Has anyone used it in combination with the ComfiLife bottom seat cushion?

Yes, and I concur with Dympo. The combination of the two has made a world of difference.

is it too thick for the car

Yes, it is too thick for my Nissan Altima. I moved my seat back two inches, and the cushion still binds/slips towards the passenger seat when I slide into the driver's seat. Once seated. it felt like my stomach was being pushed out, rather than my back supported. Tried it in my wife's M-Class MB and it was even worse...if it was half as thick, it might work in a car

Is the 15 inch dimension the width or height?

it's 15 inches wide and 12 high. and I love it!

If choosing only one, should I get the seat cushion or the back pillow?

Seat cushion. Excellent product.
