4.8 Rating 42 Reviews
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.

“I’ve been looking for a mattress that provides real support, and the NM HD 8" Extra-firm delivers. It is a true extra-firm feel—very supportive with almost no 'sink,' which has been great for my back alignment. The high-density foam feels durable and solid, and I appreciate the decade-long warranty for peace of mind. The breathable cotton quilted top is a nice touch; it adds a bit of surface comfort without making the bed feel soft or trapping heat”
