Medium Temperature-Regulating Mattresses Compatible with Adjustable Bed Adjustable Bed Compatible Mattresses Serta® Mattresses and Accessories
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
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

How 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.
