MastersBest Cooling Mattresses for Hot Sleepers
In this guide
The coolest mattresses are hybrids and latex beds: a pocket-coil core lets air move through the mattress, and latex, gel or copper-infused foams and breathable covers keep the surface from storing your body heat. Dense, unventilated memory foam does the opposite. Our top picks for hot sleepers in Canada are the Serta iComfort Opera (best overall), the Organic Meadow Hybrid (best natural), the Dreamstar Double Life Copper (best for couples) and the Dreamstar Prestige Firm (best for heavier sleepers), with the reasoning and buying tips below.
Our cooling picks
- Best overall: Serta iComfort Opera Medium, graphite and gel memory foam
- Best natural latex: Organic Meadow Hybrid Plush, latex and wool over pocket coils
- Best for couples: Dreamstar Double Life Copper Gel Medium, copper gel and motion-isolating coils
- Best for heavier sleepers: Dreamstar Prestige Firm, firm hybrid with breathable layers
- Best firm foam: Serta iComfort Vista Firm
Do Cooling Mattresses Really Work?
Yes, within reason. A cooling mattress cannot air-condition your room, but it can stop heat building up around your body. It does that with breathable covers, gel, copper or graphite foams that conduct heat away from the surface, open-cell or ventilated foams, and coil cores that let air circulate. Hot sleepers who move from a dense all-foam bed to a good hybrid typically notice the difference the first night.
What to Look For in a Cooling Mattress
- Breathable cover: Tencel, organic cotton or performance knit fabrics.
- Gel, copper or graphite-infused memory foam: conducts heat away far better than traditional foam.
- Natural latex: open-celled and temperature-neutral by nature.
- Hybrid construction: individually wrapped pocket coils let air move through the core.
- Phase-change materials: absorb and release heat to hold a steady surface temperature.
- Wool: wicks moisture and regulates temperature in both directions.
Best Cooling Mattresses in Canada for 2026
1. Serta iComfort Opera Medium: best overall cooling mattress
Type: memory foam hybrid. Serta’s iComfort line combines graphite memory foam and gel memory foam, both of which pull heat away from the body, under a cool-touch cover. The medium feel suits all positions, especially combination sleepers, and it works perfectly on an adjustable base.
2. Organic Meadow Hybrid Plush: best natural latex cooling mattress
Type: organic latex and wool over pocket coils. Latex is temperature-neutral and open-celled, wool wicks moisture, and the coil base keeps air moving. Ideal for eco-conscious shoppers, allergy sufferers and anyone who sleeps hot; no synthetic foams, no off-gassing. See our organic mattress guide.
3. Dreamstar Double Life Copper Gel Medium: best for couples
Type: two-sided copper-gel hybrid. Copper is antimicrobial and highly conductive, so the surface stays cool, while the zoned pocket-coil core isolates motion so a restless partner does not wake you. Supportive in every position, with firm foam-encased edges, and flippable for 20 years of use.
4. Dreamstar Prestige Firm: best for heavier sleepers
Type: firm hybrid with breathable layers. Heavier bodies sink deeper and trap more heat; the Prestige Firm’s zoned coils prevent sinkage while its quilted, breathable build keeps air moving around you. Everything you want in a firm mattress.
5. Serta iComfort Vista Firm: best firm cooling foam feel
Type: firm iComfort build with carbon-fibre and gel memory foams for back and stomach sleepers who run hot and prefer a firmer, foam-forward surface.
Which Type of Mattress Sleeps the Coolest?
| Mattress type | Cooling performance | Why |
|---|---|---|
| Latex hybrid | Coolest | Open-cell latex and wool over a coil core |
| Pocket coil / hybrid with gel or copper foam | Very cool | Airflow through the core plus conductive foams |
| Traditional innerspring | Cool | Airflow, but less pressure relief |
| Modern all-foam with gel or open cells | Moderate | Better than old foam, but no core airflow |
| Dense traditional memory foam | Warmest | Traps heat and moisture around the body |
Browse hybrid mattresses and organic latex mattresses for the coolest options.
Tips to Sleep Cooler at Night
- Use a breathable, not plastic-backed, mattress protector.
- Choose cooling pillows and cotton, linen or bamboo sheets.
- Skip heavy comforters and synthetic bedding in summer.
- Keep the bedroom around 18°C and use a fan for airflow.
- Consider an adjustable base; air circulates under the bed instead of being trapped by a solid platform.
We will match you to a cooling mattress that also fits your position, weight and budget.

Frequently asked questions
Do gel memory foam mattresses actually sleep cooler?
Yes, noticeably cooler than traditional memory foam, because the gel conducts heat away from the surface. For the biggest difference, choose gel foam over a pocket-coil core rather than an all-foam bed.
Is latex cooler than memory foam?
Yes. Latex has an open cell structure and does not store heat the way memory foam does, which is why organic latex hybrids are among the coolest mattresses available.
Why does my mattress make me hot?
Dense foam that traps body heat, a non-breathable cover or protector, and a solid platform that blocks airflow underneath are the usual causes. A sagging mattress that lets you sink deeper also traps more heat.
