Best cooling mattresses for 2026
Updated June 2026Independently researchedNo paid placement.
If you sleep hot, the Purple Plus Mattress is our top pick because its breathable GelFlex Grid keeps air moving all night long.
The Saatva Classic is the best overall choice for anyone who wants luxury without sleeping hot, while the Helix Midnight is a strong runner‑up for side sleepers who need both support and cooling.
If you regularly wake up drenched in sweat or find yourself flipping your pillow to the cool side, you are not alone. Overheating at night is one of the most common complaints among mattress shoppers, and the wrong bed can trap body heat like a blanket in summer. A genuinely cooling mattress does not just rely on a fancy cover; it uses materials that actively dissipate heat through airflow, phase‑change technology, or thermally conductive foams. When choosing a cooling mattress, look beyond the marketing terms. The most effective designs combine an open structure (like coils or a grid) with covers made from breathable cotton or proprietary cooling fabrics. Memory foam is notoriously heat‑retaining, so hybrid or latex models usually perform better for hot sleepers. The three mattresses below have earned strong reputations for temperature regulation across thousands of owner reviews and expert tests, each suited to a different sleep style or budget.

Frequently asked questions
Why do memory foam mattresses sleep hot?
Dense foam limits airflow. Body heat gets trapped in the foam layers rather than dissipating. Gel infusions help but don't eliminate the issue. Hybrids with coil bases allow much more airflow; Purple's open-grid structure is a different approach that avoids foam heat entirely.
Does a cooling mattress actually make a difference?
Yes, meaningfully for hot sleepers. Hybrid coil construction, gel foam, and open-grid designs all reduce heat retention compared to standard memory foam. The difference is most pronounced for people who currently wake up sweating on an all-foam mattress.
What is the coolest mattress material?
Coil-based hybrids are generally the coolest, air moves freely through the coil layer. Purple's GelFlex Grid is also notably cool. Latex is cooler than memory foam. Dense memory foam is the warmest mattress type.
Do cooling mattress covers help?
Phase-change material covers provide a cool-to-the-touch sensation and can meaningfully help hot sleepers for a few hours. They don't solve the underlying heat retention of a foam mattress for all-night cooling, but they're a lower-cost first step.
Is a cooling mattress enough if I sleep very hot?
For most hot sleepers, yes. For severe heat issues, pair a hybrid or open-grid mattress with breathable bedding (cotton or linen rather than polyester) and consider a mattress cooling pad if needed. The mattress is the biggest lever, not the only one.
