NM® Mattresses and Accessories® Temperature-Regulating Mattresses Mattress in a Box NM
NM mattresses are National Mattress's own line — quality construction at honest, direct prices across firmness levels and builds. Compare every option below by feel, size, and price.
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
Skip the showroom hassle — our mattress-in-a-box beds are compressed, rolled and shipped right to your door in a single, easy-to-carry box. Just bring it to your room, unbox it, and watch it expand to full size in a few hours. These boxed mattresses use foam and hybrid constructions that compress safely without losing comfort, and they span value to premium — from our own NM line, Chirofoam and Springwall to Sealy Cocoon, Serta iComfort and Beautyrest, in every firmness from plush to firm. You get bed-in-a-box convenience with the choice of a full mattress store, plus a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What it is: a mattress compressed and rolled into a box, shipped to your door — unbox and it expands to full size • Setup: carry the box in, unroll, and let it expand (usually within a few hours) • Builds: foam and hybrid (the constructions that compress safely) • Spans value to premium: NM, Chirofoam, Springwall, Sealy Cocoon, Serta iComfort, Beautyrest & more • Why shop here: bed-in-a-box convenience with a full store's selection — many ship fast • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
