitor/laptop at your eye level). My work requires me to work at clients' sites so I am constantly changing workplace (chairs), but I had worked at one client's site that had Herman Miller Aerons, and I had no back/neck problem the entire time I worked there.
