Mornin!
We have an air mattress. When I was expecting Bittygirl, and could no longer tolerate our regular mattress, I slept on the air mattress. I figured out that in order to not sweat or freeze I had to either wrap myself in the blanket/covers or sleep on top of a blanket. I.E. have the blanket or some covers between me and the mattress to form a blanket sandwich, so to speak.
Speaking of air mattress...Jr. lost the power cord to the pump on his Aerobed.
Note to self: Gotta get him a new one before choir tour.
