King Split Head Back Sleeper Shop Mattresses By Popularity
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
