Medium Mattresses Luxury Mattresses Adjustable Bed Compatible Mattresses Compatible with Adjustable Bed Mattress Selector

Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium
Luxury is the top of our lineup — the finest mattresses we carry, built with the most advanced comfort technology and the premium materials money can buy. This is where you'll find Tempur-Pedic's signature TEMPUR® memory foam (Tempur-LuxeAlign and ProAlign), Serta's iComfort PRO all-latex and europillowtop beds, and Stearns & Foster's hand-finished Lux Estate, alongside other premium flagships from Beautyrest and Sealy. Expect deeper pressure relief, superior motion isolation and exceptional durability, in plush, medium and firm. Luxury mattresses range from about $819 to $6,999, and every one includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "luxury" means: our finest, flagship mattresses — the most advanced comfort tech and premium materials • Featured flagships: Tempur-Pedic (LuxeAlign & ProAlign), Serta iComfort PRO, Stearns & Foster Lux Estate • Premium builds: TEMPUR® memory foam, all-latex, thick europillowtop and hybrid • What you get: deeper pressure relief, superior motion isolation and exceptional durability • Price range: about $819 to $6,999 • On a budget? See our great-value or premium mattresses • 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
