Medium Premium Temperature-Regulating Mattresses Mattresses With Eco-Friendly and Sustainable Materials

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
Premium is the sweet spot between everyday value and luxury — name-brand mattresses with better materials, thicker comfort layers and more advanced support, without the flagship price tag. This is where you'll find recognizable comfort lines like Sealy Posturepedic Plus, Serta Perfect Sleeper and Perfect Day, Beautyrest Harmony, Chirofoam memory foam and Springwall Chiropractic — in euro-top, pillow-top, hybrid, memory foam and even organic latex builds, across every firmness from plush to extra firm. Most premium mattresses run from about $400 to $1,400. Every one includes a 365-night sleep trial, price-match guarantee and free delivery across Canada. • What "premium" means: name-brand comfort and upgraded materials — a step up from value, below the luxury flagships • Featured lines: Sealy Posturepedic Plus, Serta Perfect Sleeper & Perfect Day, Beautyrest Harmony, Chirofoam, Springwall Chiropractic • Builds: euro-top, pillow-top, hybrid, memory foam and organic latex • Every firmness from plush to extra firm • Typically about $400 to $1,400 • Looking higher or lower?

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

How to Choose an Eco-Friendly Mattress in Canada

The most important distinction in sustainable mattresses is what the comfort layers and cover are actually made from. Organic latex, sourced from rubber tree sap and certified to GOTS or OEKO-TEX® Standard 100, is the gold standard for eco-conscious sleepers because it is naturally durable, hypoallergenic, and biodegradable. Evergreen organic latex models at National Mattress use organic cotton covers with organic wool flame barriers, avoiding synthetic fire retardants entirely. For shoppers who prefer a traditional feel, brands like Springwall and NM use soy-based BioFoam™ and BioComfort™ foams that replace a portion of petroleum-based polyols with plant-derived alternatives, while Beautyrest Harmony Lux mattresses feature SEAQUAL™ fabric woven from recycled ocean plastic. Stearns & Foster wraps every Estate and Lux Estate model in sustainably sourced Tencel™ lyocell covers that are moisture-wicking and produced in a closed-loop process.

Look for third-party certifications rather than unverified marketing claims: CertiPUR-US® confirms foam is free of ozone depleters, heavy metals, and PBDEs, while OEKO-TEX® Standard 100 tests the finished textile for over 350 harmful substances. Every mattress at National Mattress carries at least one of these certifications, and the majority are manufactured in Canadian factories, reducing the carbon footprint associated with overseas shipping.

Frequently Asked Questions About Eco-Friendly Mattresses

What materials are used in eco-friendly mattresses?
Common sustainable materials include organic latex, organic cotton and wool, soy-based foams, bamboo-infused fabrics, Tencel™ lyocell, and SEAQUAL™ recycled ocean plastic. The specific materials vary by brand, Evergreen uses certified organic latex and wool, while Beautyrest Harmony Lux uses recycled ocean-plastic covers.
How is an eco-friendly mattress different from a regular mattress?
Eco-friendly mattresses replace some or all petroleum-based foams with plant-derived or natural alternatives and use organic or recycled cover fabrics. They typically produce less off-gassing, carry third-party environmental certifications like OEKO-TEX® or GOTS, and often use natural flame barriers such as wool instead of chemical retardants.
Do eco-friendly mattresses produce less off-gassing?
Yes. Mattresses made with organic latex, wool, and CertiPUR-US® certified foams produce significantly less volatile organic compound (VOC) emissions than conventional models. Natural latex and organic cotton covers have minimal chemical odour, making them a preferred choice for chemically sensitive sleepers and nurseries.
What certifications should I look for in an eco-friendly mattress?
The three most important certifications are CertiPUR-US® (foam safety), OEKO-TEX® Standard 100 (textile safety across 350+ substances), and GOTS (organic fibre chain of custody). Third-party verification is essential, terms like “natural” and “green” are unregulated marketing terms without a certification behind them.
Are eco-friendly mattresses more expensive?
Compare current product prices in the size you need, alongside the materials and construction that matter to you. Before ordering, read our delivery information, sleep trial terms, and manufacturer warranty information.
Which eco-friendly mattress is best for side sleepers?
Side sleepers generally need medium to plush comfort for pressure relief at the shoulder and hip. The Evergreen 14” Euro-top organic latex hybrid provides responsive contouring with organic wool and latex comfort layers. Use our mattress selector tool to filter by sleep position and eco-friendly features for a personalised recommendation.
