On the web site, the sticky says, either 48" x 78" or 84" but in the written description, it says either 6' or 6' 6" long. I am 6' tall. In thinking, it would give alittle more warmth with the fill just a dash more compressed at the 6' length vs. the 6' 6" maybe? And what is the correct length? Does anybody know or understand what I am asking?
