Air bed for side sleepers?

[The Cameraman]

Hi Guys n Gals,

for years I've been using Therm-a-rest, self inflating air mattresses, whilst camping and, to be honest, I don't really get a proper nights kip.

The problem I have is that I naturally sleep on my side but when camping I find I get very little support, so end up on my back and wake up the whole camping site (including myself), with my snoring!

So this maybe like the hunt for the holy grail but this is what I want;

1, good support when lay on my side.
2, light enough to carry on a small motorcycle.
3, small packed size, to carry on a small motorcycle.
4, I'm only 5ft 4in (on a good day), so I don't need something for more lofty folk.
5, a surface that resists you from sliding off during the night.

So come on, some one, somewhere must have discovered the perfect option?

Regards

Reggie
