Novaform ComfortLuxe Plus Gel Memory Foam Mattress Topper review

Novaform is the topper brand Costco stocks most, and the ComfortLuxe Plus is its best-documented model. It is a 3-inch layer of phase change gel memory foam inside a stretch cover woven with cool-touch fibers. Costco's listing says the cover stretches like a fitted sheet over mattresses up to 17 inches deep and can go through the washer and dryer, which removes the usual hassle of spot cleaning a foam topper. The foam is CertiPUR-US certified and made in the USA, and the topper carries a 10-year limited warranty. Novaform describes it as suited to side, back and stomach sleepers. It was listed at $159.99 for a queen on costco.com on November 11, 2026, and its queen listing showed 4,022 reviews averaging 4.4 out of 5, the most of any topper in that range. The trade-off is a classic slow memory foam feel; people who want bounce should look at the Dormeo.
