Queen Plush Temperature-Regulating Mattresses Edge Support Mattresses Adjustable Bed Compatible Mattresses Serta® Mattresses and Accessories
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
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
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
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

Express ShippingHow to Choose the Right Serta Mattress
Serta® names its coil systems for how the support layer is organised, which makes the name the most useful thing on the label. Where a name says zoned, the coil unit is divided along its length into sections set to different resistances, so the middle of the bed can hold your hips up while the head and foot sections stay softer under shoulders and calves. The 1000 and 950 Series 3-Zoned Coil System and the 1050 3-Zoned Coil System split the surface three ways, while the 1250 and 2550 Series 5 ZoneActive Pocket Coil System divides it into five, giving shorter, more gradual steps between firm and soft. Serta also builds on the 800, 825 and 850 Edition Custom Support® Coil Systems.
Two other pieces of engineering matter when comparing models. Best Edge® Foam Encasement is a rigid foam frame built around the coil unit, and Serta specifies it model by model rather than as part of any one coil system, so check the model you are looking at. It stops the perimeter collapsing when you sit on it and makes the outer few inches usable for sleeping rather than a slope you roll away from. In the comfort layers, gel memory foam has a gel component mixed through the foam, which raises the thermal mass so the surface takes longer to reach body temperature; airflow, an open cell structure and the cover do the sustained work. Moulded memory foam is poured into a shaped mould so its contours are formed rather than cut. You can also explore the Serta iComfort collection. Comfort choices run across Extra Firm, Firm, Medium and Plush.
Three Zones or Five
A zone count tells you how finely support changes from head to foot: five sections step in smaller increments than three. Which one reads better is personal, so lie on both. Our zoned support guide goes deeper.
Reinforced Perimeter
Best Edge® Foam Encasement frames the coils in rigid foam so the edge holds firm, and Serta specifies it model by model. That widens the area you can actually sleep on and steadies the mattress when you sit down. See our edge support selection.
Gel and Warm-Up Time
Memory foam holds warmth because it wraps closely around you. A gel infusion raises the thermal mass of the foam, so the surface takes longer to reach body temperature; sustained cooling comes from airflow, an open cell structure and the cover.
Firmness Choices
Choose from Extra Firm, Firm, Medium and Plush, and remember that a thicker comfort layer can make two beds with the same coil system feel different.
