But on the third hand most people don't stand around on stairs so a
thinner but higher density underlay (eg 9mm) may give the same
protection as a thicker but softer one (eg 12mm) more suitable for
other areas.

On the 4th hand neither will offer the carpet much protection against
wear.

Problem I've found is the standard 'free' underlay pretty soon loses any
effectiveness where it is heavily loaded - like the edge of the stairs. So
doesn't make much difference how thick it was to start with. It's often
just a pile of dust after a few years. Unlike Cloud 9. Of course if you
change the carpet anyway every few years this is unlikely to matter.
