Medium Mattresses for Stomach Sleepers Low Motion Transfer Mattresses Compatible with Adjustable Bed Adjustable Bed Compatible Mattresses Edge Support Mattresses Temperature-Regulating 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
Stomach sleepers need a firmer, more supportive mattress — one that keeps your hips and midsection from sinking, so your spine stays flat and your lower back doesn't arch and ache. That's why our stomach-sleeper picks skip the plush feels and focus on firm and medium-firm support across tight-top, foam, hybrid and euro-top builds. We carry hundreds of stomach-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: stomach sleeping lets the hips sink and the lower back arch — you need firmer support to stay flat • Best feel for stomach sleepers: firm to medium-firm (we skip plush for this position) • Best constructions: tight-top, foam and hybrid for even, supportive lift • Hundreds of options across every brand, from about $59 to premium • Want the firmest support? See our firm and extra-firm mattresses • Every order: 365-night sleep trial, price-match guarantee & free Canada-wide delivery
If your partner tosses, turns or gets up during the night, a low-motion-transfer mattress keeps their movement from becoming your problem. These mattresses use individually wrapped pocket coils and motion-absorbing memory foam to isolate movement to one side of the bed — so when one of you shifts, the other barely feels it. It's one of the most important features for couples, and for anyone who shares a bed with a restless sleeper, a pet, or a partner on a different schedule. You'll find low-motion-transfer builds across every brand — Sealy, Serta, Beautyrest, Simmons, iComfort, Tempur-Pedic, Chirofoam and our own NM line — in pocket-coil, hybrid and memory foam, every firmness from plush to firm. Every mattress includes a 365-night sleep trial and free delivery across Canada. • What it means: movement stays on one side — your partner's tossing won't wake you • How it works: individually wrapped pocket coils and motion-absorbing memory foam (vs connected innersprings that transfer motion) • Best for: couples, light sleepers, and anyone sharing a bed with a restless partner or pet • Builds: pocket-coil, hybrid and memory foam • Across every brand and firmness • 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
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
