This is the best cushion there is
I have a problem, my tailbone constantly aches due to the way I sit in desks, and because my school uses 1800's style wood planks for seats.  This cushion solved both of those problems. There is a small cutout at the back where your tailbone fits so that it is suspended. This is great because this way it has no contact with any surface and there is no way for it to get sore. Also, it slopes slightly forward so it really maintains my posture, and also makes me more attentive in class by naturally allowing my body to sit a little more forward. Thanks for the review.
