I like the temp. somewhere in the middle...I guess what most of you all would consider warm. For sleeping 75-76 is good (while awake, maybe a couple degrees cooler) but any lower than that and I am freezing. My roommate often goes to bed after me and she cranks it down to like 66-68 degrees. I literally wake up in the middle of the night with red nose and cheeks and FREEZING hands and feet (because I leave my ceiling fan on as well). So I get up and put it at 75...lol. I love my roommate but she has no concept of energy conservation...but that's a whole other topic ...
