Memory foam is most commonly made from polyurethane and various gel materials, according to Dr. Holliday-Bell. However, not all memory foam mattress toppers are created equal. Below, you will find the aspects recommended by experts to consider when selecting the best mattress topper:
✔️ Certificates. Certificates of CertiPUR-USwhich only certifies polyurethane foam, will help ensure that your mattress topper does not contain harmful materials such as flame retardants, heavy metals or formaldehyde.
✔️ Density. If you are concerned about body aches, a higher density mattress topper would be the right choice for you. “Higher density foam will provide more support and durability,” as well as help with motion transfer isolation, Harris says. However, low-density foam is often better suited to warm sleepers, according to Dr. Holliday-Bell.
✔️ Thickness. Toppers typically range from one to four inches, notes Dr. Holliday-Bell. She suggests looking for a thicker topper if you need a big change in the feel of your mattress, and a thinner topper if you’re just trying to add a little extra softness. Toppers on the thinner side are great budget-friendly options and are generally easier to fit over under-fitted mattresses and sheets. However, thicker mattress toppers tend to relieve pressure more, Harris says.
✔️ Care. Many mattress toppers need to be spot cleaned as most aren’t machine washable, and those that are can be cumbersome to load in the washing machine and dryer. According to our experts, a removable and washable cover is often a practical thing to look for.
