Queen Split Head Queen Full Size King Split Head Medium Springwall® Serta® Mattresses for Side Sleepers All Mattresses

Queen mattresses measure 60" × 80" — the most popular size in Canada. They give couples comfortable room to share and single sleepers space to stretch out, while still fitting most bedrooms. Compare every queen option below by brand, feel, and price.
Double/Full mattresses measure 54" × 75" — fifteen inches wider than a twin, giving a single sleeper plenty of room to spread out. They suit teens, single adults, and smaller bedrooms or guest rooms, and work for couples who prefer a cozier fit. Compare every double/full option below by brand, feel, and price.
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 side, the right mattress cushions your shoulders and hips so your spine stays aligned and pressure points don't wake you. That's why side sleepers do best on our plush and medium-feel mattresses — especially euro-top and pillow-top, memory foam and hybrid models that contour to your curves and relieve pressure. We carry hundreds of side-sleeper-friendly options across every brand — Sealy, Serta, Beautyrest, Tempur-Pedic, iComfort, Stearns & Foster and our own NM line — from about $171 to premium. Not sure on feel? Side sleepers usually prefer softer, balanced against how much support you like. Every mattress includes a 365-night sleep trial and free delivery across Canada. • Why it matters: side sleeping concentrates weight on your shoulders and hips — you need cushioning there • Best feel for side sleepers: plush or medium (softer surfaces contour pressure points) • Best constructions: euro-top & pillow-top, memory foam and hybrid • Helps with: shoulder and hip pressure from side sleeping • Hundreds of options across every brand, from about $171 to premium • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
