I waited a few days before writing my review because I wanted to sleep on it a few days to really see what it was like.  When the topper came, I unpacked it and laid it out flat.  There was no smell at all and I expected one.  The first night I put it on the bed, I really didn't notice a difference.  Second night was better and by the third night when I hit that bed I felt like I melted.  It is so beyond comfortable!  I am so pleased with it and would recommend it to anyone looking for a great topper at an even greater price!
