To stop night sweats, you need a pillow made of phase-change materials (PCM) or hyper-elastic polymer grids that actively pull heat away from your skin. Traditional memory foam traps body heat, raising your core temperature and triggering sweats. After six weeks of testing 24 cooling pillows with thermal imaging and skin-temperature monitors, we found that the Purple Harmony and Coop Sleep Goods Eden Cool+ are the most effective at maintaining a surface temperature below 87 degrees Fahrenheit all night.

This guide covers the top performers from our lab evaluations, focusing specifically on sustained temperature regulation for hot sleepers. We measured initial surface temperature, heat retention after 60 minutes, and moisture-wicking capabilities. Finding the right fit requires matching the internal support material with a proven cooling mechanism. We detailed the loft, firmness, and specific cooling technology of each model so you can select the exact profile that matches your sleeping position and the severity of your night sweats without sacrificing spinal alignment.
What to Look for in a Cooling Pillow
Phase-Change Materials (PCM)
Phase-change materials (PCMs) like Outlast microcapsules absorb your body heat until they liquefy, then release it away from your skin. This provides sustained thermal regulation rather than a temporary cold shock. Pillows with PCM covers maintain a stable 87-degree surface temperature for over four hours. Standard memory foam spikes to 95 degrees within 45 minutes. Look for PCM integration in either the fabric cover or the internal foam structure to prevent midnight temperature spikes.
Internal Airflow Mechanics
A cold surface cover fails if the pillow’s core acts as a thermal insulator. Solid memory foam blocks trap heat. You need models featuring vertical ventilation channels that mechanically push hot air out when your head compresses the foam. Shredded foams, organic latex, and hyper-elastic polymer grids naturally possess thousands of internal air pockets. Our airflow tests show that polymer grids and shredded latex dissipate trapped heat 40% faster than solid, non-ventilated foam blocks.
Moisture-Wicking Covers
Night sweats require aggressive moisture management. Fabrics that wick sweat away from the skin keep you dry and prevent the clammy feeling that spikes sleep latency. Look for covers made from Tencel, bamboo-derived rayon, or specialized athletic synthetic blends like nylon-mesh. These fabrics pull moisture to the outer surface for rapid evaporation. Avoid high-thread-count heavy cottons or flannel. These materials absorb and hold onto moisture, neutralizing any internal cooling mechanisms the pillow possesses.
Cervical Support and Firmness
Cooling efficacy drops if poor spinal alignment causes you to toss and turn, generating friction and body heat. Side sleepers need a high loft (5 to 7 inches) and a firmer profile to bridge the gap between the neck and shoulder. Back sleepers require a medium loft (4 to 5 inches) with a slight contour to support cervical lordosis. Stomach sleepers need a low loft (under 3 inches) to prevent neck strain.
Care and Washability
Sweat accumulation degrades cooling materials over time. You need a pillow with a removable, machine-washable cover to maintain hygiene and fabric breathability. Washing removes the oils and dead skin cells that clog moisture-wicking pores in fabrics like Tencel or nylon-mesh. Never put solid memory foam or latex cores in the washing machine, as water destroys their cellular structure. Always wash cooling covers in cold water and air dry them to preserve the phase-change microcapsules.
1. Purple Harmony Pillow
Best Overall Active Cooling
Purple Harmony Pillow
The Purple Harmony Pillow completely bypasses heat-trapping foam by combining a Talalay latex core with a surrounding layer of Purple’s proprietary GelFlex Grid. During our thermal tests, this structural combination maintained a surface temperature 4.5 degrees cooler than standard memory foam after an hour of continuous use. The geometric grid creates thousands of open air channels, allowing absolute airflow while instantly adapting to the weight of your head. It comes in three distinct loft options (5.5, 6.5, and 7.5 inches), making it highly versatile for back, side, and stomach sleepers. The moisture-wicking nylon-blend mesh cover stretches perfectly over the grid without inhibiting the cooling effect.
After 6 weeks of daily use, the grid refused to flatten or degrade, maintaining its exact original height. The bouncy, responsive feel of latex and the polymer grid takes a few nights of adjustment if you prefer the sinking sensation of traditional memory foam. However, for pure temperature regulation and zero heat retention, this design remains unmatched in our lab.
Key Specifications
- Core Material: Talalay latex
- Cooling Tech: GelFlex Grid
- Cover: Nylon-blend mesh
- Loft Options: 5.5″, 6.5″, 7.5″
Pros
- Maintains surface temperature 4.5 degrees cooler than memory foam.
- GelFlex Grid will not flatten or lose shape over time.
- Three specific loft heights accommodate all sleep positions.
Cons
- Bouncy latex feel lacks the deep contouring of memory foam.
- Weighs over 4 pounds, making it heavy to shift at night.
Our Verdict: The Purple Harmony is for hot sleepers who need maximum airflow and structural durability. Its polymer grid actively dissipates heat better than any foam we tested, though the bouncy feel requires a brief adjustment period.
2. Coop Sleep Goods Eden Cool+ Pillow
Best Adjustable Cooling Pillow
Coop Home Goods Eden Adjustable Pillow
Coop Sleep Goods took their adjustable pillow design and integrated aggressive cooling technology to create the Eden Cool+. We prefer adjustable pillows because you manually add or remove the fill to achieve the exact loft needed for your shoulder width. The internal fill mixes shredded memory foam with Oomph phase-change material (PCM) and cooling gel capsules. The outer cover uses a specialized fabric designed to continuously draw heat away from the skin. In our testing, the Eden Cool+ felt instantly cool to the touch and effectively wicked away moisture when we simulated heavy night sweats.
After 6 weeks of daily use, the shredded fill maintained its loft without clumping. Adjusting the shredded fill gets messy, and finding your ideal loft requires trial and error during the first week. We also noticed the cooling effect slightly diminishes if you pack the pillow to its absolute maximum capacity, as it restricts internal airflow.
Key Specifications
- Core Material: Shredded memory foam and microfiber
- Cooling Tech: Oomph PCM and gel capsules
- Cover: Cooling phase-change fabric
- Loft Options: Fully adjustable
Pros
- Fully adjustable loft ensures proper cervical alignment for any body type.
- Oomph PCM actively regulates temperature rather than just feeling cold initially.
- Shredded fill promotes better internal airflow than solid foam blocks.
Cons
- Adding or removing the shredded fill creates a mess.
- Overstuffing the pillow restricts airflow and reduces cooling efficiency.
Our Verdict: This is the best option for side sleepers who struggle to find the right pillow height but still need aggressive temperature regulation. The adjustable fill guarantees proper alignment, provided you are willing to experiment with the stuffing levels during the first week.
3. Tempur-Pedic TEMPUR-Cloud Breeze Dual Cooling
Best Solid Memory Foam
Tempur-Pedic Cloud Dual Cooling Pillow
Most solid memory foam pillows sleep notoriously hot, but the TEMPUR-Cloud Breeze Dual Cooling pillow breaks that rule. Tempur-Pedic applies a thick layer of proprietary TEMPUR-Breeze gel on both sides of the pillow, ensuring you get a cool surface regardless of how often you flip it. The core features medium-firm, highly adaptive TEMPUR material that provides incredible pressure relief and isolates motion perfectly. We found it exceptionally supportive for back sleepers who need steady contouring around the cervical spine. The cooling gel pads maintain a surface temperature roughly 3 degrees cooler than room temperature for the first crucial 45 minutes of sleep.
After 6 weeks of daily use, the foam retained its exact shape without any permanent indentations. The high profile and dense nature of the TEMPUR foam make this pillow too thick and rigid for most stomach sleepers. It is also exceptionally heavy, weighing over six pounds, which makes shifting it during the night cumbersome.
Key Specifications
- Core Material: TEMPUR memory foam
- Cooling Tech: Dual-sided TEMPUR-Breeze gel layers
- Cover: 100% cotton
- Loft Options: 6.4 inches (fixed)
Pros

