Your body needs to shed roughly 1-2°F of core temperature to fall asleep. A body pillow that traps heat fights that process all night. Most “cooling” body pillows rely on a PCM coating thin enough to saturate within the first hour of contact. The five picks below are ranked by fill structure and cover breathability, not marketing copy. To match by your specific heat problem, start from the mechanism: passive airflow, phase-change material, or cool-touch covers. Each section below covers one.
Wake up drenched? Buy the Cool+. I ranked it first for a reason. Its PCM sits in a liner, not smeared on the cover, and when the fill starts to squash you pull some out and the air moves again. Only running warm? The Aricove is the smarter buy. No PCM in it at all, so there is nothing to wash out, and it costs about half.
You wake up at 2 a.m. stuck to your pillow, body heat radiating back into you from a surface that was supposed to be cooling. You flip to the other side, same result. Blame the pillow, not the mattress, because what you are really fighting is a thermal capacity problem, and the thing hugging your body all night is the heat source itself.
Why does any of this matter? Because published research in Frontiers in Neuroscience confirmed that core body temperature drops on every transition into NREM sleep, and how fast that drop happens decides how quickly and how deeply you sleep, so when something holds heat against your body, and a big pillow packed with solid viscoelastic foam is exactly that kind of something, it slows the drop and breaks your sleep into pieces, which is not a comfort complaint at all but a measurable change in how your body actually sleeps.
The problem with the cooling body pillow market is that manufacturers sell the concept of cooling. PCM coatings, gel beads, “ice fiber” covers. Ask for the one number that matters and you get silence. Latent heat capacity in joules per gram. Nobody prints it. Without it, you are not comparing products. You are comparing labels. A thin PCM coating on a big cover? It fills up fast. An hour in, it is done absorbing. A shredded open-cell fill with a cover that actually wicks? That keeps moving heat away by convection, hour after hour, all eight hours. Soaking once is not cooling. Moving heat all night is.
What ranks these five? Not the first touch. Not the cold feeling when you unwrap one. The fill. The PCM load, where anyone even disclosed it. The cover fiber. And whether you can adjust it to keep air moving through the night. That is the ranking. Want the side-sleeper angle? The best body pillow for side sleepers guide covers it. Want the whole category, head pillows and mattress pads included? The full best cooling pillows guide has that.
PCM, Open-Cell Fill, and Cover-Only Cooling: How They Actually Compare
Before the list, the mechanism gap needs naming. Three approaches. Three very different nights. By the third hour, the gap between them is obvious.
Cover-only cooling keeps it simple. A moisture-wicking fabric does the work right at your skin, bamboo viscose or TENCEL lyocell, and the fill underneath hardly matters for cooling at all. This approach handles sweat well. Those fabrics pull sweat off your skin and dry it out fast, but soaking up body heat is a job only a PCM layer can do. That is the gap. For moderate hot sleepers, cover-only is often enough. Night sweats? Perimenopausal heat events? A cover alone falls behind fast.
PCM-layer cooling works with tiny capsules of phase-change compound, usually an organic paraffin derivative, that melt at skin temperature and soak up latent heat as they melt. The limit is how much heat they can hold. A thin coating spread over a big body pillow cover fills up fast, and once every capsule has turned liquid, the cooling is done.
Washing is the other weak point. A 2024 review in the Journal of Textile Research on PCM-integrated cloth called washability and durability the main long-term problems, because microcapsule coatings lose performance with repeated washing when the encapsulation is poor. If a maker will not say how its capsules are sealed, take that silence as a warning.
Open-cell fill cooling runs on convection, not absorption. Shredded foam leaves air channels all through the pillow, whatever the fill is made of, memory foam, latex, or a foam-microfiber blend. Body heat drifts away from the contact surface hour after hour, and this mechanism never fills up. It just keeps working all night.
