I broke down and bought the dura foam replacement driver's side seat cushion.

I must say the first impression is pretty good.

Plenty of support, and I don't feel like the seat sags in the behind anymore.

That being said, the directions are a hot mess.

It wasn't difficult to figure out.

Removing the seat from the truck is the best way to go.

Find some pliers that will make it easy to squeeze the seam clips together.

It was a PITA with needle nose Pliers.

All in all well worth the money to switch out the seat foam.
