Purple Restore Plus gives you more targeted support with a zoned responsive coil core, topped with a 3-inch layer of GelFlex Grid and an enhanced breathable foam layer for extra comfort and cooling benefits. Non-toxic materials – Our 100% nontoxic GelFlex Grid material is CleanAir GOLD and CertiPUR-US certified as is our high-density polyurethane foam. The top GOLD rating from Intertek, a third-party quality assurance company, confirms that certified products will reduce health risks related to chemical exposure and meet the standards of other agencies promoting minimal VOC exposure. Purple products won’t produce strong off-gassing; at most, there may be a faint “new mattress smell” at first that comes off as nutty or woodsy but should quickly fade. Certified Clean Air GOLD – Made from hypoallergenic materials that are both CertiPUR-US and Clean Air GOLD certified so you can rest easy knowing you are snoozing safely. Hypoallergenic – A safe option for people with allergies, Purple mattresses are made with recyclable, food-grade and food contact-grade material. Additionally, Purple mattresses facilitate airflow to keep the mattress dry, which helps prevent mold, fungi, and bacteria growth. Made in the USA -Purple’s mattresses are made in the United States using American-made materials with consistent quality control. We also produce our GelFlex Grid in the U.S., using machines we created ourselves.
