Plush Medium 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

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.
