Best Cooling Mattress (2026)
Three mattresses that actually sleep cool. Tested by construction type, materials, and who each one works best for.
#1 Best Overall: Purple RestorePlus Hybrid
$2,399-$4,299 depending on size | Shop Purple RestorePlus
The Purple RestorePlus uses a proprietary gel grid with open channels that allow heat to flow away from the body rather than absorbing and holding it the way foam does. This is a structural difference, not a material additive — the grid physically cannot trap heat the way a foam surface does.
Hybrid coils beneath the gel grid add airflow through the core. The result is a mattress that can be noticeably cooler to sleep on than foam-based options.
Pros
- Open gel grid channels dissipate heat rather than absorbing it
- Hybrid coil core adds airflow through the mattress
- Good pressure relief at shoulders and hips for side sleepers
Cons
- Very expensive — starts at $2,399 for a queen
- Gel grid feel is unique and not everyone adjusts to it quickly
Best for: Hot sleepers who want the best temperature performance and are willing to pay for it.
#2 Best for Temperature Control: Saatva Solaire
$5,500-$9,500 depending on size (premium)
The Saatva Solaire is in a different category from the other picks here. It uses dual-zone air chambers that can be independently adjusted, giving each sleeper precise temperature and firmness control. If one partner sleeps hot and the other sleeps cold, this is the only mattress that solves both problems without compromise.
The price reflects the air chamber technology and Saatva's white-glove delivery and setup service. It is a significant investment but is used in clinical sleep labs for a reason.
Pros
- Dual-zone climate control — each side adjustable independently
- Best option for couples with different temperature preferences
- White-glove delivery and setup included
Cons
- Very expensive — $5,500 to $9,500 depending on size
- Requires ongoing maintenance compared to passive cooling options
Best for: Couples with different temperature preferences who want independent per-side climate control.
#3 Best Value Cooling Hybrid: Helix Midnight Luxe
$1,748-$3,248 depending on size
The Helix Midnight Luxe is a hybrid that combines gel memory foam with individually wrapped coils and a breathable TencelTM cover. It does not cool as aggressively as the gel grid of the Purple, but it sleeps significantly cooler than an all-foam mattress and costs less than either the Purple or the Solaire.
The zoned pressure relief in the Midnight Luxe also makes it a good choice for side sleepers who need both cooling and shoulder/hip pressure relief.
Pros
- Good balance of cooling and pressure relief
- More affordable than Purple or Solaire
- Breathable Tencel cover adds surface-level cooling
Cons
- Does not cool as aggressively as the Purple gel grid
- Premium tier of the Helix lineup — still $1,748+ for a queen
Best for: Hot sleepers who want good cooling performance at a more accessible price than the Purple.

Frequently Asked Questions
What makes a mattress cool?
Three main factors: the surface material, the core construction, and airflow. Gel grids (like Purple) have open channels that allow heat to escape rather than trapping it. Coil cores in hybrid mattresses allow more airflow than all-foam constructions. Breathable covers made of Tencel, eucalyptus, or open-weave cotton also help. Memory foam is the worst for heat retention because it conforms closely and blocks airflow.
Are memory foam mattresses hot to sleep on?
Traditional memory foam does sleep warm because it conforms tightly to the body and traps heat near the surface. Modern memory foams with gel infusions, open-cell structures, or copper infusions sleep cooler than older dense foams, but they still retain more heat than latex or hybrid coil mattresses. If you sleep hot, a hybrid or gel-grid mattress will be more effective than a gel-infused foam mattress.
Does mattress firmness affect how hot you sleep?
Slightly. A softer mattress allows more body contact with the surface, which can trap more heat. A firmer mattress keeps more distance between your body and the mattress, allowing some airflow. However, the bigger factor is the materials — a soft latex hybrid will sleep cooler than a firm memory foam mattress. Focus on construction and materials over firmness when optimizing for temperature.
What is the best mattress for hot sleepers?
The Purple RestorePlus Hybrid is the strongest performing mattress for hot sleepers because the gel grid's open channels actively dissipate heat rather than just slowing absorption. For couples with different temperature preferences, the Saatva Solaire has dual-zone climate control. Helix Midnight Luxe is the best value hybrid for hot sleepers who do not need the gel grid feel of Purple.
