Novaform Advanced Cooling Gel Memory Foam Mattress Topper review

The Advanced Cooling model is the topper to pick at Costco if heat is the main complaint about your bed. Novaform coats the 3-inch gel memory foam with phase change material under what it calls the PerfectTemp system, and wraps it in a cool-touch, moisture-wicking stretch cover. As with the ComfortLuxe Plus, the cover is washable and fits mattresses up to 17 inches deep, the foam is CertiPUR-US certified and made in the USA, and the topper carries a 10-year limited warranty. The queen measures 80 by 60 by 3 inches and weighs 28.7 lbs. Costco listed it at $169.99 for a queen on November 11, 2026, $10 more than the ComfortLuxe Plus. It has a much shorter review record, 157 reviews averaging 4.2 out of 5 on the queen listing, so the ComfortLuxe Plus remains the safer default for people who do not sleep hot.
