Full Size King Split Head Queen Split Head Marshall® Mattresses for Standard Bed Frames All Mattresses

Double/Full mattresses measure 54" × 75" — fifteen inches wider than a twin, giving a single sleeper plenty of room to spread out. They suit teens, single adults, and smaller bedrooms or guest rooms, and work for couples who prefer a cozier fit. Compare every double/full option below by brand, feel, and price.
Marshall® is a Canadian name in handcrafted, pocketed-coil sleep. Each Marshall mattress is built in Canada on an 842 tempered pocketed-coil system with high-density encased edge support, spanning the Crafted and Assured series in medium, firm and plush feels, plus matching boxsprings to complete your set. Backed by a 10-year warranty and free next-day delivery in Toronto.
These mattresses are built for a standard bed frame, box spring or platform bed rather than an adjustable base — solid, no-flex support for a classic setup. Shopping by feel or build instead? Browse by comfort (plush, medium, firm) or by type (memory foam, hybrid, pocket coil, traditional). Using an adjustable base? See our adjustable-bed-compatible mattresses. Every order includes a 365-night sleep trial and free delivery across Canada.
