NM® Heavier Bodies Compatible with Adjustable Bed Cooling Mattresses All
NM mattresses are National Mattress's own line — quality construction at honest, direct prices across firmness levels and builds. Compare every option below by feel, size, and price.
Body weight changes what a mattress has to do. More load means more compression through the comfort layers, so a mattress that feels supportive at one weight can bottom out at another, and the edges are usually the first place it shows. The mattresses below are built with that in mind: denser support cores, firmer overall feel, and reinforced perimeters so sitting on the edge to put your shoes on does not collapse it. Higher-density foams and heavier-gauge coils also hold their shape longer under sustained load, which matters more than the first-night feel. If you share the bed, look at the edge support and the motion transfer together, since both get tested harder. Every mattress here carries our 365-night sleep trial, and we price match, so you can take the time to be sure it holds up for you rather than deciding in a showroom.
If you sleep hot, the right mattress can make all the difference. Our cooling mattresses are built to draw heat away from your body and keep you comfortable all night — using cooling technologies like gel-infused memory foam, cool-to-the-touch and phase-change covers, graphite and copper infusions, and breathable pocket-coil airflow. You'll find cooling builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in foam, hybrid and pocket-coil, from plush to firm. If you wake up sweaty or run warm at night, start here. Every mattress includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • Best for: hot sleepers, night sweats, or anyone who runs warm • Cooling technologies: gel-infused memory foam, cool-to-the-touch & phase-change covers, graphite/copper infusions, breathable coil airflow • Builds: gel memory foam, hybrid and pocket-coil • Across every brand and firmness, plush to firm • Why it helps: draws heat away and improves airflow so you sleep cooler • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
