Queen Split Head King King Split Head Memory Foam Black Mattresses All Mattresses

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.
Memory foam mattresses contour to your body, relieving pressure at the hips and shoulders while absorbing motion so you won't feel your partner move. They give a cradling, "hug" feel that suits side sleepers and couples. Browse every memory foam option below by brand, feel, and profile.
These mattresses feature a black or dark-tone cover — and since that cover sits under your sheets, colour won't change how you sleep. To find the right bed, shop by size (twin to king), comfort (plush, medium, firm), or type (memory foam, hybrid, pocket coil). Looking for the Beautyrest® Black® collection? That's a premium brand line, not a colour — browse it on the Beautyrest Black page. Every mattress includes a 365-night sleep trial and free delivery across Canada.

Shop 200+ mattresses from Serta, Beautyrest, Sealy, Tempur-Pedic, Springwall, and Stearns & Foster at National Mattress — available in Single/Twin through King sizes from $99 to $6,640. Choose from innerspring, euro-top, memory foam, hybrid, and latex constructions in four firmness levels from extra firm to plush. Every mattress is manufactured in Canadian factories using CertiPUR-US® certified foams and ships free across Canada with a 365-night sleep trial, price match guarantee, and manufacturer warranty coverage up to 25 years.
