Really works!
At first I couldn't tell the difference right away, it's not until you sit there for hours that you realize, "hey, I don't feel achy, it must be doin something!". I have been getting lower back/sciatica pain ever since I got my new gaming chair. No matter how much I stretched or did yoga poses, the pain always came back. It tightened all the muscles in my back, shoulders, and butt. Ive only had the cushion for 2 days and I've had no tightness since. Though the mat kind of smells, the casing they give you to put over it hides it pretty well. It doesn't come out till the cushion heats up when you've been sitting for well over 5 hours. If you don't have ac, might be a different story.
