Not for in car use
I didn't notice much cushioning at all. On a 360 mile trip in my vehicle, I had to stop using the Simply Purple seat cushion because my butt got numb. It also is too small. The cushion ends about three quarters of the way down the back of my thigh and that bothers me. It also tends to move on the seat.<br />One other thing that makes it poor for use in a vehicle is the fat that you cannot leave it in the car. The cushion will melt at 105 degrees. I didn't try it. That is stated in the instructions. The interior of a car gets hotter than that if parked in the sun. And the cushion is heavy to carry around.
