Who has a booster seat cushion they like?

Does anyone use a wedge or other type of cushion that fits well in the car?

I am in need of a driver's booster seat. In my first cursory googling for this product, it looks like a lot of the ergonomic cushion type products would not fit well in the bucket seat. Maybe I'm wrong about that.

(I am very short in the torso, and I need to raise myself up relative to the seat back. The proportions are off and my shoulders don't reach the part of the seat designed to accommodate shoulders, etc. Long drives have become painful and take days to recover from!)

Thanks for any input!

 

thank you @sam spade 2 and @tchan2700 !
