Like many others, it seems like I've been on a lifetime journey to find comfortable sheets. I live in Arizona, so cool sheets feel like a necessity to me. I was on the brink of ordering a very expensive set of bamboo sheets from a speciality site, when I saw the reviews for this set on Amazon. I'm so happy to report that these sheets are exactly what they purport to be. They are EXTREMELY comfortable and soft. They are also very cool. My husband doesn't believe in "cool" sheets because he sleeps very hot - he wakes up sweaty more often that not, usually - but he exclaimed last night that these sheets are very cool. He has not complained of sweating at all since we switched to these sheets, 2 weeks ago.
