Full Size Medium Compatible with Adjustable Bed Temperature-Regulating Mattresses Hypoallergenic Mattresses All Mattresses
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
A temperature-regulating mattress works to keep you at a comfortable, balanced temperature all night and all year — not just cooling you down, but adapting as your body and the seasons change so you don't wake up too hot or too cold. These mattresses use heat-responsive and breathable materials — phase-change covers, gel and graphite foams, Tencel and natural fibres, and airflow-promoting coils — to absorb and release warmth as needed. It's ideal if you run hot and cold, share a bed with a partner who sleeps at a different temperature, or just want consistent comfort through every season. You'll find temperature-regulating builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line. Sleep hot specifically? See our cooling mattresses. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: holds a balanced, neutral temperature — adapts so you're not too hot or too cold • How it works: phase-change covers, gel & graphite foams, Tencel/natural fibres and breathable coil airflow • Best for: people who run hot and cold, couples with different sleep temperatures, and year-round comfort • Cooling vs regulating: cooling sleeps cold (for hot sleepers); regulating holds a steady, balanced temp • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
Hypoallergenic mattresses are made to resist the things that trigger allergies and disrupt sleep — dust mites, mould, mildew and bacteria — using antimicrobial and naturally resistant cover materials like bamboo and Tencel, plus CertiPUR-US® certified, low-VOC foams. The result is a cleaner, fresher sleep surface that's gentler on sensitive skin and easier on allergy and asthma sufferers. You'll find hypoallergenic builds across brands like Sealy, Serta, Beautyrest, iComfort, Springwall, Evergreen and our own NM line, in foam, hybrid and pocket-coil. If allergies or sensitivities affect your sleep, start here. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: built to resist dust mites, mould, mildew and bacteria • How it works: antimicrobial and naturally resistant covers (bamboo, Tencel) plus CertiPUR-US®, low-VOC foams • Best for: allergy and asthma sufferers, sensitive skin, and anyone who wants a cleaner sleep surface • The benefit: fewer allergens, a fresher feel, gentler on sensitivities • Across brands and builds: foam, hybrid and pocket-coil • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
