I wrote a praising review before I had really experienced this mattress. Now after a few months, I know that if I could do it again, I WOULD NOT. I thought it was the sheet/cover set I bought that was making me sweat and so I replaced it all with organic cotton (sheets, mattress pad and comforter) but even after making that expense I am still waking up sweating like a pig, drenched in sweat. Do not buy this mattress would be my only advice. It is a very expensive mistake I have made. I like the "feel" of the bed, but if you're dying of heat stroke, what does that matter in the end? The only thing that mitigates this heat thing is for me to climb out of all my covers in the middle of the night, switch to the other side of the bed, and sleep ON TOP of my comforter, which then takes away the feel of the bed, and then I wake up with a crick in my neck. If I could get my money back and buy a regular mattress I would. If anyone has suggestions to make this bed work for me, I would take them. Like I said, I feel like I've tried everything and thrown money after money on this one.
