It's not the bottom cushion that's the problem but instead it's the back
that's holding itself stiff enough.

a cheap and easy experiment is to cut blocks of flexible foam and slide
them inside the springs of the seat . You can adjust the give of the seat
with the height of the block . I'd also put stiffer ones in the springs
next to the door. The passengers always think they are going to be flung
out of the car if that side is soft. What can I say worked for me, Mike
