Based on specs, cover materials, and owner feedback, we rank the DreamCloud Premier Rest as the best overall cooling mattress for its phase-change cover and breathable coils. For hot sleepers wanting deeper cooling, the GhostBed Luxe is a strong alternative.
Sleeping hot is one of the most common complaints owners raise about foam mattresses, so we compared the cooling claims of popular models against their actual cover materials, foam composition, and coil construction. We focused on features that genuinely move heat away from the body, such as phase-change covers, gel infusions, breathable coil layers, and open-cell foams, rather than marketing language alone.
None of these picks were tested in our own lab. Instead, our ranking is built on published specifications, available certifications, and recurring themes in verified owner reviews. We pay close attention to where owners agree and where opinions split, since temperature regulation depends heavily on body type, room conditions, and bedding.
DreamCloud Premier Rest
The DreamCloud Premier Rest pairs a cashmere-blend cover with a quilted gel-foam layer over individually wrapped coils. The coil base allows air to circulate, which helps the bed sleep cooler than all-foam alternatives. Its medium-firm feel suits a wide range of body types and sleep positions.
How we research and rank
We do not take payment for placement and we do not physically test products. Rankings come from manufacturer specifications, material certifications (CertiPUR-US foam, OEKO-TEX textiles), and thousands of aggregated owner reviews analyzed for durability, heat retention and sagging.

Frequently asked questions
What actually makes a mattress sleep cooler?
Cooling comes from materials that move heat and air rather than trap them. Coil layers, breathable covers like cotton or Tencel, gel infusions, and phase-change covers all help. Hybrids with coils generally sleep cooler than all-foam beds because air circulates through the base.
Are hybrid mattresses cooler than all-foam ones?
In most cases, yes. The coil layer in a hybrid lets air flow underneath the comfort layers, which carries heat away. All-foam beds can still feel cool at the surface with gel or phase-change covers, but they tend to retain more warmth deeper down.
Do phase-change cover materials really work?
Phase-change covers absorb body heat and feel cool to the touch when you first lie down, and many owners notice the difference. The effect is most pronounced at the surface and can lessen over the night. Pairing one with a hybrid base usually gives the most consistent results.
Can bedding make a cooling mattress sleep hot?
Yes. Thick mattress protectors, heavy comforters, and synthetic sheets can block airflow and trap heat, undoing a cooling mattress. Breathable cotton or bamboo sheets and a thin, breathable protector help the mattress perform as intended.
How long should a sleep trial be for a cooling mattress?
A trial of at least 90 to 100 nights is reasonable, since it takes a few weeks to judge temperature across different room conditions. Several picks here offer a full year, which gives you time to see how the bed performs through a season change.
The verdict
Across specs and owner feedback, the DreamCloud Premier Rest stands out as the best overall cooling mattress thanks to its breathable coil base and cashmere-blend cover. Hot sleepers who want the strongest surface cooling should look at the GhostBed Luxe, while side sleepers will likely be happier with the zoned, pressure-relieving Helix Midnight Luxe. Budget shoppers can still sleep cooler with the gel-infused Zinus Green Tea pick.
