Medium Mattresses Plush Mattresses Serta® Perfect Sleeper® Adjustable Bed Compatible Mattresses Temperature-Regulating Mattresses Serta Mattresses

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
Serta Perfect Sleeper mattresses offer an exceptional balance of cushioning and support, featuring zoned coil systems and cooling memory foams to help Canadians achieve deeper, more refreshing sleep every night.
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
A temperature-regulating mattress works to keep you at a comfortable, balanced temperature all night and all year — not just cooling you down, but adapting as your body and the seasons change so you don't wake up too hot or too cold. These mattresses use heat-responsive and breathable materials — phase-change covers, gel and graphite foams, Tencel and natural fibres, and airflow-promoting coils — to absorb and release warmth as needed. It's ideal if you run hot and cold, share a bed with a partner who sleeps at a different temperature, or just want consistent comfort through every season. You'll find temperature-regulating builds across every brand — Sealy, Serta, Beautyrest, iComfort, Tempur-Pedic, Chirofoam and our own NM line. Sleep hot specifically? See our cooling mattresses. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it does: holds a balanced, neutral temperature — adapts so you're not too hot or too cold • How it works: phase-change covers, gel & graphite foams, Tencel/natural fibres and breathable coil airflow • Best for: people who run hot and cold, couples with different sleep temperatures, and year-round comfort • Cooling vs regulating: cooling sleeps cold (for hot sleepers); regulating holds a steady, balanced temp • Across every brand and firmness • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
