Dormeo Premium Mattress Topper review

Dormeo builds this topper differently from everything else on Costco's shelf. Instead of a single sheet of foam it uses Octaspring units, foam springs that each move independently, arranged in zones that are firmer under the middle of the body and gentler under the shoulders and legs. Dormeo says the structure pushes out body heat and draws in fresh air as you move, and describes the feel as medium. The interior combines memory foam and poly foam, the queen is 3 inches thick and weighs 27 lbs, and the cover is removable and machine washable but should be laid flat to dry. The cost is the drawback: Costco listed the queen at $314.99 on November 11, 2026, about twice the price of the Novaform and Serenity foam toppers. Its 980 reviews averaged 4.4 out of 5 on the queen listing.
