King Split Head Medium Mattresses with a Removable Cover Moisture-Wicking Mattresses Compatible with Adjustable Bed Default Category
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
Hundreds of our mattresses come with a removable, washable cover — unzip and take it off to machine-wash or spot-clean, which is great for allergies, kids, spills and keeping your bed fresh between deep cleans.

You'll find every firmness from plush to extra firm, from about $109 to premium.

Moisture-wicking mattresses are built to keep you dry — drawing sweat and moisture away from your body and letting it evaporate instead of pooling against the surface. Using moisture-wicking and breathable cover fabrics (like Tencel and performance knits) plus ventilated foams and coil airflow, they help you stay fresh and dry through the night. They're especially worth a look if you deal with night sweats, run warm and sweaty, or are managing temperature changes from menopause. You'll find moisture-wicking builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line. Sleep hot and want active cooling?

Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: wicks sweat and moisture away so the surface stays dry • How it works: moisture-wicking & breathable covers (Tencel, performance knits), ventilated foams, coil airflow • Best for: night sweats, sweaty sleepers, and temperature changes from menopause • The benefit: a drier, fresher sleep surface — less clammy, less trapped heat • Related: cooling (sleeps cold) · temperature-regulating (balanced temp) · breathable (airflow) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
