NM HD+ Advanced 8" Extra-firm High Density Foam Mattress - Queen, Certipur-us Certified, Made in Canada Reviews

4.8 Rating 38 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.
