Medium Couples Combination Sleepers Temperature-Regulating Mattresses Hypoallergenic Mattresses NM® Mattresses and Accessories
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.
Most people do not hold one position all night. If you start on your side, roll to your back and finish on your stomach, you need a mattress that works in all three positions rather than one tuned for a single posture. That usually means a medium to medium-firm feel with responsive comfort layers. Too soft and your hips sink when you turn onto your back or stomach. Too firm and your shoulder takes the pressure when you are on your side. The mattresses below sit in that middle band, and several use pocket coils or latex that reposition quickly as you move, so you are not fighting the surface every time you turn. Every mattress here comes with our 365-night sleep trial, so you can find out how it feels after a few weeks rather than a few minutes in a showroom. If you want to try before you buy, all seven of our Ontario showrooms carry combination-friendly models on the floor.
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
Hypoallergenic mattresses are made to resist the things that trigger allergies and disrupt sleep — dust mites, mould, mildew and bacteria — using antimicrobial and naturally resistant cover materials like bamboo and Tencel, plus CertiPUR-US® certified, low-VOC foams. The result is a cleaner, fresher sleep surface that's gentler on sensitive skin and easier on allergy and asthma sufferers. You'll find hypoallergenic builds across brands like Sealy, Serta, Beautyrest, iComfort, Springwall, Evergreen and our own NM line, in foam, hybrid and pocket-coil. If allergies or sensitivities affect your sleep, start here. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: built to resist dust mites, mould, mildew and bacteria • How it works: antimicrobial and naturally resistant covers (bamboo, Tencel) plus CertiPUR-US®, low-VOC foams • Best for: allergy and asthma sufferers, sensitive skin, and anyone who wants a cleaner sleep surface • The benefit: fewer allergens, a fresher feel, gentler on sensitivities • Across brands and builds: foam, hybrid and pocket-coil • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery

Express ShippingHow to Choose Within the NM Line
The NM line is our own label, and it covers the whole bed: sprung and all-foam mattresses, box springs, a solid wood platform bedframe, headboards, pillows, sheets and a waterproof protector. Work from the sleep surface outward. The coil models are built on heat-tempered drawn spring steel in Bonnell, pocket coil, foam-encased pocket coil and individually pocketed configurations, and the difference is how they behave: pocketed coils compress one at a time and isolate movement, while a connected coil system shares load for a firmer, more uniform feel. The all-foam models use high-density polyurethane support foam with no springs at all, which removes bounce and noise. Within the line, NM Orthopedic Classic, PLUS and Supreme are the sprung builds, NM Cozy is memory foam, NM HD+ Core is high-density foam, and NM Hi-Loft Elite and NM Essential cover euro top and hybrid feels.
Then come the layers around the mattress. A box spring is not just a spacer, because its profile decides how high you sit: a standard box spring runs about 9 inches deep and a low profile one about 5, so stepping down gains you roughly four inches of clearance rather than half the height. A platform version is thinner again, and NM offers platform, low profile, standard and high profile options, with the depth listed on each. Aim for a finished bed where the top of the mattress lands near your knee as you stand beside it, and ask about split options if your staircase or hallway has a tight turn. Above the mattress, the waterproof protector is the piece most people skip and later regret. What wears a mattress out is mechanical, foam fatigue in the comfort layers and coil set underneath, so a protector is not the thing keeping the bed alive: it is there for hygiene, and for keeping the mattress in the condition a warranty claim depends on. NM pillows include charcoal, copper and lavender infused options alongside shredded memory foam, duck feather, microfiber and wool, so match loft to your sleeping position.
Coils or All Foam
Pocketed springs isolate motion, connected coils feel firmer and more uniform, and all-foam cores remove bounce and noise entirely.
Profile Sets Bed Height
Platform, low profile, standard and high profile change the finished height by inches. See how standard and low profile compare.
Protect It From Day One
A waterproof protector keeps sweat and spills out of the foam, which matters for hygiene and for keeping the mattress in the condition a warranty claim depends on. Our protector guide explains what to look for in a cover.
Frame and Headboards
The solid wood platform bedframe comes in a natural and a walnut finish, and the George and Layla headboards pair with it. See bedroom essentials.
