Sleep Master’s 2″ gel memory foam topper can help protect your mattress or enhance your mattress with an extra layer of comfort. You can easily rejuvenate an existing mattress with our gel-infused memory foam topper. The 2 Inch of gel-infused memory foam helps to provide a cooler sleep versus traditional memory foam. Our 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 foam is CertiPUR-US certified. The cover is not included. Our memory foam topper can fit under any standard fitted sheet or deep-pocket fitted sheets if you have a 14″ or higher profile mattress. Our patented compression technology allows for convenient Fedex/UPS delivery. After removing the product from the packaging, please allow 24-48 hours for the memory foam topper to air and fully expand.
