We purchased a memory foam mattress a year ago and found it too firm to be comfortable for us. This mattress topper is absolutely wonderful. Our bed is so soft, you honestly feel like you're sleeping on a cloud, yet it is supportive. I sleep through the night and wake refreshed, no more waking up with a sore back or aching hip. I plan to purchase another Slumber Solutions topper for our camper. Contrary to the reviews I did not notice any horrible smell and the topper fit our queen size mattress perfectly.
