Plush Temperature-Regulating Mattresses Memory Foam Mattresses
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

How to Choose the Right Memory Foam Mattress
Memory foam mattresses contour to your body shape, relieving pressure at the shoulders, hips, and lower back while absorbing motion so partner movement doesn't transfer across the bed. The key decision factors are foam density, firmness level, and cooling technology. Higher-density foams (1.8+ lb/ft³) retain their shape longer and provide more durable support, while lower-density foams offer a softer initial feel at a lower price point. National Mattress carries memory foam models from Tempur-Pedic, Serta iComfort, Sealy Cocoon, Chirofoam, and our own NM Cozy series in firmness levels from extra firm to plush.
If you sleep hot, look for graphite-infused or gel-infused memory foam with a cool-touch cover — these materials draw heat away from the sleep surface more effectively than traditional memory foam. Side sleepers generally need a medium or plush model for adequate shoulder and hip relief, while back and stomach sleepers benefit from firm or extra firm options that prevent the pelvis from sinking too deeply. Over 98% of our memory foam mattresses are adjustable base compatible, and all use CertiPUR-US® certified foam.
Cooling Technology
Graphite-infused, gel-infused, and CoolFeel™ cover options across iComfort, TEMPUR®, and Sealy Cocoon collections to manage sleep temperature.
Low Motion Transfer
Memory foam absorbs movement rather than transferring it — ideal for couples and light sleepers who are disturbed by partner movement.
Pressure Point Relief
Body-contouring foam cradles hips, shoulders, and joints to reduce pressure points — a key benefit for side sleepers and those with joint discomfort.
Canadian-Made
Over 72% of our memory foam mattresses are manufactured in Canadian factories with free delivery and 10–15 year warranty coverage.
