Queen Clearance Mattresses Adjustable Bed Compatible Mattresses Mattress Selector

Queen mattresses measure 60" × 80" — the most popular size in Canada. They give couples comfortable room to share and single sleepers space to stretch out, while still fitting most bedrooms. Compare every queen option below by brand, feel, and price.
Clearance is where you'll find our deepest mattress discounts — open-box, floor-model and last-unit beds from premium brands like Sealy, Serta, Beautyrest, Simmons, Tempur-Pedic and iComfort, marked down well below regular price to clear space for new stock. Because these are one-of and limited-quantity items, the sizes and models change constantly and the best deals sell fast — when it's gone, it's gone. If you're hunting for a premium mattress at a bargain price and don't mind a floor model or an opened package, this is the place to start. Free delivery across Canada. • What's in clearance: open-box, floor-model and last-unit mattresses • Our deepest discounts — premium brands well below regular price • Brands: Sealy, Serta, Beautyrest, Simmons, Tempur-Pedic, iComfort & Springwall • Limited quantities — one-of items in specific sizes, while they last • Best for bargain hunters who want a premium bed for less • Free delivery across Canada
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
