Read National Mattress Canada Reviews

The NM HD+ Advanced 8" extra-firm high-density foam mattress is a solid slab of high-density foam, standing 8 inches tall. It's designed for back and stomach sleepers who prefer to sleep on top of the bed, rather than sinking into it. The mattress features zoned lumbar support, an Edge Guard perimeter, and a seamless, coil-free build that absorbs movement. The foam core has a density of 1.8 lb/ft³, which helps resist softening and body impressions over time. The mattress is made in Canada and is certified by CertiPUR-US. It's available in a queen size and comes in white and black colors.

“Exactly What My Back Needed – A Life-Changing Mattress About 3–4 years ago, I started having back problems from sleeping on a spring mattress. After trying several options and not finding anything firm enough, I gave up and started sleeping directly on the carpet floor. Surprisingly, that completely resolved my back issues—I had no pain at all. Since then, I’ve been on the lookout for an extra firm mattress that could give me the same level of support. I finally found this high-density foam mattress, and it’s exactly what I needed. It replicates the firmness of the floor but with added comfort, and my back feels great. This mattress has been a life changer. I haven’t found anything like it in the market. If you're struggling with back pain and need true firmness, this is the one.”
