Dunno but generally speaking with stairs the thicker the underlay the

On flat surfaces (rooms/halls) I've always gone for Cloud 9 either 9 or
11mm thick. I agree a thick underlay may be more difficult on stairs and
maybe a thinner underlay could be used in this one position.

Except, of course, the edge of a step is where a carpet gets the most wear.


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.
