King Springwall® Top-Rated Mattresses Adjustable Bed Compatible Mattresses Compatible with Adjustable Bed White Mattresses Grey Mattresses Mattress Selector

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.
Springwall is a proudly Canadian-made brand known for chiropractic-minded support and durable, value-driven construction. Compare every option below by feel, size, and price.
These are our top-rated mattresses — the highest-rated, best-reviewed beds chosen by verified customer reviews. Instead of guessing, shop the models real Canadians rate most highly for comfort, support and durability, spanning every brand and comfort level from plush to firm. Every mattress is backed by our 365-night sleep trial, price-match guarantee and manufacturer's warranty, and ships free across Canada — so a top-rated pick is an easy, low-risk choice. Browse best-reviewed models from Sealy, Serta, Beautyrest, Tempur-Pedic, Stearns & Foster and our own NM line. • What "top-rated" means: our highest-rated mattresses by verified customer reviews • Rated by real Canadians for comfort, support and durability • Spans every brand and comfort level (plush, medium, firm, extra firm) • Every order: 365-night sleep trial, price-match guarantee and manufacturer's warranty • Free delivery across Canada • Brands include Sealy, Serta, Beautyrest, Tempur-Pedic, Stearns & Foster & NM
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

Most of our mattresses come in a clean, neutral white or off-white cover — and since that cover sits under your sheets, colour won't change how you sleep. To find the right bed, shop by what actually matters: your size (twin to king), your comfort level (plush, medium, firm), or your preferred type (memory foam, hybrid, pocket coil). Every mattress includes a 365-night sleep trial and free delivery across Canada.


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.
