NM® Temperature-Regulating Mattresses Adjustable Bed Compatible Mattresses Compatible with Adjustable Bed Grey Mattresses Canada Mattress Selector: Find Your Match in a Few Questions

NM mattresses are National Mattress's own line — quality construction at honest, direct prices across firmness levels and builds. Compare every option below by feel, size, and price.
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
These mattresses feature a grey or neutral-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.

Answer a short set of questions — who the bed is for, your sleep position, your body type, where you ache, how hot you sleep, the feel you prefer, whether you want a pillow top, and your budget — and the selector narrows 167 mattresses down to a shortlist. It draws on the full range stocked here: Beautyrest (38 models), Serta (27), Sealy (24), Springwall (23), NM (17), Serta iComfort (16), Tempur-Pedic (8), Stearns & Foster (6), Evergreen (4) and Chirofoam (4).

Feel is the answer worth getting right, and there is real choice at every point on the scale: across these 167 mattresses there are 59 firm builds, 47 plush, 44 medium and 15 extra firm. Budget is optional — leave it blank and you will still see a range. Whatever the selector suggests, you can lie on the result at any of our seven Ontario showrooms, and every mattress here carries a 365-night sleep trial, which is the part that actually protects you if the shortlist is wrong.

How the mattress selector works

The selector is a filter, not an oracle. It asks the questions a good salesperson asks in the first two minutes and uses your answers to narrow 167 mattresses down to a shortlist. It cannot know the things nobody could know from a form — how a bed feels to you after twenty minutes on it, or after three weeks — so treat the result as a starting point rather than a verdict.

What it asks, and why each answer matters

Who the bed is for. A guest room, a growing child and a primary bed for two adults are three different problems, and the sensible answer changes with each.

Sleep position. Side sleepers generally need more give at the shoulder and hip; back and stomach sleepers generally want less sink so the spine stays neutral. It is the single most useful thing to know about how somebody sleeps.

Body type. Weight changes how deeply any given mattress compresses, which is why two people can lie on the same bed and honestly describe it as soft and firm. A build that reads medium at one weight reads plush at another.

Where you ache. Lower-back complaints often trace to a bed too soft to hold the spine neutral; shoulder and hip complaints often trace to one too firm to let them settle in. The direction of the fix depends on where it hurts.

How hot you sleep. Coil and hybrid constructions move air better than dense all-foam ones. Memory foam contours closely and insulates while it does it — a genuine trade-off, not a defect.

Preferred feel. Worth answering honestly rather than aspirationally. If you have slept well on firm beds your whole life, say firm.

Pillow top or not, and budget. Both shape the shortlist. Budget is explicitly optional — it helps with ordering rather than acting as a hard cut-off, and you will always be shown a range.

Questions people ask about the selector

Is the mattress quiz accurate? It is accurate about what it can measure and silent about the rest. It narrows the field using what you told it about position, body type and feel. It cannot tell you which of three well-matched mattresses you will personally love — only lying on them can, which is what the showrooms and the 365-night trial are for.

Do I have to use it? No. If you already know you want a plush queen hybrid, filter for it directly or call and describe it. The selector exists for the much more common case of not knowing where to start.

Will it steer me toward expensive mattresses? Nobody here earns more for selling you a dearer bed — our staff are not paid commission. What is true is that better-built mattresses tend to cost more, so a shortlist weighted toward quality can skew upward. If that happens, set a budget and run it again, or sort the results by price and work from the other end.

What if the result is wrong? Then it is wrong, and the 365-night sleep trial is how you fix it. A mattress needs a few weeks to break in and your body needs a few weeks to adjust, so any trial short enough to expire before that has happened is not much of a trial.

Prefer to talk to a person?

The selector is a shortcut, not a requirement. Call 1-800-631-4883, email support@nationalmattress.ca, or visit any of our seven Ontario showrooms and tell someone how you sleep. Our sleep experts do the same narrowing by hand, ask better follow-up questions than any form can, and earn exactly the same whether you buy the cheapest mattress on the floor, the most expensive one, or nothing at all today.
