Medium Mattresses for Back Sleepers Marshall® Handcrafted Luxury Mattresses

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
If you sleep on your back, your mattress needs to support the natural curve of your spine — firm enough that your hips don't sink, with just enough give to fill the gap at your lower back. That's why back sleepers do best on our medium and medium-firm mattresses, which balance support and contouring across foam, hybrid, euro-top and tight-top builds. We carry hundreds of back-sleeper-friendly models from every brand — Sealy, Serta, Beautyrest, Tempur-Pedic, iComfort, Stearns & Foster, Chirofoam and our own NM line — from about $59 to premium. Every mattress includes a 365-night sleep trial and free delivery across Canada. • Why it matters: back sleeping needs support that keeps the spine neutral and fills the lumbar curve • Best feel for back sleepers: medium to medium-firm (support without sinking) • Works across builds: foam, hybrid, euro-top and tight-top • Hundreds of options across every brand, from about $59 to premium • Prefer firmer support, or sleep with back pain? See our firm mattresses • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
