King Split Head Medium Copper, Charcoal or Graphite Infusion Compatible with Adjustable Bed Hypoallergenic Mattresses All
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
These mattresses blend copper, charcoal, graphite or similar minerals into their foam layers or cover fabric. These materials conduct heat well, helping move warmth away from your body, and are also used to help keep the mattress fresh by resisting odour. A good place to start if you sleep warm and want cooling built into the materials themselves.
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
