Queen Split Head King Split Head Full Size Extra Firm Pressure Relief Mattresses Serta® Mattresses and Accessories
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.
Extra firm mattresses are the firmest, most supportive feel we carry — a hard, no-sink surface that holds your body on top of the mattress rather than letting it settle in. They're built for stomach sleepers, heavier-weight sleepers and anyone who finds a standard firm mattress still too soft, delivering maximum support and spinal alignment. Most use a tight-top or high-density foam construction (including orthopedic Chirofoam), with budget-friendly options that keep extra-firm support affordable. Shop Beautyrest, Serta, Chirofoam, Springwall and our own NM line — from $152, with free delivery across Canada. • Feel: extra firm is the firmest of our four comfort levels — a hard, no-sink surface • Best for: stomach sleepers, heavier-weight sleepers, and anyone who wants maximum support • Choose this over firm if a standard firm mattress still feels too soft • Consider firm or medium if you sleep on your side or want any cushioning • Constructions: tight-top and high-density foam (including orthopedic Chirofoam) • Brands: Beautyrest, Serta, Chirofoam, Springwall & NM • Prices: from $152 — an affordable, value-focused selection
Pressure relief mattresses are designed to contour to the shape of your body, cushioning the places that take the most weight — your shoulders, hips and joints — so you wake up without the aches and numbness a too-firm surface can cause. They use conforming memory foam, plush pillow-top and euro-top comfort layers, and pressure-mapping hybrids to spread your weight evenly and ease pressure points. They're especially worth a look for side sleepers, anyone with joint pain or arthritis, and lighter-weight sleepers. You'll find pressure-relieving builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in memory foam, hybrid and plush comfort. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: contours to your body to ease pressure at the shoulders, hips and joints • How it works: conforming memory foam, plush pillow-top/euro-top comfort layers, pressure-mapping hybrids • Best for: side sleepers, joint pain or arthritis, and lighter-weight sleepers • The benefit: even weight distribution — fewer aches, less numbness and tossing • Builds: memory foam, hybrid and plush comfort • Related: side sleepers (position) · plush (feel) · memory foam (type) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
