The 10 Best Full/Double Size Mattresses in Canada (2026) — Tested & Ranked

• Solo adults and teens who want firm, no-fuss support for the lowest price in the group
• Anyone who wants a two-sided bed they can flip to even out wear over the years
• Restless sleepers — it scored a perfect 10 for responsiveness and ease of movement

• A firm, on-top feel — side sleepers who want a deep cradle should look at picks 3 or 4
• Not compatible with an adjustable base

The NM Orthopedic Supreme is a true two-sided coil bed: 300 individually-pocketed springs on thick 12.5-gauge tempered steel, dual layers of HD high-density foam, and a breathable cotton-blend cover on both faces so you can flip it to balance wear. In our testing it posted standout edge support (9.74) and a perfect responsiveness score, with a light contour rather than a swallowing hug. Surface temperature peaked in the low-30s, keeping it cool for a thicker firm build. As one of our most-purchased mattresses online and in-store, it is the rare bed that wins on both proven popularity and per-dollar value — a flippable Full for well under $400.

• Eco-conscious solo sleepers who want certified organic materials in a single bed
• Allergy-prone people — the organic cotton, wool and latex build is naturally hypoallergenic
• Anyone prioritising longevity: it earned a perfect durability score and a perfect off-gassing score

• A medium, on-top feel rather than a plush sink — deep-cradle fans should see picks 4 or 5
• Costs more than the foam beds at the top of this list

The Evergreen Organic Latex pairs an organic cotton cover, organic wool and a layer of natural latex over an 842-coil pocketed support unit with a foam-encased perimeter. Latex is the longest-lasting comfort material made, and that shows in the top scores in this group for both durability (10) and off-gassing (10) — under seven hours to clear in our testing. Spinal support measured a near-perfect 9.75 thanks to the 13-gauge tempered-steel coils, and surface temperature stayed below the average bed. For a Full-size sleeper who wants a green, breathable bed built to outlast everything around it, this is the cleanest pick on the page.

• Solo side and combination sleepers who want a deep, cushioned cradle
• Hot sleepers — it earned a perfect 10 for cooling in our testing
• Anyone who wants the most complete all-rounder in the group, with the highest brand score

• The deepest-feeling, most premium bed here — priced accordingly
• Strict back sleepers may prefer the firmer support of picks 7 or 9

The Sealy Posturepedic Luxury is the most well-rounded bed on this list, and it has the construction to back it up: GelSense MAX memory foam and SmartLatex over a zoned 958-coil core with a reinforced SolidEdge PRO perimeter. It topped the field for cooling (a perfect 10) thanks to the SealyCool cover, settling to the low-20s at rest, and posted a 9.41 for pressure relief with a genuine deep-cradle feel. Spinal alignment measured 9.6 on the 13.75-gauge coil unit. It is the priciest Sealy here, but for a solo sleeper who wants one bed that does everything well in a Full, nothing else matches its breadth.

• Side sleepers and anyone with shoulder or hip pressure who wants an enveloping cradle
• Light sleepers who share the bed occasionally — it scored 9.45 for motion isolation
• Hot sleepers — the CoolFeel graphite top earned a perfect cooling score

• The softest, deepest cradle in the group — firm-support seekers should look elsewhere
• Edge support is fair rather than firm, as expected from a plush 14" build

The Serta Perfect Comfort X is built for pressure relief: three full inches of Perfect Conform graphite memory foam and PillowSoft layers over a 1,050-coil 5-zone ActiveX system. In our testing the surface gave more than three inches toward the deep end of its range — a "Very Deep" wrapped cradle that ranked among the most enveloping beds in its class. It paired that softness with the best spinal-alignment number on the page (9.88) and a perfect cooling result, so the sink never turns into a hot, sagging dip. For a solo sleeper who wants their shoulders and hips to disappear into the bed, this is the relief specialist.

• Solo sleepers who want a true luxury bed and a tall, plush 15.5" profile in a Full
• Hot sleepers — the Sleep Climate cooling cover earned a perfect cooling score
• Anyone who wants flagship coil engineering: 1,850 T3 triple-stranded coils plus micro-coils

• The most expensive coil bed here, and a tall profile that needs deeper-pocket sheets
• An immersive, deep-hug feel — not for sleepers who dislike sinking in

The Beautyrest Centennial is Beautyrest's flagship line, and the construction reads like it: self-response latex and gel memory foam over an 1,850-coil T3 triple-stranded system reinforced with a micro-coil layer. Few beds we test sleep as cool — a perfect cooling score, settling into the low-20s overnight despite four inches of plush comfort layering. Spinal support measured 9.79 and durability earned full marks, reinforced against both core sag and surface impressions. The cradle is an "Extremely Deep," immersive hug. For a Full-size buyer who wants the most luxurious bed on the page, this is it.

