Full Size Medium 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.

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.
