I am so satisfied with my new topper before I had the 4 in and it was hard for me to sleep on my stomach. Now I can sleep on my stomach due to the firmness of the 2 in. My sheets also fit my matress better they no longer come off the corners. For those who like to sleep flat but comfy the 2 in mattress topper is a great solution. I will purchase another after this one wears out.
