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.
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
Edge support mattresses are reinforced around the perimeter so the edge feels as solid as the middle — you can sleep right up to the side without that sinking, roll-off feeling, sit on the edge to get dressed without it caving, and use the full surface of the bed. It's a feature that matters most for couples sharing the space, anyone who sits on the edge to get in and out of bed, and heavier-weight sleepers. These are mostly our pocket-coil and hybrid mattresses with full-perimeter coils or foam-encased edges — from Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: a reinforced perimeter so the edge stays firm — no sinking or rolling off • Why it matters: more usable sleep surface, easier to sit on the edge and get in and out of bed • Best for: couples sharing space, anyone who sits on the edge, and heavier-weight sleepers • How it works: full-perimeter pocket coils or foam-encased edges (mostly coil & hybrid; all-foam edges are softer) • Brands: Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster & NM • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
A temperature-regulating mattress works to keep you at a comfortable, balanced temperature all night and all year — not just cooling you down, but adapting as your body and the seasons change so you don't wake up too hot or too cold. These mattresses use heat-responsive and breathable materials — phase-change covers, gel and graphite foams, Tencel and natural fibres, and airflow-promoting coils — to absorb and release warmth as needed. It's ideal if you run hot and cold, share a bed with a partner who sleeps at a different temperature, or just want consistent comfort through every season. You'll find temperature-regulating builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line. Sleep hot specifically? See our cooling mattresses. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: holds a balanced, neutral temperature — adapts so you're not too hot or too cold • How it works: phase-change covers, gel & graphite foams, Tencel/natural fibres and breathable coil airflow • Best for: people who run hot and cold, couples with different sleep temperatures, and year-round comfort • Cooling vs regulating: cooling sleeps cold (for hot sleepers); regulating holds a steady, balanced temp • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
These mattresses are made with the planet — and your health — in mind. Our eco-friendly picks use CertiPUR-US® certified, low-VOC foams made without ozone-depleters, formaldehyde or heavy metals, produced in low-emission, responsibly run facilities — so what you bring into your bedroom is cleaner and lower-impact. You'll find these certified, low-emission builds across brands like Sealy, Serta, Beautyrest, iComfort, Chirofoam, Springwall and our own NM line. Many are also proudly made in Canada — see our Canadian-made mattresses for the full local lineup — and for natural or recycled materials specifically, see our natural & organic and sustainable collections. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: built with certified, low-emission, responsibly manufactured components • Certifications: CertiPUR-US® — low-VOC, made without ozone-depleters, formaldehyde or heavy metals • The benefit: a cleaner, lower-impact mattress with fewer harmful chemicals • Related collections: Canadian-made (local production) · natural & organic (materials) · sustainable (recycled) • Across brands and builds, every firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
These mattresses feature a grey or neutral-tone cover — and since that cover sits under your sheets, colour won't change how you sleep. To find the right bed, shop by size (twin to king), comfort (plush, medium, firm), or type (memory foam, hybrid, pocket coil). Every mattress includes a 365-night sleep trial and free delivery across Canada.