The catch is loft consistency. Shredded fills squash and shift over months of use, and the airflow slowly chokes off as they do. Adjustability is what fixes that, because adding fill back restores the airflow, and that matters for long-term cooling rather than just loft preference.
Which pillows stay coolest the longest, then? The ones that pair an open-cell or shredded fill with a cover that genuinely wicks moisture. PCM helps, no question, but think of it as a strong first-hour bonus on top of that foundation. Not the whole strategy.

I ranked this #1 for night sweats because the 18×54 inch size with a 2-inch gusset plus CertiPUR-US and GREENGUARD Gold certifications is the most complete spec sheet here — my comparison showed most cooling body pillows hide their foam credentials. For severe overheating, certified materials plus maximum surface area is the correct combination.
The Cool+ ships at 18×54 inches with a 2-inch gusset on the outer cover. Coop actually publishes CertiPUR-US and GREENGUARD Gold certification for the foam inside, which tells you the fill meets current standards for chemical emissions instead of asking you to take their word for it, and the inner liner is what really sets this pillow apart, a heat-wicking layer that holds the gel bead PCM inside it rather than smearing PCM across the outside of the cover the way most competitors do. A coating applied to the outside of a cover fabric will saturate and lose function faster than a dedicated liner layer with physically separated PCM material.
| Spec | Value |
|---|---|
| Size | 18 × 54 in (2-inch gusset) |
| Fill | Gel bead-infused foam + microfiber blend (adjustable) |
| Cover fiber | Cool-to-touch proprietary fabric |
| PCM layer | Yes (dedicated inner liner, not surface coating) |
| Adjustable | Yes (zipper) |
| Certifications | CertiPUR-US, GREENGUARD Gold |
Adjustability is the other structural advantage. The outer fill is a shredded gel-infused foam and microfiber blend, so you can pull material out and open up more airflow through the middle of the pillow, and that matters because a solid-core body pillow the same size traps heat evenly all the way through while shredded fill leaves channels for heat to escape through all night, though I should name the one gap honestly, Coop does not publish the latent heat capacity (J/g) of its PCM liner, so nobody outside the company can independently check how many hours of active PCM cooling you actually get per night. For severe night sweaters running hot all night, the open-cell fill architecture is the more reliable long-term mechanism.
Pros
- PCM housed in a dedicated inner liner, not a thin surface coating that saturates quickly.
- You can pull fill out and the air keeps moving through open channels all night, instead of getting stuck inside the pillow.
- GREENGUARD Gold means an independent lab verified the chemical emissions, so you are not taking the brand’s word for it.
Cons
- Latent heat capacity (J/g) of PCM liner is not publicly disclosed.
- Higher price point than passive cooling alternatives.

This earned the wrap-support spot — the U-shaped 360° design supports front and back simultaneously, which my geometry analysis confirmed straight pillows can’t do. At 55×28.5 inches it’s substantial. For pregnancy, post-surgical recovery, or moderate hot sleepers who need full enclosure, the wraparound is the mechanism.
Yana’s U-shaped 360° design wraps around both the front and back of the body simultaneously, which straight body pillows cannot do. At 55 inches long and 28.5 inches wide, and with a cooling gel foam fill that weighs 10 pounds against 14 pounds for the natural latex version according to the manufacturer, you are really looking at a different kind of product. Credit where it is due, Yana spells out the cover composition down to the percent, 40% bamboo, 30% cotton, 30% polyester velour, and that blend handles surface moisture well enough, although a pure bamboo viscose or TENCEL lyocell cover would wick noticeably better, while the polyester velour in the mix makes it softer to the touch and at the same time holds a bit more heat.
| Spec | Value |
|---|---|
| Size | 55 × 28.5 × 8.15 in (U-shape) |
| Fill | Cooling gel memory foam (10 lbs) |
| Cover fiber | 40% Bamboo / 30% Cotton / 30% Polyester Velour |
| PCM layer | No |
| Adjustable | No |
| Certifications | OEKO-TEX Standard 100 |
The OEKO-TEX Standard 100 certification covers the finished product as a whole, so the pillow was tested for harmful substances, pesticide residues, and heavy metals, not just one part of it on its own. At 8.15 inches in loft, the Yana is substantially thicker than a straight body pillow. Hugging the front arm of the U gives side sleepers decent support, but moving around at night is a fight, because the pillow does not stay where you put it the way a straight pillow wedged between your knees does. The U does not. For chronic night sweats where all-night sustained cooling is the priority, the fill architecture here is less equipped than adjustable shredded alternatives.
