Extra Firm Premium Mattresses Cooling Mattresses Compatible with Adjustable Bed Adjustable Bed Compatible Mattresses Mattress Selector

Extra firm mattresses are the firmest, most supportive feel we carry — a hard, no-sink surface that holds your body on top of the mattress rather than letting it settle in. They're built for stomach sleepers, heavier-weight sleepers and anyone who finds a standard firm mattress still too soft, delivering maximum support and spinal alignment. Most use a tight-top or high-density foam construction (including orthopedic Chirofoam), with budget-friendly options that keep extra-firm support affordable. Shop Beautyrest, Serta, Chirofoam, Springwall and our own NM line — from $152, with free delivery across Canada. • Feel: extra firm is the firmest of our four comfort levels — a hard, no-sink surface • Best for: stomach sleepers, heavier-weight sleepers, and anyone who wants maximum support • Choose this over firm if a standard firm mattress still feels too soft • Consider firm or medium if you sleep on your side or want any cushioning • Constructions: tight-top and high-density foam (including orthopedic Chirofoam) • Brands: Beautyrest, Serta, Chirofoam, Springwall & NM • Prices: from $152 — an affordable, value-focused selection
Premium is the sweet spot between everyday value and luxury — name-brand mattresses with better materials, thicker comfort layers and more advanced support, without the flagship price tag. This is where you'll find recognizable comfort lines like Sealy Posturepedic Plus, Serta Perfect Sleeper and Perfect Day, Beautyrest Harmony, Chirofoam memory foam and Springwall Chiropractic — in euro-top, pillow-top, hybrid, memory foam and even organic latex builds, across every firmness from plush to extra firm. Most premium mattresses run from about $400 to $1,400. Every one includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "premium" means: name-brand comfort and upgraded materials — a step up from value, below the luxury flagships • Featured lines: Sealy Posturepedic Plus, Serta Perfect Sleeper & Perfect Day, Beautyrest Harmony, Chirofoam, Springwall Chiropractic • Builds: euro-top, pillow-top, hybrid, memory foam and organic latex • Every firmness from plush to extra firm • Typically about $400 to $1,400 • Looking higher or lower? See our luxury or great-value mattresses • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
If you sleep hot, the right mattress can make all the difference. Our cooling mattresses are built to draw heat away from your body and keep you comfortable all night — using cooling technologies like gel-infused memory foam, cool-to-the-touch and phase-change covers, graphite and copper infusions, and breathable pocket-coil airflow. You'll find cooling builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in foam, hybrid and pocket-coil, from plush to firm. If you wake up sweaty or run warm at night, start here. Every mattress includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • Best for: hot sleepers, night sweats, or anyone who runs warm • Cooling technologies: gel-infused memory foam, cool-to-the-touch & phase-change covers, graphite/copper infusions, breathable coil airflow • Builds: gel memory foam, hybrid and pocket-coil • Across every brand and firmness, plush to firm • Why it helps: draws heat away and improves airflow so you sleep cooler • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
Not every mattress can bend with an adjustable base — but these can. Every mattress here is built to flex with the head and foot articulation of an adjustable base without damaging the comfort layers, so you can read, relax in Zero-Gravity or elevate your legs with confidence. In fact, over 90% of our mattresses are adjustable-compatible, spanning memory foam, hybrid and pocket-coil constructions from every brand — NM, Sealy, Serta, Beautyrest, Tempur-Pedic, Stearns & Foster and more — at every budget from about $109 to premium. Foam and hybrid models flex most easily, while rigid, thick tight-top innersprings generally don't. Pair any of these with one of our adjustable bases, and every mattress comes with a 365-night sleep trial and free delivery across Canada. • What this means: mattresses built to flex with an adjustable base's head & foot articulation • Over 90% of our mattresses are adjustable-compatible — every brand, every budget ($109+) • Best constructions for adjustable bases: memory foam, hybrid and pocket-coil • What usually won't work: rigid, thick tight-top innersprings that don't bend • Pairs with our adjustable bases (including split-king for independent sides) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
