I recently saw a driver with a arm cushion that went on the drivers door, and a really nice seat cushion that inflated, vibrated, etc. It looked like it came in a set.
Does anyone know where I can get one of these?

The arm pads can be found at most truck stops. I have seen them at many Pilots, T/A's, Petro, Flying J. You can get them in various thicknesses, colors and in vinyl or cloth. Every truck stop may not carry a wide variety of them.

I think the seat cushion you are talking about is called the Air Hawk. The truck stop is used to see them the most at were TA's and if I recall right they are a bit pricey at around $100.
