Except that after sitting with it for 40-50 minutes, it flattens out a lot. I just wish it was a little firmer.I should add, it has so far regained its shape when I stop using it. I've only had it for about a month, so don't know how long that would last.Also, it's hard to use this with leather seats in a car. Even though my car seat does have its own lumbar support, it's not good enough for my taste.As a concept of lumbar support, I am a true believer. This is the first product I have tried, and I am not perfectly satisfied with it. But I prefer having this, than not having anything. I will keep looking, and if I find anything better I will come back and report here.
