I am not quite yet finding this mattress  to be ALL that comfortable..YET.  Any person needs to give their body time to adjust to a new mattress.  This mattress is much different from my prior pillowtop mattresses I've been used to for the past 20 plus years.  It is growing on me though.   It conforms to your body, it isn't too hot or cold, or too firm or too soft, but it's just different. I know you are given 100 days so we shall see.
