Replacing your mattress can be very expensive, so a mattress topper is a great way to revitalize or change the style of your bed instead. With some careful research, the right one will give you what you need at a fraction of the cost of a brand new mattress. A mattress topper will usually add a more significant layer of softness, cushioning or support for your body. You can even use both at the same time to further improve the quality of your bed. By placing a mattress pad over the topper, you can help protect both the topper and the mattress.
