Mattress toppers are made to be placed on top of your existing mattress. The foam molds to your body, supporting all parts of it equally, so there are no pressure points to cause pain and soreness. Memory foam mattress toppers are a great way to give life to an older bed. Look below to learn answers to the most frequently asked questions about memory foam mattress toppers.
What should I know about purity?
Choose a memory foam mattress topper that is made of pure, high-quality memory foam. Some manufacturers use filler to pad the foam. This creates a lower quality mattress topper that will break down quickly. Choose a memory foam mattress topper that promises to have 100 percent pure memory foam.
What density characteristics should I look for?
Purchase a mattress topper that has high-density foam. The higher the density, the better the foam will support your body. Anything over a 5-pound density is considered high quality.
What thickness is best?
Select a memory foam mattress topper that is thick enough to provide plenty of comfort. Three inches is considered perfect for average-sized people, although you can purchase foam mattress toppers up to 4 or 5 inches thick if you feel you need the extra support.
What should I know about firmness?
Memory foam mattress toppers are given a number that represents how firm they are. This number is different from the density rating. The softest toppers have the lowest numbers, and the firmest can reach a rating of 20. Most people prefer a medium-softness ranking of about 12.
How does sizing work?
Check to see how large your memory foam mattress topper is. Some manufacturers cut costs by making the toppers slightly smaller than the size of mattress. A topper that is advertised as "queen size" may be a few inches shorter than your queen mattress. Check to see if the measurements are listed to be sure it will cover your mattress completely.
