I bought and used this to help with lower back and back pain while driving. It's made with a pressure-redistributing gel recognized in the medical and welfare fields, making long drives comfortable. It's divided into three sections for the back, lower back, and seat, each with Velcro for fine-tuning adjustments. There are a few wrinkles, but it's relatively clean with no stains. It also has adjusters to secure it to the headrest. And since it's gel, it doesn't sag. Also, because it's divided into three sections, it can be used on wheelchairs, using just the backrest or seat section, etc.
