Best-in-Class Mattresses Adjustable Bed Compatible Mattresses Grey Mattresses Mattress Selector

Best-in-Class is where you'll find the very best mattresses we carry — the flagship, top-of-the-line models that lead their category — now on sale. Think Tempur-Pedic's Tempur-LuxeAlign and ProAlign, the Beautyrest Centennial, and luxury beds from Stearns & Foster and Sealy: the deepest comfort technology, premium materials and the highest build quality, with savings of hundreds of dollars on beds that rarely go on sale. If you want the best sleep money can buy at a better price, start here — every best-in-class mattress includes our 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "best-in-class" means: the flagship, top-of-the-line model in each brand's lineup — on sale • Featured flagships: Tempur-Pedic (LuxeAlign & ProAlign), Beautyrest Centennial, Stearns & Foster • Premium materials, the deepest comfort tech and the highest build quality • Save hundreds on beds that rarely get discounted • Best for: shoppers who want the best sleep money can buy, for less • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
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
These mattresses feature a grey or neutral-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). Every mattress includes a 365-night sleep trial and free delivery across Canada.
