Springwall® Couples Temperature-Regulating Mattresses Adjustable Bed Base Friendly Mattresses with Edge Support
Two people on one mattress creates problems one person never has. One of you gets up early, the other feels it. One sleeps hot, the other is cold. One wants firm, the other wants plush. A mattress for couples has to handle all three. Motion isolation is the first thing to look at. Individually pocketed coils and memory foam absorb movement where a traditional connected innerspring passes it straight across the bed. Edge support is the second, because on a shared mattress the usable sleeping surface is whatever you can lie on without feeling like you might roll off, and weak edges quietly cost you several inches on each side. If your comfort preferences genuinely differ, ask about split configurations rather than compromising on one feel. All seven of our Ontario showrooms let you lie on these together, which is the only real way to test motion transfer. Every one carries the 365-night sleep trial.
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

Express ShippingWhat Is Edge Support and Why Does It Matter?
Edge support refers to the reinforced perimeter structure of a mattress that prevents sagging or roll-off when you sit or sleep near the sides. Mattresses with strong edge support use technologies like foam encasement, reinforced coil borders, or dedicated edge systems, such as Beautyrest’s BeautyEdge®, Sealy’s SolidEdge™ PRO, and Springwall’s SpringWALL Edge System, to create a stable, usable sleeping surface from edge to edge. This effectively increases the functional sleep area by up to 15–20%, which is especially valuable for couples sharing a Queen or King mattress.
When choosing an edge support mattress at National Mattress, consider your mattress type: pocket coil and hybrid models typically deliver the strongest perimeter stability, while memory foam mattresses with high-density foam encasement offer a solid alternative without coils. Firmness also plays a role, firm and extra firm mattresses naturally resist edge compression more than plush models. The edge support mattresses in this collection are CertiPUR-US® certified and manufactured in Canadian factories 🍁.
Reinforced Perimeter
Foam encasement, BeautyEdge®, SolidEdge™, and SpringWALL Edge systems prevent roll-off and sagging along every side of the mattress.
More Usable Sleep Surface
Strong edge support extends the functional sleeping area to the full mattress width, especially important for couples and shared beds.
Easier Entry & Exit
A firm, stable perimeter makes getting in and out of bed easier, a key benefit for older adults and those with mobility concerns.
Canadian-Made Quality
100% of edge support mattresses at National Mattress are manufactured in Canadian factories with free delivery and manufacturer warranty information available.
