4.8 Rating 105 Reviews

The NM HD+ Core Advanced 10" extra-firm flippable high-density foam mattress is designed for back and stomach sleepers who prefer to sleep on top of the bed, not in it. Made in Canada, this mattress features a dense HD+ high-density support core with no coils, standing 10 inches tall. It has two finished sleep surfaces and a 25-year warranty. The mattress is extra-firm, rated 12/10, and provides a firmer hold through the middle, where back and stomach sleepers carry the most weight. The HD+ extra-firm high-density foam gives even support, and the mattress is certified by CertiPUR-US, ensuring low-emission foams that are completely fiberglass-free. The mattress is available in king size and comes in white and black colors.
