This is a great product.  I purchased it because I could feel the contours from the tufting of my mattress through my very expensive mattress pad.  I wasn't sure that I would like this topper since I slept best on an extremely firm bed; however, the topper gave a nice, cradling effect without compromising the firm support my body needs.  

Additionally, there was slight odor initially, but that dissipated within a day or two.
