God bless you for bringing this up, my husband and I sleep alone as he snores so much, it has been that way for years and I am always cold, daylight, midday and nightime, and have finally have my own electric blanket to keep me warm at night, now I wish there was a solution to keeping warm during the daylight hours, I loved hot flashes, and wish I had them more often now..but due to age they are so much more frequent then before. This mattress thing is to be explored whee the heat comes from the bottom...how I love you women who are cold all the time...I think God messed up on this one giving men the warm side of life. Ha.
