I received the mattress that I linked to in my above post and finally slept on it last night. I’m really impressed! I was expecting it to be more like an air mattress but really it is just a 4″ dense foam in an airtight sleeve. Last night it was just below freezing here and the mattress helped keep me warm as well as being very comfortable. Usually I can’t sleep in while I’m camping but I didn’t wake up until 9AM. My wife liked it as well.
Here’s a photo my wife took:
