Peter,

self inflating mattresses like the Thermrest have foam with a memory inside, the tough outer coat traps the air. Compared to pump up mattresses they are chalk and cheese, the Thermarest will keep you warm on the coldest nights, while the air mattress will leave you shivering.

Chris, is heat loss through convection as bad in self inflating mattresses as 
in the ones you have to pump up? I've never used one, but imagined they had 
some foam built in.
