I WAS SO EXCITED TO GET THIS MATTRESS TOPPER AFTER READING REVIEWS, BUT I  DID NOT FIND IT TO BE COOL AS DESCRIBED, I DIDN'T FIND IT TO BE " GEL" EITHER. THE TOPPER LOOKS AND FEELS LIKE THE BLUE FOAM MATTRESS TOPPER I JUST GAVE AWAY BECAUSE IT WASNT COOLING, AND NEITHER IS THIS ONE.
AS FAR AS THE ODOR IT ISNT BAD AND IM SENSITIVE TO SMELLS, THANKFULLY, AFTER THREE HOURS IT WAS NOT NOTICEABLE AS I THOUGHT IT MIGHT BE.
IT IS VERY SOFT WHICH I AM HAPPY ABOUT DUE TO HAVING FIBROMYALGIA. IT WORKS WELL WITH MY ELECTRIC BASE, INFACT RAISING THE BED COMPLETELY ALLOWS ME TO BE ABLE TO MAKE MY QUEEN SIZE EASIER.
I WOULD HAVE GIVEN A FIVE IF IT WAS GEL AND COOLER.
