An investment in a good night's sleep, a memory foam mattress topper is made to mold to your individual shape, support every part of your body, and cut down on painful pressure points that can develop when you're not properly supported during sleep. Mattress toppers also add a bit more padding to your standard mattress, making your bed even more relaxing. Here's how to choose the best one for you.
Compare the prices. When it comes to memory foam mattress toppers, it is true that you get what you pay for. More expensive toppers are likely made of pure memory foam and will not contain fillers, which can rapidly break down. One of the defining characteristics of high-quality memory foam mattress toppers is their ability to slowly spring back after being pressed. Those that hold an indentation well for long periods of time contain the most memory foam.
Compare the density ratings. Memory foam mattress toppers are given a density rating in pounds. A higher rating means the memory foam will remember your shape better and last longer without sagging. The ratings can range from less than 3 pounds to more than 5 pounds. Some sleepers prefer a lower density rating, especially if they sleep on their sides and want a softer sleeping surface. A higher density rating means the topper is more durable, and it will give a firmer sleeping surface, too.
Compare sizes. Some memory foam mattress toppers are not made to completely cover a large mattress, leaving inches of space around the edges. Measure your mattress to ensure that you find the memory foam mattress pad that suits you best. It also helps to compare thickness when shopping for a memory foam mattress topper. For light support, look for one that is 1 to 2 inches thick. For substantial support, you want your memory foam to be at least 3 inches thick.
Compare firmness. The firmness number indicates how soft or hard the foam feels on your body. A number between 15 and 20 means the mattress topper is very firm, and a number below eight means it is quite soft. Most people prefer a firmness of around 12. To decide which firmness is right for you, think about how firm you want your mattress to ultimately be. If your mattress is firm and you want to add a bit of softness, choose a low-number mattress topper.
