Back Sleeper NM® HD+™ Core Mattress Collection — High‑Density Foam, Zoned Lumbar & Edge Support 6 Inches Grey All Mattresses

Back sleepers do best on a mattress that supports the lower back while gently following the spine's natural curve — typically a medium to medium-firm feel. The options below balance support and pressure relief for back sleepers. Compare them by brand, feel, and profile.
Meet NM® HD+™ Core—mattresses built around high‑density foam for durable support, low motion transfer for quieter nights, zoned lumbar for alignment, and reinforced edges for full‑width comfort. Available in firm, medium, and plush feels across Twin, Twin XL, Full/Double, Queen, and King.

Shop 200+ mattresses from Serta, Beautyrest, Sealy, Tempur-Pedic, Springwall, and Stearns & Foster at National Mattress — available in Single/Twin through King sizes from $99 to $6,640. Choose from innerspring, euro-top, memory foam, hybrid, and latex constructions in four firmness levels from extra firm to plush. Every mattress is manufactured in Canadian factories using CertiPUR-US® certified foams and ships free across Canada with a 365-night sleep trial, price match guarantee, and manufacturer warranty coverage up to 25 years.
