The top of queen size mattress pad is wonderful - which is why I'm keeping it - especially for the great price.   But...the fitted part to pull over queen mattress was not for a queen.   It would not fit around a queen mattress at all.   The top would not lay flat either until I just went ahead and broke the elastic around the bottom.   So I'm using with an older mattress pad over the new topper to keep it in place.    I believe the fitted part was more for a double size mattress, not a queen.
