Lowes sells foam matting by the yard, about $6 a ft approx 38 wide, 3/8 thick... I used it in all my storage compartments, step for the entry way, cup holders, door compartments, and for a hallway covering that we put a runner on. Can be cut to desired size.  Helps with noise and gives a good coushining.

Yep!  We use the foam drawer & cabinet liners as shown here yielding the same "quiet" results.  As you can see in the picture, paper towels in-between pots and such also helps.


But for the outdoor storage compartment and entry step, we use carpet runner material sold by the foot.  Just slip out and shake off the dirt.
