Side Sleeper Protectors
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

Express ShippingHow to Choose the Right Mattress Protector
A mattress protector is one of the most cost-effective ways to extend the life of your mattress and maintain a hygienic sleep environment. The right protector blocks spills, sweat, dust mites, and allergens from reaching your mattress, without trapping heat or adding noise. At National Mattress, our protectors range from budget-friendly waterproof covers to premium natural wool options, all designed to fit mattresses up to 18–20” deep and work seamlessly on adjustable bases.
Start by deciding which surface material suits your sleep style: cotton terry absorbs moisture and feels soft against the skin, Tencel™ (cool-touch) wicks heat for temperature-sensitive sleepers, quilted microfibre adds a plush comfort layer, organic bamboo offers natural breathability, and wool regulates temperature year-round. All waterproof models use a thin TPU (thermoplastic polyurethane) membrane rather than vinyl, this keeps the protector noiseless and breathable while blocking 100% of liquids. Using a protector is also strongly recommended to help preserve your mattress warranty, since stains from spills or moisture can void manufacturer coverage.
