NM® Combination Sleepers Compatible with Adjustable Bed Breathable 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.
Most people do not hold one position all night. If you start on your side, roll to your back and finish on your stomach, you need a mattress that works in all three positions rather than one tuned for a single posture. That usually means a medium to medium-firm feel with responsive comfort layers. Too soft and your hips sink when you turn onto your back or stomach. Too firm and your shoulder takes the pressure when you are on your side. The mattresses below sit in that middle band, and several use pocket coils or latex that reposition quickly as you move, so you are not fighting the surface every time you turn. Every mattress here comes with our 365-night sleep trial, so you can find out how it feels after a few weeks rather than a few minutes in a showroom. If you want to try before you buy, all seven of our Ontario showrooms carry combination-friendly models on the floor.
Breathable mattresses are built to move air, not trap it. Through ventilated and open-cell foams, breathable knit and Tencel covers, and pocket-coil airflow, they let heat and moisture escape instead of building up under you — so your sleep surface stays fresher, drier and more comfortable through the night. It's a great fit if you sweat at night, live in a humid climate, or just don't like that stuffy, sunk-in feel. You'll find breathable builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in foam, hybrid and pocket-coil. Sleep especially hot? See our cooling mattresses for active heat-wicking. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: airflow-focused builds that let heat and moisture escape instead of trapping them • How it works: ventilated/open-cell foams, breathable knit & Tencel covers, pocket-coil airflow • The benefit: a fresher, drier, less stuffy sleep surface • Best for: sweaty sleepers, humid climates, or anyone who dislikes a sunk-in, stuffy feel • Sleep hot? See cooling mattresses; want a steady temp? See temperature-regulating • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
