King Split Head Queen Split Head Double/Full Medium Matelas compatibles avec les lits ajustables Adjustable Bed Base Friendly
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
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

What Makes a Mattress Adjustable Base Friendly?
An adjustable base friendly mattress is designed to flex and bend repeatedly without damaging its internal structure. Not every mattress can handle this — traditional innerspring models with rigid continuous-coil systems and thick euro-tops can crease or lose support when elevated. The best options for adjustable bases include memory foam, latex, hybrid pocket-coil, and individually wrapped pocket coil mattresses, all of which articulate smoothly at the head and foot sections.
At National Mattress, every product listed in this category has been verified as adjustable base compatible by the manufacturer. Key features to consider include mattress height (models under 14″ generally flex most easily), coil type (pocket coils move independently and bend better than connected coils), and foam density (higher-density foams maintain their shape through thousands of flex cycles). If you already own a Lifestyle adjustable base or are planning to pair your mattress with one, look for models with low motion transfer and pressure point relief to get the full benefit of zero-gravity and elevated sleeping positions.
