can someone help me find a good sleeping pad/mat?
i am going on a camping trip for a week and i will need a sleeping pad.
ive heard therm-a-rest are good.
im a bit of a diva when it comes to my sleep and i like to be comfy (the thicker the better) although i need to keep it small because im sharing a tent with 2 other people.
can any one help?

Aerobed makes a good inflatable mattress.
