4.8 Rating 100 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.

“I’m so happy I decided to purchase my mattress from National Mattress. From the very first night, I noticed a huge difference in my sleep quality. I’m sleeping deeper, waking up more refreshed, and overall feeling better throughout the day. The comfort and support are exactly what I was looking for—it truly feels like the mattress was made just for me. It’s made such a positive impact that I actually look forward to going to bed every night now! On top of that, the whole experience was smooth and pleasant, and I really appreciate the help I received in choosing the right mattress. I can honestly say I’m enjoying my sleep better than ever. Highly recommend to anyone looking to upgrade their sleep!⭐️⭐️⭐️⭐️⭐️”

“Very firm, stable support. With its HD+ high-density foam core and “extra-firm” rating, this mattress delivers strong support that keeps your spine aligned — especially good for back sleepers or anyone who prefers a very firm sleeping surface.”
