There are those who have old and even damaged mattresses with the springs almost coming apart, but one may not necessarily have to buy a new bed as long as one utilizes a thicker foam mattress topper. In fact, there are even those who prefer to layer extra thick memory foam pads on top of a box spring, forming their own custom memory foam bed topper that provides a luxurious feeling. Many people who become accustomed to sleeping on foam mattress toppers will find that when they sleep in another bed, such as in a hotel or on vacation, they truly miss the comfort of the memory foam and have trouble sleeping without it.
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.
