Love this . No odor on queen size however I ordered another in full size but has an odor. I am currently airing it out before putting on my guest room bed. My queen mattress  is getting old and didn’t want to spend the money for a new one co I ordered the queen topper. Couldn’t be happier with it. Not too soft. Just right for my husband and I. Love the pillow top cover  fits easily over my very deep mattress .
