Twin Size Temperature-Regulating Mattresses Bedding & Sheets
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 Sheets and Bedding for Your Mattress
The right sheet set does more than dress your bed — it directly affects sleep temperature, comfort, and how long your mattress stays clean. National Mattress carries three distinct sheet materials so you can match fabric to the way you sleep: Egyptian cotton (200-thread-count long-staple fibre) for a cool, crisp hand feel; bamboo-cotton blend (70/30 bamboo rayon and cotton) for naturally hypoallergenic moisture wicking; and brushed microfiber for wrinkle-free easy care at every price point. For Canadian winters, layering sheets with a Natura wool duvet adds breathable warmth without overheating — wool regulates body temperature more effectively than synthetic fills.
Pocket depth is the most overlooked fit detail: standard sheets suit mattresses up to 12″, while pillow-top and euro-top beds often need 14″–18″ deep-pocket fitted sheets. Every sheet set at National Mattress is OEKO-TEX® Standard 100 certified — independently tested to be free of harmful substances — and all four sheet lines are made in Canada. Pair any set with a waterproof mattress protector to extend mattress life and maintain your manufacturer’s warranty coverage.
