Helps the back
I'd purchased this for my Dad who was finding sitting uncomfortable. When he no longer needed it, I took it back. I used it on a long car trip and continue to use it in my office. I find that it has truly helped my back and even the nerves to my legs. I'd have never purchased it for myself, but for Dad I was hopeful it would help and it did. I've continued to share it with others in hopes of helping them...
