This is something I should probably know about by now, but sadly enough I do not. I hear some of you guys discuss this term when comparing mats, but you never go into details about its meaning because both parties always know what the other is talking about. I tried doing a search on it too, but did not see any posts that were directed at what it is, at least not on the first page of entries that I were sent back to me.
Therefore, can anyone tell what R-Value is when pertaining to air mattresses, why it is important, and how to tell a good R-Value from a bad one? Thanks.
