Can't drive without this.
I have extensive spine arthritis and these pillows (which you just partially inflate) give me the perfect support in whatever area that is needed that day.  I have used these for years and it is true that sometimes they can fail quickly (perhaps in part due to being left in a hot or cold car), but others have lasted years.  I always keep a spare in car and take one when I travel for other cars.
