King Queen Medium Springwall® Temperature-Regulating Mattresses Compatible with Adjustable Bed Edge Support Mattresses Adjustable Bed Base Friendly 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.
Queen mattresses measure 60" × 80" — the most popular size in Canada. They give couples comfortable room to share and single sleepers space to stretch out, while still fitting most bedrooms. Compare every queen option below by brand, feel, and price.
Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium
Springwall is a proudly Canadian-made brand known for chiropractic-minded support and durable, value-driven construction. 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
Edge support mattresses are reinforced around the perimeter so the edge feels as solid as the middle — you can sleep right up to the side without that sinking, roll-off feeling, sit on the edge to get dressed without it caving, and use the full surface of the bed. It's a feature that matters most for couples sharing the space, anyone who sits on the edge to get in and out of bed, and heavier-weight sleepers. These are mostly our pocket-coil and hybrid mattresses with full-perimeter coils or foam-encased edges — from Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: a reinforced perimeter so the edge stays firm — no sinking or rolling off • Why it matters: more usable sleep surface, easier to sit on the edge and get in and out of bed • Best for: couples sharing space, anyone who sits on the edge, and heavier-weight sleepers • How it works: full-perimeter pocket coils or foam-encased edges (mostly coil & hybrid; all-foam edges are softer) • Brands: Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster & NM • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery

How the Mattress Selector Works

The selector asks the questions a good salesperson asks in the first two minutes — who the bed is for, your sleep position, your body type, where you ache, how warm you sleep, the feel you prefer, whether you want a pillow top, and (optionally) your budget — then uses your answers to narrow the range down to a shortlist. It draws on the same mattresses you can browse by hand, including Beautyrest, Serta, Sealy, Springwall, Tempur-Pedic and Stearns & Foster.

Answer the feel question honestly rather than aspirationally — if you’ve slept well on firm beds your whole life, say firm. Side sleepers generally need more give at the shoulder and hip, back and stomach sleepers want less sink so the spine stays neutral, and body weight changes how deeply any mattress compresses — which is why two people can lie on the same bed and honestly call it soft and firm. Whatever the selector suggests is a starting point, not a verdict: you can lie on the result at any of our seven Ontario showrooms, and every mattress it recommends carries the 365-night sleep trial.

A Filter, Not an Oracle

It narrows the full mattress range to a shortlist using what you tell it about how you sleep — treat the result as a starting point for browsing, not a verdict.

Matched to How You Sleep

Sleep position drives support needs: side sleepers generally need more give at the shoulder and hip, while back and stomach sleepers usually do better with less sink.

Protected by the 365-Night Trial

No form can know how a bed feels after three weeks — the 365-night sleep trial covers that part. Every mattress it recommends carries the trial, clearance and discontinued stock excepted — that’s sold as-is.

No Commission, No Steering

Our sleep experts aren’t paid commission — they earn the same whichever mattress you pick, and the same whether you buy today or not.

Frequently Asked Questions About the Mattress Selector

What does the mattress selector ask?
Who the bed is for, your sleep position, your body type, where you ache, how warm you sleep, the feel you prefer, whether you want a pillow top, and your budget. Budget is optional — leave it blank and you’ll still see a range of matches.
Is the mattress quiz accurate?
It’s 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 — but it can’t tell you which of three well-matched mattresses you’ll personally love. Only lying on them can, which is what our showrooms and the 365-night sleep trial are for.
Will it push me toward expensive mattresses?
Nobody here earns more for selling you a dearer bed — our staff aren’t paid commission. What’s 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.
Do I have to use the selector to shop?
No. If you already know what you want, browse all mattresses directly and filter by feel — plush to extra firm — by type like memory foam or hybrid, or by size. The selector exists for the much more common case of not knowing where to start.
Can I try my recommendation in person?
Yes — find your nearest of our seven Ontario showrooms and lie on your shortlist. Floor models are shared across the network: if a style is on display at any one store, its sizes are available to order company-wide, stock permitting.
What if the recommendation turns out to be wrong?
Then it’s 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 — any trial short enough to expire before that has happened isn’t much of a trial.

Prefer to Browse — or Talk to a Person?

The selector is a shortcut, not a requirement. Browse the full range at your own pace, or visit a showroom and tell a non-commissioned sleep expert how you sleep — they do the same narrowing by hand, with better follow-up questions than any form can ask.