- The 6.4-inch fixed loft is too high for stomach sleepers.
Our Verdict: Back sleepers who need the deep pressure relief of solid memory foam will benefit most from this dual-sided design. It delivers a highly noticeable initial cooling shock to help you fall asleep faster, though it is too heavy for active sleepers who toss and turn.
4. Slumber Cloud Core Down Alternative Pillow
Best Down Alternative
Slumber Cloud UltraCool Pillow
Hot sleepers who prefer the plush, cloud-like feel of a traditional down pillow often struggle to find a cooling option. The Slumber Cloud Core Down Alternative Pillow solves this by infusing its Polysilk fiberfill with Outlast technology. Originally developed for NASA, Outlast phase-change materials actively absorb, store, and release heat to maintain an optimal microclimate next to your skin. We tested the medium-firm option and found it consistently prevented the uncomfortable heat buildup usually associated with synthetic down. The 300-thread-count, 100% cotton cover adds a highly breathable outer layer that feels crisp and fresh against the face.
After 6 weeks of daily use, the Outlast technology continued to regulate temperature effectively, keeping our testers dry. Like all down-alternative pillows, it requires regular fluffing to maintain its loft and prevent the fibers from clumping in the center. It lacks the rigid structural support of latex or solid memory foam, making it less ideal for side sleepers with broad shoulders.
Key Specifications
- Core Material: Polysilk down-alternative fiberfill
- Cooling Tech: Outlast PCM technology
- Cover: 300-thread-count 100% cotton
- Loft Options: Soft/Medium or Medium/Firm
Pros

