Bedding/Sheets Bed Frame Adjustable Bases Extra Firm Side Sleeper NM® Mattresses and Accessories
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

How 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.
