This topper is absolutely comfortable. The density is just right and it fits my matress perfectly. There are no bad odors when I opened it and none of those chemical smell that came with some of the toppers I tried before. The thickness is perfect. It supports my body well when I sleep and I wake up feeling well-rested. It is good for my back too because I noticed I dont have back pains anymore since I used it. Definetely a good buy.
