If you wake up sweaty at 2 a.m., the mattress is often the culprit. Dense all-foam beds hold body heat, and in warmer parts of California (inland SoCal, the Central Valley, or any LA apartment without central air) that heat has nowhere to go. This guide covers the best cooling mattress for hot sleepers by type and budget, and explains which cooling features actually make a difference.
Our picks: best cooling mattress for hot sleepers
| Pick | Type | Why it sleeps cool | Best for |
|---|---|---|---|
| Purple RestorePremier | Grid hybrid | Open GelFlex Grid plus CoolFlex coils; Purple’s coolest Restore model | Hot side sleepers |
| Avocado Green | Organic latex hybrid | Latex, wool and organic cotton breathe and wick moisture; coils add airflow | Natural-materials shoppers, back and stomach sleepers |
| Saatva Classic | Coil-on-coil hybrid | Two coil layers and an organic cotton cover keep air moving | Most sleepers who want a classic feel |
| Purple Restore | Grid hybrid | Same grid concept at a lower price than RestorePremier | Value-minded hot sleepers |
Best overall cooling mattress: Purple RestorePremier
Purple’s GelFlex Grid is mostly open air by volume, so heat escapes instead of building up around you. RestorePremier adds a deeper 3-inch grid and CoolFlex coils, each wrapped in a foam pillar, and Purple claims it is the coolest model in the Restore line. The soft feel suits side sleepers best. See our Purple model comparison and Purple mattress review.
Best natural cooling mattress: Avocado Green
Latex is naturally more breathable than memory foam, and Avocado pairs it with wool and organic cotton, which help pull moisture away from the body. The pocketed coil base adds airflow. Its firmer feel suits back and stomach sleepers; side sleepers may prefer the pillow-top version. Read our Avocado Green mattress review.
Best cooling hybrid with a classic feel: Saatva Classic
With two layers of coils and a breathable organic cotton cover, the Saatva Classic sleeps noticeably cooler than all-foam beds while giving you a traditional hotel-style pillow-top feel and a choice of three firmness levels. Read our Saatva Classic review.
Best value cooling pick: Purple Restore
If RestorePremier is over budget, the base Restore keeps the open grid and responsive coils at a lower price, with a medium feel that works for back and combination sleepers.
What makes a mattress sleep cool?
- Coils: a hybrid’s coil layer lets air circulate. This is the single biggest cooling factor.
- Comfort materials: latex and polymer grids breathe better than dense memory foam. If you want foam, look for gel-infused or open-cell foam.
- Cover: organic cotton, wool, lyocell/TENCEL or phase-change “cool-to-the-touch” fabrics help, but they matter less than what is underneath.
- Firmness: softer beds let you sink in, which means more contact and more trapped heat. Medium to medium-firm usually sleeps cooler.
Cooling memory foam: is it enough?
Cooling memory foam mattresses use gel, copper, graphite or open-cell foam to pull heat away, and they are a big improvement over traditional memory foam. But for true hot sleepers, they rarely match a hybrid or latex bed. If you love the memory foam feel, choose a cooling memory foam hybrid instead of an all-foam model. Not sure which type you want? See hybrid vs memory foam.
Cheaper ways to sleep cooler
- Cooling sheets: linen or percale cotton make a real difference. See our best cooling sheets guide.
- A cooling topper: a gel or latex topper can cool down a hot foam bed. See our best mattress toppers.
- A breathable protector: skip vinyl-backed protectors, which trap heat.
- The room: many sleep experts suggest a bedroom temperature in the mid-60s °F, plus a fan for airflow.

Best cooling mattress FAQ
What type of mattress is best for hot sleepers?
A hybrid or latex mattress. Coils and latex let heat escape much better than dense all-foam beds.
Do cooling mattresses really work?
They cannot lower your body temperature, but breathable materials let heat and moisture escape faster, so many hot sleepers feel noticeably more comfortable.
Is memory foam bad for hot sleepers?
Traditional memory foam tends to trap heat. Gel-infused or open-cell foam helps, especially in a hybrid design.
Is a firm or soft mattress cooler?
Firmer mattresses usually sleep cooler because you sink in less, leaving more of your body exposed to air.

[…] Start cooling the room now, not at lights-out. A bedroom that has been closed up on a hot inland day takes time to come down. Open windows if the outside air has cooled, or run the fan or AC early so the room is already comfortable when you get into bed. (Sleep Foundation on bedroom temperature) The bed is part of that cooling job — see our guide to the best cooling mattresses for hot sleepers. […]
