    What is a Mattress Topper?

    For beds that have lost some of their firmness or maybe just need a little extra padding, a Serta Memory Foam Mattress Topper can give your bed the added comfort your body needs. A mattress topper is a removable piece that fits squarely on top of your mattress based on its specific size. It is designed to give your mattress a level of comfort that it cannot provide on its own. Typically mattress toppers offer supplemental support to a mattress that is either too soft or is simply past its prime and has lost much of the support that it could provide when it was brand new. In addition to supplemental support, quality mattress toppers can also provide a unique softness that you just can't get from a traditional mattress pad.
