Add an extra layer of support to the surface of your mattress with the Sleep Master 2″ memory foam topper in queen size. A mattress topper also helps to prolong the life of your mattress. This 2-inch topper is made of our super soft foam that is ventilated in the areas that hit key pressure points on the body – neck and shoulders, hips and feet. Our Sleep Master memory foam is infused with Evergreen and ActivCharcol. Evergreen is a green tea extract that naturally neutralizes odors from day one, while ActivChocoal is made from purified charcoal that absorbs moisture minimizing odor-causing agents. All Sleep Master memory foam mattress toppers are CertiPUR-US certified. Our patented compression technology allows for convenient FedEx/UPS delivery. Once you receive your memory foam topper please allow 48 hours for it to fully expand.