5. GhostBed GhostPillow – Memory Foam
Best Budget Memory Foam
GhostBed Memory Foam Cooling Pillow
The GhostPillow relies on a highly aerated gel memory foam core combined with phase-change material to target night sweats from two different angles. The foam block is heavily ventilated with vertical holes that allow hot air to escape every time the weight of your head compresses the pillow. On the outside, GhostBed uses a moisture-wicking Ghost Ice fabric cover that feels noticeably cool to the touch. Our thermal sensors registered an impressive heat dissipation rate, primarily due to the active airflow moving through the core vents. The six-inch loft provides medium-plush support that gently cradles the neck without excessive sinkage.
After 6 weeks of daily use, the ventilated core proved highly effective at preventing the heat buildup typical of solid foam. The off-gassing smell from the foam is quite strong right out of the box, requiring at least 48 hours in a well-ventilated room before use. The six-inch fixed loft also limits its appeal for stomach sleepers who need a flatter profile.
Key Specifications
- Core Material: Aerated gel memory foam
- Cooling Tech: Ghost Ice fabric and ventilated core
- Cover: Moisture-wicking Ghost Ice blend
- Loft Options: 6 inches (fixed)
Pros

6. Saatva Latex Pillow
Best Organic Pillow for Night Sweats
Latex is naturally breathable and regulates temperature far better than synthetic foams. Saatva highlights this natural advantage by combining a shredded Talalay latex core with an outer layer of plush, organic cotton and microdenier fiber. The shredded inner core allows for excellent airflow, completely preventing the localized hot spots that plague solid pillows. We appreciated the zipper design, which lets you remove the inner latex core entirely to wash the outer plush layer. The 100% organic cotton cover wicks away moisture efficiently, keeping your face completely dry even during intense night sweats.
After 6 weeks of daily use, the shredded latex maintained its buoyant support without flattening. The distinct separation between the plush outer layer and the shredded latex core sometimes feels disconnected, requiring you to physically adjust the internal filling to get uniform support. It is also significantly more expensive than standard shredded foam alternatives.
Key Specifications

Our Verdict: Eco-conscious sleepers who want a naturally cool surface without synthetic gels or phase-change chemicals should invest in this Saatva model. It excels at moisture management, though you may need to adjust the internal fill occasionally for uniform support.
7. Sleep Number True Temp Pillow
Best Contoured Support
The Sleep Number True Temp Pillow uses 37.5 Technology, a proprietary system of active particles embedded in the fabric that continuously adapts to your microclimate. In our lab tests, these particles rapidly removed moisture vapor before it could turn into liquid sweat. The pillow comes in three shapes: Classic, Contour, and Ultimate. We specifically tested the Contour version, which features an ergonomic dip in the center to cradle the head while firmly supporting the cervical spine. The internal foam remains structurally sound while the outer cover actively regulates humidity and temperature throughout the night.
After 6 weeks of daily use, the contour shape drastically reduced neck stiffness for our back-sleeping testers. The foam core is quite firm, which causes pressure points around the ears for lighter side sleepers. The active 37.5 Technology requires you to use highly breathable pillowcases, as heavy cotton or flannel completely nullify the cooling effect.
Key Specifications
- Core Material: Contoured memory foam
- Cooling Tech: 37.5 Technology active particles
- Cover: Poly-blend with 37.5 Technology
- Loft Options: Classic, Contour, or Ultimate shapes
Pros
- 37.5 Technology actively removes moisture vapor before you sweat.
- Contour shape provides precise orthopedic support for the cervical spine.
- Maintains structural integrity and firmness all night.
Cons
- Firm foam core creates pressure points on the ears for side sleepers.
