Extra Firm Adjustable Bed Compatible Mattresses Low Motion Transfer Mattresses Springwall Mattresses
Extra firm mattresses are the firmest, most supportive feel we carry — a hard, no-sink surface that holds your body on top of the mattress rather than letting it settle in. They're built for stomach sleepers, heavier-weight sleepers and anyone who finds a standard firm mattress still too soft, delivering maximum support and spinal alignment. Most use a tight-top or high-density foam construction (including orthopedic Chirofoam), with budget-friendly options that keep extra-firm support affordable. Shop Beautyrest, Serta, Chirofoam, Springwall and our own NM line — from $152, with free delivery across Canada.
• Feel: extra firm is the firmest of our four comfort levels — a hard, no-sink surface
• Best for: stomach sleepers, heavier-weight sleepers, and anyone who wants maximum support
• Choose this over firm if a standard firm mattress still feels too soft
• Consider firm or medium if you sleep on your side or want any cushioning
• Constructions: tight-top and high-density foam (including orthopedic Chirofoam)
• Brands: Beautyrest, Serta, Chirofoam, Springwall & NM
• Prices: from $152 — an affordable, value-focused selection
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
If your partner tosses, turns or gets up during the night, a low-motion-transfer mattress keeps their movement from becoming your problem. These mattresses use individually wrapped pocket coils and motion-absorbing memory foam to isolate movement to one side of the bed — so when one of you shifts, the other barely feels it. It's one of the most important features for couples, and for anyone who shares a bed with a restless sleeper, a pet, or a partner on a different schedule. You'll find low-motion-transfer builds across every brand — Sealy, Serta, Beautyrest, Simmons, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in pocket-coil, hybrid and memory foam, every firmness from plush to firm. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: movement stays on one side — your partner's tossing won't wake you • How it works: individually wrapped pocket coils and motion-absorbing memory foam (vs connected innersprings that transfer motion) • Best for: couples, light sleepers, and anyone sharing a bed with a restless partner or pet • Builds: pocket-coil, hybrid and memory foam • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
