In simple terms, a foam mattress topper is a thick, dense foam that you put on top of your mattress to make you feel more comfortable when you sleep. This is supposed to help you relax by allowing you to be comfortable no matter what your position is when you sleep. Basically, a foam mattress pad hugs and fits your body contours, making you feel better and more supported when you lay on your bed.
This certainly isn’t likely to be true, as Tempur Pedic mattresses are considered by most to be superior to any other models out there. The question is, what do we know for sure about memory foam that can help us get a better night’s sleep? What we do know for sure is that it does reduce pressure points by conforming to the body. This is strictly unique to memory foam, there is no other material that can do this. This feature is possible because the open cells fully compress when you lie down on them, and the air pressure is released to other cells. Therefore, we have air pressure that is distributed throughout the mattress. This is why you don’t feel as much pressure while lying down compared to an innerspring mattress. It also explains how memory foam can contour to the shape of your body.
