"After spending some time in the Flash XL, it becomes clear that a good chair is important, especially if you spend much time on your computer. The Flash XL, like the Champion, is whisper quiet. I could shift my weight from side to side, forward and back, and move all around and not hear any sounds. For me, that is a big plus. I can't stand a noisy chair. I can say that once you use a chair like this, there is no going back. And again, as I experienced with the Champion, the quality and workmanship on the Flash XL are excellent."
