Queen Split Head Extra Firm Edge Support Mattresses Matelas compatibles avec les lits ajustables Temperature-Regulating Mattresses Default Category
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
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
Ce ne sont pas tous les matelas qui peuvent se plier avec une base ajustable — mais ceux-ci le peuvent. Chaque matelas ici est conçu pour fléchir avec l’articulation de la tête et des pieds d’une base ajustable sans endommager les couches de confort, pour lire, relaxer en position zéro gravité ou surélever les jambes en toute confiance. En fait, plus de 90 % de nos matelas sont compatibles avec les bases ajustables, en mousse mémoire, hybride et ressorts ensachés, de toutes les marques — NM, Sealy, Serta, Beautyrest, Tempur-Pedic, Stearns & Foster et plus — et pour tous les budgets, d’environ 109 $ au haut de gamme. Les modèles en mousse et hybrides fléchissent le plus facilement, tandis que les matelas à ressorts rigides et épais à dessus lisse ne s’y prêtent généralement pas. Jumelez-les à l’une de nos bases ajustables — chaque matelas s’accompagne d’un essai de sommeil de 365 nuits et de la livraison partout au Canada. • Ce que ça signifie : des matelas conçus pour fléchir avec l’articulation tête-pieds d’une base ajustable • Plus de 90 % de nos matelas sont compatibles — toutes les marques, tous les budgets (109 $ et plus) • Meilleures constructions : mousse mémoire, hybride et ressorts ensachés • Ce qui ne convient généralement pas : les matelas à ressorts rigides et épais à dessus lisse • Se jumelle à nos bases ajustables (y compris King divisé, pour des côtés indépendants) • Chaque commande : essai de sommeil de 365 nuits, garantie d’égalisation des prix et livraison au Canada — gratuite sur les commandes admissibles
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
