Medium Plush Couples Side Sleeper Edge Support Mattresses Temperature-Regulating Mattresses NM® Mattresses and Accessories
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options. Shop plush models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic in memory foam, hybrid and pocket-coil builds — with free delivery across Canada. • Feel: plush is the softest of our four comfort levels (plush, medium, firm, extra firm) • Best for: side sleepers and lighter-weight sleepers — cushions shoulders and hips • Consider firmer if: you sleep on your back or stomach, are heavier, or want more support • Plush constructions: pillow-top, euro-top, plush memory foam and hybrid • Builds: memory foam, hybrid and pocket-coil • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort & Tempur-Pedic • Prices: from $224 to premium
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.
If you sleep on your side, the right mattress cushions your shoulders and hips so your spine stays aligned and pressure points don't wake you. That's why side sleepers do best on our plush and medium-feel mattresses — especially euro-top and pillow-top, memory foam and hybrid models that contour to your curves and relieve pressure. We carry hundreds of side-sleeper-friendly options across every brand — Sealy, Serta, Beautyrest, Tempur-Pedic, iComfort, Stearns & Foster and our own NM line — from about $171 to premium. Not sure on feel? Side sleepers usually prefer softer, balanced against how much support you like. Every mattress includes a 365-night sleep trial and free delivery across Canada. • Why it matters: side sleeping concentrates weight on your shoulders and hips — you need cushioning there • Best feel for side sleepers: plush or medium (softer surfaces contour pressure points) • Best constructions: euro-top & pillow-top, memory foam and hybrid • Helps with: shoulder and hip pressure from side sleeping • Hundreds of options across every brand, from about $171 to premium • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
Edge support mattresses are reinforced around the perimeter so the edge feels as solid as the middle — you can sleep right up to the side without that sinking, roll-off feeling, sit on the edge to get dressed without it caving, and use the full surface of the bed. It's a feature that matters most for couples sharing the space, anyone who sits on the edge to get in and out of bed, and heavier-weight sleepers. These are mostly our pocket-coil and hybrid mattresses with full-perimeter coils or foam-encased edges — from Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: a reinforced perimeter so the edge stays firm — no sinking or rolling off • Why it matters: more usable sleep surface, easier to sit on the edge and get in and out of bed • Best for: couples sharing space, anyone who sits on the edge, and heavier-weight sleepers • How it works: full-perimeter pocket coils or foam-encased edges (mostly coil & hybrid; all-foam edges are softer) • Brands: Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster & NM • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
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 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.
