The Novaform LURAcor ComfortPlus 3-Inch Foam Mattress Topper in California King size delivers responsive, uplifting support that goes beyond traditional memory foam. The resilient LURAcor foam features a breathable open-cell design that promotes airflow and helps move excess heat away from the body throughout the night, providing consistent pressure point relief for side, back, and stomach sleepers.

The topper includes a soft-knit, cool-to-touch cover made with breathable fabric and cooling fibers that help lower body temperature for faster sleep onset. The hypoallergenic cover stretches like a fitted sheet to accommodate mattresses up to 17 inches deep and is fully machine washable and dryable, with cooling properties that do not wash out. The California King measures 84 inches long by 72 inches wide by 3 inches high and weighs 29.2 pounds.

The foam is CertiPUR-US certified, made without phthalates, heavy metals, or ozone depleters, and with low VOC emissions. The topper is fiberglass-free and proudly made in the USA. It ships compressed in a box for easy delivery and setup, and is backed by a 10-year limited warranty.
