Product purchased to soften a little too firm mattress. After a week of use, no miracle, a very slight sensation of sweetness, a little wrap-side, but nothing transcendent. I always feel the firmness of the mattress. A large quilt topper more than it seems. Nothing to report at this time sweating side, I quickly warm at night and I was afraid that this mattress topper is not breathing. Finally he did better than my next breath mattress. We find the sleep quality. I'm a little disappointed brought comfort but if you know what to expect, it remains a correct product (especially on special).
