Read National Mattress Canada Reviews

The NM HD 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, not in it. The mattress features zoned lumbar support, an Edge Guard perimeter, and a seamless, coil-free build that absorbs movement. The foam core is made in Canada and has a density of 1.8 lb/ft³, which helps resist softening and body impressions over time. The mattress is also CertiPUR-US certified, ensuring the foams meet high standards for safety and quality. It's available in King size and comes in two colors: White and Black.

I had a 12 inch memory foam mattress that always sunk in few minutes after laying down. I was looking for an extra firm mattress, happy to have found this one. This feels hard as a rock, might be too firm for some but I love it. It came with 25 years warranty, hoping it stays the same
