Extra Firm Springwall Temperature-Regulating Mattresses attresses with a Removable Cover Springwall Mattresses
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.

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
