Memory Foam Temperature-Regulating Mattresses Cooling Mattresses Sealy Mattresses

Memory foam mattresses contour to your body, relieving pressure at the hips and shoulders while absorbing motion so you won't feel your partner move. They give a cradling, "hug" feel that suits side sleepers and couples. Browse every memory foam option below by brand, feel, and profile.
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
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
