seat cushions; I need a better one

[gbraden]

I have a HO 2003 QC, 6 sp. , SLT, the premium seats (fabric, not leather), and so on.

I can drive for no more than an hour before my hip and knee start hurting (pressure on sciatica nerve). Ever since purchasing this truck, which I otherwise dearly love, I have found the seat to be uncomfortable. Does anyone know of a particular seat cushion that might help the situation?

Hope you can help me out on this.

Thanks,

Glenn
