For anybody above say 60 years of age or anybody with lower back issues this product is an absolute must. It does everything the manufacturers tell you and more...! I suffer from chronic back pain and since I put it on my car seat the results have been wonderful. I would not remove it for the world! I suggest that this cushion could (and probably should) be used by anybody as a preventive measure especially if you do a lot of driving. It is also very comfortable.
