King Hybrid Breathable Mattresses Compatible with Adjustable Bed Temperature-Regulating 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.
Hybrid mattresses combine a pocket coil support core with substantial foam or latex comfort layers — pairing the support, bounce, and cooling of coils with the pressure relief of foam. It's the most universally appealing build, suiting nearly every sleep style. Compare every hybrid option below by brand, feel, and profile.
Breathable mattresses are built to move air, not trap it. Through ventilated and open-cell foams, breathable knit and Tencel covers, and pocket-coil airflow, they let heat and moisture escape instead of building up under you — so your sleep surface stays fresher, drier and more comfortable through the night. It's a great fit if you sweat at night, live in a humid climate, or just don't like that stuffy, sunk-in feel. You'll find breathable builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in foam, hybrid and pocket-coil. Sleep especially hot? See our cooling mattresses for active heat-wicking. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: airflow-focused builds that let heat and moisture escape instead of trapping them • How it works: ventilated/open-cell foams, breathable knit & Tencel covers, pocket-coil airflow • The benefit: a fresher, drier, less stuffy sleep surface • Best for: sweaty sleepers, humid climates, or anyone who dislikes a sunk-in, stuffy feel • Sleep hot? See cooling mattresses; want a steady temp? See temperature-regulating • Across every brand and firmness • 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
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
