This has been really helpful in alleviating some of my discomfort sitting at my regular chairs, but even though I ordered the extra firm, it doesn’t seem firm enough to fully counter my weight. It’s great at the dining table where the chair is flat square, but it isn’t working as well for my computer chair, and that’s where I really feel I could use more help. But overall glad I got this because it’s much better than what I was using before.
