A mattress topper adds a soft layer on top of a bed you already own. Memory foam toppers contour to the body and usually come compressed in a box. They suit a bed that feels too firm, a guest bed or a worn surface, but they will not fix a sagging mattress.
The six toppers below are all queen size and 3 inches thick. Firmness, weight, covers and certifications come from each product’s listing page. We have not slept on these toppers ourselves, and we make no health claims. Some listings leave out weight or firmness, noted below.
