Premium Side Sleeper Adjustable Bed Base Friendly All

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? See our luxury or great-value mattresses • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery

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
