Boyd Sleep 3" Multi-Zone Cooling Gel Foam Mattress Topper review

Boyd Sleep's topper is the budget foam pick on Costco's site. It uses what Boyd calls GelLux technology, liquid gel fused into a high-performance foam, cut into a multi-zone wave pattern with circular channels that the listing says add lumbar support and reduce motion transfer. Air hole perforations run through the foam to help heat escape. The foam is CertiPUR-US certified and carries a 5-year manufacturer warranty. Costco listed the queen at $104.99 on November 11, 2026, $35 less than the Sealy and $55 less than the ComfortLuxe Plus. Two details need attention before buying: the queen measures 58 by 78 inches, a little short of a standard 60 by 80 inch mattress, and there is no cover, so the foam can only be spot cleaned with water. Its 966 reviews averaged 4.0 out of 5 on the queen listing.
