Like most toppers/bedding products these days, this topper came compressed.  After "airing up" for about two weeks, it is still only 2" deep, at best...a full inch + shy of what is advertised.  Additionally, the topper material is cool to the initial touch, however, within two minutes of laying on it, it is just as hot as the mattress would be without the topper.  Very disappointed with this product, considering both selling features--the 3" depth and the cooling--are not really true.
