boy I will never complain about those lousey mattresses we run across when traveling in various motels/ hotels... can't imagine sleeping like that.....
just thought of another item to send in next care package, maybe it will make it just a bit more comfy , its the blow up airline pillows.( ours are made by samsonite) ..the ones that are U shaped that your neck fits in ( at least its something) whats nice about those is they deflate and store in small pack and are at least flexible enough to store in their gear bag...and then when they want to use them they just need to blow them up.
