Twin Size Full Size Evergreen® Sleep Compatible with Adjustable Bed Adjustable Bed Compatible Mattresses Mattress Selector

Twin Size mattresses measure 39" × 75" — the most compact standard adult size. They're ideal for children's rooms, bunk beds, daybeds, single sleepers, and guest or small bedrooms where space is tight. Compare every single/twin option below by brand, feel, and price.
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.
Evergreen mattresses focus on natural, eco-conscious materials and breathable comfort for a cleaner, cooler sleep. Compare every option below by feel, size, and price.
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
