King Luxury Mattresses Adjustable Bed Compatible Mattresses Temperature-Regulating Mattresses Blue 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.
Luxury is the top of our lineup — the finest mattresses we carry, built with the most advanced comfort technology and the premium materials money can buy. This is where you'll find Tempur-Pedic's signature TEMPUR® memory foam (Tempur-LuxeAlign and ProAlign), Serta's iComfort PRO all-latex and europillowtop beds, and Stearns & Foster's hand-finished Lux Estate, alongside other premium flagships from Beautyrest and Sealy. Expect deeper pressure relief, superior motion isolation and exceptional durability, in plush, medium and firm. Luxury mattresses range from about $819 to $6,999, and every one includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "luxury" means: our finest, flagship mattresses — the most advanced comfort tech and premium materials • Featured flagships: Tempur-Pedic (LuxeAlign & ProAlign), Serta iComfort PRO, Stearns & Foster Lux Estate • Premium builds: TEMPUR® memory foam, all-latex, thick europillowtop and hybrid • What you get: deeper pressure relief, superior motion isolation and exceptional durability • Price range: about $819 to $6,999 • On a budget?

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
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
These mattresses feature a blue-accent or cool-tone cover — and since that cover sits under your sheets, colour won't change how you sleep. To find the right bed, shop by size (twin to king), comfort (plush, medium, firm), or type (memory foam, hybrid, pocket coil). Every mattress includes a 365-night sleep trial and free delivery across Canada.
