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.
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options. Shop plush models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic in memory foam, hybrid and pocket-coil builds — with free delivery across Canada. • Feel: plush is the softest of our four comfort levels (plush, medium, firm, extra firm) • Best for: side sleepers and lighter-weight sleepers — cushions shoulders and hips • Consider firmer if: you sleep on your back or stomach, are heavier, or want more support • Plush constructions: pillow-top, euro-top, plush memory foam and hybrid • Builds: memory foam, hybrid and pocket-coil • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort & Tempur-Pedic • Prices: from $224 to premium

Browse by comfort (plush, medium, firm) or by type (memory foam, hybrid, pocket coil, traditional). Using an adjustable base? See our adjustable-bed-compatible mattresses. Every order includes a 365-night sleep trial and free delivery across Canada.

How to Choose Between Mattress Brands

National Mattress carries the major mattress brands under one roof — Beautyrest, Serta and Sealy, homegrown Canadian makers like Springwall, Chirofoam, Evergreen and Marshall Mattress, and our own NM house line. A brand name tells you who built a mattress, not how it will feel: two beds from the same maker can sleep completely differently, and two beds from rival makers can sleep almost identically. That’s why the useful order of operations is feel first, then size, then brand — picking a comfort level narrows the field without locking you into a single manufacturer.

Each line earns its place differently. Beautyrest brought pocketed coils into mass production; Tempur-Pedic brought memory foam to mattresses; Stearns & Foster anchors the premium end; Mlily leans into memory foam and hybrids; and Evergreen builds certified organic latex. Not every line here is a mattress brand, either — HealthGuard, Natura, Leggett & Platt, Sinca and Aireloom cover protectors, pillows, bedding, adjustable bases and bed frames instead. Whichever label you land on, every mattress here carries the same 365-night sleep trial, and the advice comes from sleep experts who aren’t paid commission.

Canadian-Built Depth

The mattresses we stock from Beautyrest, Serta, Springwall, Sealy, Chirofoam, Evergreen and Marshall Mattress are built in Canadian factories.

One Trial, Every Brand

Every mattress — whichever brand builds it — includes the 365-night sleep trial, so choosing between labels never means gambling a year’s sleep. Clearance and discontinued stock is the exception: it’s sold as-is.

Compare Brands in Person

Floor models are shared across our seven Ontario showrooms — if a style is on display at any store, its sizes can be ordered company-wide, stock permitting.

Price-Matched, Then Beaten

Find a lower price on the same or a comparable mattress at an authorised Canadian dealer and we’ll match it and beat it — compared on construction, not the name on the label.

Frequently Asked Questions About Our Mattress Brands

What mattress brands does National Mattress carry?
The mattress lines are Beautyrest, Serta and its iComfort range, Sealy, Springwall, Stearns & Foster, Tempur-Pedic, Mlily, Evergreen, Marshall Mattress, Chirofoam and our own NM line. HealthGuard, Natura, Leggett & Platt, Sinca and Aireloom are accessory lines instead, covering protectors, pillows, bedding, bases and frames. The grid above is the live list — it updates as the range changes.
Which mattress brands are made in Canada?
The mattresses we stock from Beautyrest, Serta, Springwall, Sealy, Chirofoam, Evergreen and Marshall Mattress are built in Canadian factories. Tempur-Pedic, Stearns & Foster and Mlily mattresses are US-built, and our NM house line comes out of both Canadian and US factories.
Which mattress brand is best?
There’s no single answer — and any retailer who gives you one is selling you something. The best brand is whichever one builds a mattress in the feel and size you need at a price you’re comfortable with. Our sleep experts aren’t paid commission, so nobody here gains from steering you toward a label — and the Mattress Selector narrows the field by how you actually sleep instead.
Do all brands come with the same sleep trial?
Every mattress from every brand includes the 365-night sleep trial — a mattress needs a few weeks to break in and your body a few weeks to adapt, which is why a year is more useful than thirty days. Clearance and discontinued stock is the exception — it’s sold as-is. Accessories run on their own terms too: pillows, protectors and bedding carry a shorter return window, while adjustable bases and bed frames are final sale once opened.
Can I try these brands in a showroom?
Yes — across seven Ontario showrooms. Find your nearest store and lie on the finalists side by side. Floor models are shared network-wide: if a style is on display at any one location, its sizes are available to order company-wide, stock permitting. Clearance and discontinued stock is the exception — it’s sold as-is.
Do warranties differ between brands?
Yes. Warranty coverage is set by each manufacturer and varies by brand and model — see the manufacturer’s warranty page for how coverage works before you buy if it matters to your decision.

Not Sure Which Brand Is Right for You?

Brand loyalty is earned lying down, not reading logos. Answer a few questions and the selector narrows the field to a shortlist — or ask a non-commissioned sleep expert to do the narrowing for you.