• Couples sharing a Full who want a true Medium feel that suits the widest range of bodies
• Anyone who values quick, easy repositioning — it scored a perfect 10 for responsiveness
• Hot sleepers on a budget — the CleanProtect cover kept it cool in our testing

• A Full is snug for two adults — size up to a Queen if you both need real personal space
• Edge support is solid but not the firmest in the group

The Sealy Posturepedic Plus 1000 Series hits a true Medium — the most universally agreeable feel, which is exactly what you want when two people share one bed. Nearly five inches of SealyComfort HD and gel HD foam sit over an 846-coil pocketed core with a SolidEdge HD perimeter, so each sleeper's movement stays on their own side and repositioning is effortless (a perfect responsiveness score). Cooling came in strong at 9.41 and spinal alignment at 8.92. As one of our better-selling Sealy hybrids, it is the value-minded couples pick — just remember a Full is cozy for two, so it suits closer sleepers or a guest room best.

• Back and stomach sleepers who need firm, on-top support and a flat-spine feel
• Anyone with back concerns — it earned a perfect 10 for spinal support, the best on the page
• Hot sleepers — a perfect cooling score from the Cold PE surface and flow-through coils

• An "Extremely Minimal," almost floating feel — side sleepers may want more cushion
• Lower pressure-relief score (7.5), in line with its firm, on-top design

The Springwall Chiropractic is endorsed by the Canadian Chiropractic Association, and our testing shows why: a perfect 10 for spinal support off 1,432 pocketed coils on heavy 13.75-gauge tempered steel, paired with a micro-coil comfort layer and graphite-gel PCM foam. It is a firm, near-floating bed — sinkage measured at the shallow end with an "Extremely Minimal" feel, which is exactly what keeps the hips lifted and the spine flat for back and stomach sleepers. It also posted a perfect cooling score and a perfect responsiveness score. For a Full-size sleeper who wants maximum, posture-first support without paying for plush, this is the firm specialist.

• Teens, guest rooms and first apartments where price matters most
• Firm-support seekers who still want a touch of conforming up top from the cool-gel layer
• Anyone who wants a roll-packed bed that ships compressed and sets up in minutes

• A slim 10" profile — less plush cushioning than the taller beds above it
• Firm overall, so dedicated side sleepers may prefer pick 4

The NM 10" Firm Euro Top is the budget hero of the list and one of our highest-velocity sellers, full stop. It packs a genuine 842-coil pocketed support unit built from 13-gauge tempered steel under a VLS cool-gel memory foam and HD foam comfort layer — real hybrid construction at a price most foam-only beds beat. Spinal support measured a near-perfect 9.8 in our testing, and it ships roll-packed in a box for easy setup in a condo or a teen's room. For a Full-size sleeper who wants the most proven, supportive bed for the least money, this is the clear value pick.

• Solo sleepers who want the balanced medium-firm middle ground in a brand-name Sealy
• People who change positions through the night — it scored 9.88 for responsiveness
• Anyone who wants firm edges to sit and dress on, rated Excellent in our testing

• Carries a 5-year warranty rather than the 10-year coverage on most picks here
• A lower coil count than the pricier Sealy hybrids above it

The Sealy Posturepedic 800 Series is the brand's accessible medium-firm Euro top, and it nails the do-everything middle. A 3.5-inch SealySupport HD comfort layer over 660 Posture Touch pocketed coils on heavy 13.75-gauge steel gives a true deep-cradle feel that still keeps the hips lifted. In our testing it posted a 9.88 for responsiveness — near-instant rebound when you move — with firm, Excellent-rated edges and a cool-running CleanProtect surface. Spinal support measured 8.67. As one of our popular mid-range Sealy beds, it is the balanced medium-firm pick for a Full at a fair price; just note the 5-year warranty.

• Solo sleepers who want the most hand-built, premium bed in a Full, no budget cap
• Anyone prioritising longevity — it earned a perfect durability score on its IntelliCoil core
• Hot sleepers — the Tencel cooling cover delivered a perfect cooling result in our testing

• By far the most expensive bed here, and a tall 16" profile needing extra-deep sheets
• Comfort foams are US-built, then assembled in Canada (see the disclosure below)

The Stearns & Foster Lux Estate is the most meticulously built bed on this list: a hand-tufted, latex-and-PrimaSense gel comfort system over the patented IntelliCoil double-stage spring unit, wrapped in a sustainably-sourced Tencel cooling cover. It earned perfect scores for durability, off-gassing and cooling in our testing, with a near-perfect 9.91 for spinal support — the IntelliCoil firms up progressively under heavier load to keep the spine level. The feel is a balanced medium cradle in a tall 16" profile. For a Full-size buyer who simply wants the finest craftsmanship available, this is the flagship.

Made-in-Canada note: Stearns & Foster mattresses are assembled in Canada using premium US-made comfort foams and coil components, then finished domestically — which is why they qualify alongside our fully Canadian-built picks.
