King Innerspring Great Value Mattresses Temperature-Regulating Mattresses Compatible with Adjustable Bed Cooling Mattresses Adjustable Bed Compatible Mattresses Mattress Selector

King mattresses measure 76" × 80" — the widest standard size, giving each partner the same personal space as a twin. They're the top choice for couples who want maximum room, families who co-sleep, and larger master bedrooms. Compare every king option below by brand, feel, and price.
Innerspring mattresses use a coil support system for a responsive, bouncy feel with strong airflow that sleeps cool. They deliver reliable edge support and a classic "on top of the bed" feel at an accessible price — a fit for back, stomach, and combination sleepers. Compare every innerspring option below.
Great Value is where comfort meets affordability — our most budget-friendly mattresses, starting around $109. These are quality beds, not corner-cut compromises: supportive high-density foam, pocket-coil euro-tops and tight-tops, many made right here in Canada by our own NM and Springwall lines, alongside entry-price models from Sealy, Serta and Beautyrest. Whether you're furnishing a guest room, a kids' room, a rental or a first apartment — or you just don't see the point in overpaying — you'll find a comfortable, well-built mattress here for less. Every one includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "great value" means: our most affordable mattresses — quality builds at low prices, from $109 • Builds: high-density foam, pocket-coil euro-top and tight-top • Mostly Canadian-made value brands (NM, Springwall) plus entry models from Sealy, Serta & Beautyrest • Best for: guest rooms, kids' rooms, rentals, first apartments, or anyone who wants comfort without overpaying • Same guarantees as every mattress: 365-night sleep trial, price-match & free Canada-wide delivery • Stepping up? See our premium and luxury mattresses
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
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
