My son says the dorm room beds in college are hard as a rock, so last time he came home he tried out his sister's bed with mattress topper and he said it was like sleeping on a cloud compared to his dorm bed.   So I decided to get him this 2in mattress topper, and he says it has transformed his rock hard bed into a comfy cloud bed.  Now instead of tossing and turning he says he's able to fall asleep almost immediately.  No more sleepless nights for this college kid!
