Full Size Mattresses for Back Sleepers Adjustable Bed Compatible Mattresses Compatible with Adjustable Bed Adjustable Bed Compatible Mattresses Mattress Selector

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.
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
Not every mattress can bend with an adjustable base — but these can. Every mattress here is built to flex with the head and foot articulation of an adjustable base without damaging the comfort layers, so you can read, relax in Zero-Gravity or elevate your legs with confidence. In fact, over 90% of our mattresses are adjustable-compatible, spanning memory foam, hybrid and pocket-coil constructions from every brand — NM, Sealy, Serta, Beautyrest, Tempur-Pedic, Stearns & Foster and more — at every budget from about $109 to premium. Foam and hybrid models flex most easily, while rigid, thick tight-top innersprings generally don't. Pair any of these with one of our adjustable bases, and every mattress comes with a 365-night sleep trial and free delivery across Canada. • What this means: mattresses built to flex with an adjustable base's head & foot articulation • Over 90% of our mattresses are adjustable-compatible — every brand, every budget ($109+) • Best constructions for adjustable bases: memory foam, hybrid and pocket-coil • What usually won't work: rigid, thick tight-top innersprings that don't bend • Pairs with our adjustable bases (including split-king for independent sides) • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
