Yes, that really is a great cushion. BUT, this doesn't work on every car. If your vehicle has lumbar support and/or heated seats. leather seats. Strange "fancy" seat covers. Then it might not work for you. My husband's truck has all of these things. Well, technically, he's mine now that he's dead. In any case. I thought maybe a truck would be more convenient, but that turned out to be impossible. I couldn't lower the seat far enough. I couldn't get comfortable. It was so bad that I had to pull it from under me while driving. I couldn't stop because there were many cars behind me. This pillow has now become the pillow on my work chair. Basically, since I work from home and spend a lot of time at my desk, I'm always looking for a way to make work more comfortable. This is absolutely the best solution I've found for this in over 3 years. So while it didn't work out as originally intended, it worked really well for something else, and I have a feeling it's even better.
