The Serta 4 Inch Pillow-Top Memory Foam Topper is a rectangular mattress pad that adds a layer of memory foam with a pillow-top finish to a twin bed. Its 4-inch profile is thicker than most toppers, which makes it a fit for softening a firm mattress or adding cushioning to an older one. It suits renters, guest beds and sleepers who want more pressure relief without replacing the mattress. Against thinner 2 to 3 inch toppers it offers more sink-in comfort, but it adds height that can affect sheet fit and it sleeps warmer than a latex or gel topper.
