The product had to air for several days to lose a very unpleasant odor (mix between synthetic material and mold).  This is not cooling at all. We purchased this topper with the hope it would help us cool down a very warm foam mattress (described as a “cooling topper”).  This topper makes the bed even warmer, which contradicts the specifications listed by Wayfair. It makes it impossible to sleep.  It’s also too plushy (everywhere, despite the “zones”).  Quite disappointing. Not recommended at all. Quality doesn’t seem very good either. Terrible purchase. I hope i can return it.
