Latex mattress toppers might not be as common as memory foam, but they offer a lot of advantages. If you like the support of memory foam but don't like how hot it sleeps, latex is an ideal alternative since it is heat-neutral. Since most latex is plant-derived, you also have the option of buying natural, instead of synthetic, materials unlike with foam and down alternatives. The best latex mattress toppers can do everything from adding a bit more support to rescuing an otherwise uncomfortable mattress.
Instead, the biggest differences come in mattress thickness and firmness. Even a soft latex topper is fairly supportive, however, and is a good choice for first-time purchasers. Thickness, on the other hand, depends heavily on the state of your current mattress. A 1-inch latex topper adds a bit more support while still allowing the mattress's existing support to be felt, whereas a 3-inch latex topper can go a long way in rescuing an old, uncomfortable mattress and can be considered close to a mattress makeover. Since your mattress’s biggest environmental impact happens after you throw it away, a latex topper is also a green purchase if it allows you to extend the life of your current mattress.
The only drawback is that less than 1 percent of adults in the U.S. have a latex allergy and therefore, they're not hypoallergenic. If you or a family member is one of the, however, there is a rubber-free, hypoallergenic pick as well.
