Nitrile is a puncture resistant type of rubber, used in gloves to stop
needle stick injury.
So why not use it making an ultra rugged self-inflating air mattress?

I've looked into this whole puncture resistant material thing a while ago.
Nitrile is a fairly old invention (German Buna-N). The nitrile gloves
that are fairly puncture resistant (for handling roses) are very thick and
a mattress made of them would be heavy.
A tightly woven nylon provides some puncture resistance. This is what the
Therm-a-rest people seem to use. The market for puncture resistant
materials is quite tight, especially if you want flexibility and a low
weight.

Ortleib - a German company - make puncture resistant self-inflating
mats.

Air mattresses of any material are poor insulators.
For serious outdoors use, especially in cooler weather, the best
choices are either a closed cell foam pad (usually EVA), or one of the
"self-inflating" pads, with open cell foam inside an airtight nylon
shell.
Also, puncture resistant is not the same as abrasion resistant.
Happy trails,
