My problem with chairs like this, they are designed for leaning back in, even if it's just a little bit. They are great for that, but if you are sitting perfectly upright, your back isn't supported at all. I had to buy a $700 chair (Herman Sayl "gaming edition" with all the adjustable bits) to get one that would tilt *forwards* by just a couple degrees which means I can have it tilted to support my back when I'm sitting upright.
