Slab Rubber

For more luxury and long wear one could use 100 ounce 19lb density slab rubber padding. Unlike the waffle rubber padding, slab rubber does not contain big ripples of air. This pad feels much like 8lb rebond, and does  resist furniture indentation and crushing for a  long period of time.  I recommend this pad for the highest of traffic areas like stairs, but only if you plan to be in the home longer than 20 years using the same carpet.  Froth foam would be a better alternative for the cost.
