Foam: By far the most popular fill for mattress toppers, foam is a great option if you’re looking for extra plushness and a bit of support. Soft and comfortable, foam toppers relieve pressure and come in a range of thicknesses. They can get hot, though, so if you’re a hot sleeper, you should look for gel-infused foam.

To avoid making your topper dirty, make sure place you store it is clean and dry. If the room or closet is damp, this may lead to mold or mildew forming on the mattress topper. Likewise, make sure the storage place is temperature controlled, as a room that's too hot or in direct sunlight may damage the foam.
