I use to use the roll but this is better. It stays in place, its firmer, and feels better on my back. I only use this in the car and that's where it fits right. I wouldn't get too use to these or you can't sit without them. Remember they are for support, like a crutch. If you use them all the time you will have a weaker core to support yourself. I use them for unnaturally long trips.
