Medium Plush Premium Mattresses Adjustable Bed Compatible Mattresses Compatible with Adjustable Bed Edge Support Mattresses White Mattresses Mattress Selector

Medium-firmness mattresses — often called medium-firm — sit right between plush and firm, which is why they're the most popular and versatile feel we carry. You get enough cushioning to relieve pressure with enough support to keep your spine aligned, making medium a safe choice for back sleepers, combination sleepers who change positions through the night, and couples who need a compromise between two preferences. Shop medium models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic across memory foam, hybrid, euro-top, pillow-top and tight-top builds — with free delivery across Canada. • Feel: medium sits between plush and firm — balanced and the most versatile of our four comfort levels • Also called "medium-firm" — the middle of the firmness scale • Best for: back sleepers, combination sleepers, couples, and most body types • Consider plush if you sleep on your side; firm if you sleep on your stomach or want more support • Constructions: euro-top, tight-top, pillow-top, memory foam and hybrid • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort, Tempur-Pedic, Springwall & NM • Prices: from $171 to premium
Plush mattresses are the softest comfort level we carry — built with thick pillow-top and euro-top comfort layers (plus plush memory foam and hybrid options) that cradle your shoulders and hips for a soft, sink-in feel. Plush is the top choice for side sleepers and lighter-weight sleepers who need extra cushioning at the pressure points; back and stomach sleepers, or anyone who wants firmer support, may prefer our medium or firm options. Shop plush models from Sealy, Serta, Beautyrest, Stearns & Foster, iComfort and Tempur-Pedic in memory foam, hybrid and pocket-coil builds — with free delivery across Canada. • Feel: plush is the softest of our four comfort levels (plush, medium, firm, extra firm) • Best for: side sleepers and lighter-weight sleepers — cushions shoulders and hips • Consider firmer if: you sleep on your back or stomach, are heavier, or want more support • Plush constructions: pillow-top, euro-top, plush memory foam and hybrid • Builds: memory foam, hybrid and pocket-coil • Brands: Sealy, Serta, Beautyrest, Stearns & Foster, iComfort & Tempur-Pedic • Prices: from $224 to premium
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
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
Edge support mattresses are reinforced around the perimeter so the edge feels as solid as the middle — you can sleep right up to the side without that sinking, roll-off feeling, sit on the edge to get dressed without it caving, and use the full surface of the bed. It's a feature that matters most for couples sharing the space, anyone who sits on the edge to get in and out of bed, and heavier-weight sleepers. These are mostly our pocket-coil and hybrid mattresses with full-perimeter coils or foam-encased edges — from Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster and our own NM line. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: a reinforced perimeter so the edge stays firm — no sinking or rolling off • Why it matters: more usable sleep surface, easier to sit on the edge and get in and out of bed • Best for: couples sharing space, anyone who sits on the edge, and heavier-weight sleepers • How it works: full-perimeter pocket coils or foam-encased edges (mostly coil & hybrid; all-foam edges are softer) • Brands: Springwall (Full Perimeter Comfort Pockets), Sealy, Serta, Beautyrest, iComfort, Stearns & Foster & NM • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery

Most of our mattresses come in a clean, neutral white or off-white cover — and since that cover sits under your sheets, colour won't change how you sleep. To find the right bed, shop by what actually matters: your size (twin to king), your comfort level (plush, medium, firm), or your preferred type (memory foam, hybrid, pocket coil). Every mattress includes a 365-night sleep trial and free delivery across Canada.
