Full Size Medium Extra Firm Breathable Mattresses
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
Extra firm mattresses are the firmest, most supportive feel we carry — a hard, no-sink surface that holds your body on top of the mattress rather than letting it settle in. They're built for stomach sleepers, heavier-weight sleepers and anyone who finds a standard firm mattress still too soft, delivering maximum support and spinal alignment. Most use a tight-top or high-density foam construction (including orthopedic Chirofoam), with budget-friendly options that keep extra-firm support affordable. Shop Beautyrest, Serta, Chirofoam, Springwall and our own NM line — from $152, with free delivery across Canada. • Feel: extra firm is the firmest of our four comfort levels — a hard, no-sink surface • Best for: stomach sleepers, heavier-weight sleepers, and anyone who wants maximum support • Choose this over firm if a standard firm mattress still feels too soft • Consider firm or medium if you sleep on your side or want any cushioning • Constructions: tight-top and high-density foam (including orthopedic Chirofoam) • Brands: Beautyrest, Serta, Chirofoam, Springwall & NM • Prices: from $152 — an affordable, value-focused selection

What Makes a Mattress Breathable and How to Choose One
A breathable mattress promotes continuous airflow through its layers, wicking moisture away from your body and dissipating heat before it builds up. This matters most for hot sleepers, couples sharing a bed, and anyone in a climate with warm or humid nights. The key difference between a breathable mattress and a standard cooling mattress is structural: breathable designs use open-cell foams, ventilated coil cores, and moisture-wicking cover fabrics to move air passively, while active cooling relies on gel infusions or phase-change materials to absorb heat. Many mattresses at National Mattress combine both approaches.
Construction type directly affects airflow. Hybrid mattresses with pocket coil cores allow air to circulate beneath the comfort layers, while latex models feature a naturally open-cell structure that resists heat retention. Memory foam mattresses with gel, graphite, or copper infusions also qualify — look for covers labelled CoolFeel™, InfiniCool™, or Cool Touch Stretch Knit, which are engineered for surface-level breathability. All breathable mattresses in this collection use CertiPUR-US® certified foams, and the majority are manufactured in Canadian factories.
