If I winter camped here in MN, I might try one. As it is, I can't see
using one above about 20 to 30 F. Weather that is my absolute limit
for camping and then only by accident.

One moves. This moves the air in the mattress. The cold air at the
bottom and sides moves to where it can touch the bag. They're really
not enough (though some) warmer than the ground beneath them or the
air around them. When I use open cell foam (car camping) or an air
mattress, I use the Thermarest type or a double piece of fleece fabric
between them and my bag unless it's extremely hot out. They are
nicely comfortable, though. I under inflate them so that I'll sink
right in.

I think there's something missing from this picture. Though usually by
inflatable
one means the inflatable insulated pads even a plain uninsulated air
mattress
shouldn't "cause" hypothermia if the hunter had a proper bag. Air does
provide
some insulation.

Of course it's the cold weather that "causes" hypothermia, not the air
matterss, but I know from experience that a good functional old
fashioned air matterss is very cold on frozen ground. The sleeping bag
is compressed under you, and the air is precious little insulation. On
the other hand, therma-rest is as warm and comfy as it gets. The
camp-rest version at 2 inches thick is a delight even on gravel.

A sleeping bag. Make that a sleeping bag with below zero degrees Celsius
comfort temperature.
A bottom sheet.
An inflatable sleeping mattress.
Waders. Breathables, since we will be hiking to some extent.

I just have to ask, why have an inflatable mattress if you are preparing
for
cold weather? I went late season elk hunting with about 18" of snow, and
that night one of our hunters got hypothermia because he was sleeping on
an
inflatable mattress. The physician in the group had to drive him into
Pendleton. That mattress allowed the cold to penetrate from the side of
the
mattress, where those with the old foam standbys were toasty warm.

Just curious.

Well, that might be so but we're not camping under winter conditions, more
like summer.
It might get down to a couple of degrees above freezing for an hour or two
if it gets realy cold at night.
On the other hand it might be 30 degrees Celsius during daytime, which in my
experience won't in any way mean that you go to bed in cold sleeping gear.

Highly unlikely to get hypothermia at those temps if one is actually
in the sleeping bag, rather than lying on top of it on a very warm
evening that turns into a chilly night. The worst temps bags I've
seen should be safe (if not comfy) at 40 F (about 3 or 4 C?), unless
the user has impaired circulation or an ethanol overload or gets wet
and doesn't dry off before getting in the bag.
