Full Size Medium Traditional Breathable Mattresses Adjustable Bed Compatible Mattresses Mattress Selector

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.
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
Traditional mattresses have a tight-top surface — the comfort layers are smoothly upholstered into the mattress with no added pillow-top or euro-top. That means a firmer, more supportive and responsive feel, excellent durability, and a clean classic look without the "sink" of a plush topper. Compare every tight-top option below by brand, feel, and price.
Breathable mattresses are built to move air, not trap it. Through ventilated and open-cell foams, breathable knit and Tencel covers, and pocket-coil airflow, they let heat and moisture escape instead of building up under you — so your sleep surface stays fresher, drier and more comfortable through the night. It's a great fit if you sweat at night, live in a humid climate, or just don't like that stuffy, sunk-in feel. You'll find breathable builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in foam, hybrid and pocket-coil. Sleep especially hot? See our cooling mattresses for active heat-wicking. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: airflow-focused builds that let heat and moisture escape instead of trapping them • How it works: ventilated/open-cell foams, breathable knit & Tencel covers, pocket-coil airflow • The benefit: a fresher, drier, less stuffy sleep surface • Best for: sweaty sleepers, humid climates, or anyone who dislikes a sunk-in, stuffy feel • Sleep hot? See cooling mattresses; want a steady temp? See temperature-regulating • Across every brand and firmness • 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
