Ordered the 3 inch topper and it unfolded nicely and fit perfectly on our full bed. No odor to deal with which made me happy. It did not arrive with the cover it said it came with, so disappointed. We haven’t slept on it bc it’s for our son’s dorm bed but it appears that it will add the cushion needed for a better nights sleep.
We ordered the 3” queen for our camping trailer. The original mattresses are very thin so having this helped a lot, especially since I’m pregnant and we were sleeping on it for nearly two weeks. 4 stars instead of 5 because there was no noticeable cooling effect. We are both hot bodies and there was no difference between this and a normal mattress. But besides that it’s great!
