This is a question that has been asked one million times, so forgive me, I'm asking only for the first time. Has anyone ever come up with a nice way to supplement the driver's ( and passenger, too) seat bottom cushion? I think now and then that there must be a high-tech or even low-tech foam or material that could be fitted on top of the foam but under the seatcover. I mean with all the new materials used today, like my bed at home is such a far cry from when I grew up ( with 2 brothers in mine!!). I am almost ready to put backt he seats and my wife especially, would love an improvement to the seat cushion.
