Medium Temperature-Regulating Mattresses Compatible with Adjustable Bed Natural & Organic Mattresses USA Mattress Selector

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
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
For a cleaner, more eco-conscious sleep, our natural and organic mattresses are built with materials you can feel good about — natural Talalay latex, organic cotton and wool covers, plant-based and soy-derived foams, and recycled fibres, with low-VOC, CertiPUR-US® certified components. They're a great fit if you want fewer synthetic chemicals, more sustainable materials, or a naturally breathable, hypoallergenic feel. You'll find genuinely certified-organic options — like GOTS organic cotton and organic latex from Natura and Evergreen — alongside natural-material and eco-friendly builds from Serta iComfort ECO, Sealy, Beautyrest and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What "natural materials" means: Talalay latex, organic cotton & wool, plant-based/soy foams and recycled fibres • Certified-organic options: GOTS organic cotton and organic latex (Natura, Evergreen) • Eco-friendly builds: Serta iComfort ECO (REPREVE recycled) plus low-VOC, CertiPUR-US® foams • Best for: shoppers who want fewer synthetic chemicals, sustainable materials, or a naturally breathable feel • Looking specifically for latex? See our latex mattresses • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