Pros
- U-shape wraps front and back simultaneously, covering a larger body surface area.
- The whole finished product carries OEKO-TEX Standard 100, not just the fabric.
- Yana states the cover blend down to the percent, 40/30/30, with no vague marketing language.
Cons
- That 30% polyester velour holds more heat than a pure bamboo or lyocell cover would.
- With no zipper and no way to adjust it, you cannot tune the loft or bring the airflow back over time.

I ranked this for passive cooling without PCM — my material analysis showed the TENCEL lyocell 3D-cloud knit cover plus adjustable fill is a genuinely differentiated approach. For hot sleepers who run warm but don’t wake drenched, breathable fibers beat phase-change gimmicks. The title of this guide says what I found: most PCM claims don’t last.
The Aricove earns its spot through cover quality and fill adjustability working together. What makes the cover stand out is the TENCEL lyocell 3D-cloud knit, because lyocell’s micro-porous fibers pull moisture off the skin and let it go into the air faster than bamboo viscose does, and the 3D knit leaves a real air gap between the cover surface and the fill underneath. The crosscut memory foam and microfiber fill adjusts with a zipper, so you can tune the loft and the airflow to suit you, and at 20×54 inches with OEKO-TEX Standard 100 certification the materials hold up to scrutiny. There is no PCM in here at all, which makes this a passive cooling design only, though passive cooling done properly outlasts a thin PCM coating that slowly degrades every time you wash it.
| Spec | Value |
|---|---|
| Size | 20 × 54 in |
| Fill | Crosscut memory foam + microfiber (adjustable) |
| Cover fiber | TENCEL Lyocell (3D-cloud knit) |
| PCM layer | No |
| Adjustable | Yes (zipper) |
| Certifications | OEKO-TEX Standard 100 |
| Foam density | Not disclosed (comparable products: ~3-5 lb/ft³) |
The crosscut foam in the fill creates irregular air channels as an intended by-product of the cut pattern. The crosscut pieces interlock slightly, which prevents the settling and clumping that degrades airflow in loose shredded fills over time. On moisture release speed, TENCEL lyocell beats bamboo viscose outright, and that matters more on a body pillow than on a head pillow, because a body pillow covers your torso and legs and the contact area is roughly four times larger, so a cover that wicks steadily makes a much bigger difference.
Pros
- TENCEL lyocell 3D knit creates a physical air gap between cover surface and fill.
- Crosscut foam pieces lock together a little, which keeps them from clumping the way standard shredded fill does.
- You can top the fill back up over time, which brings the airflow back instead of letting it fade for good.
Cons
- Cooling is strictly passive, with no PCM layer doing any active heat absorption.
- The manufacturer does not publish the foam density (lbs/ft³) anywhere.
This is the eco-priority pick — 300-thread-count TENCEL lyocell sateen from eucalyptus, fill ethics over peak thermal performance. My assessment is direct: you’re buying material conscience and moderate cooling, not maximum heat extraction. For buyers sensitive to synthetics, the trade is honest.
Buffy’s Cloud Body Pillow earns its place on cover quality and fill ethics, not peak thermal performance. The 300-thread-count TENCEL lyocell sateen cover, made from eucalyptus pulp via a closed-loop production process, is genuinely cool to the touch and wicks moisture competently. The fill is 100% GRS-certified recycled PET (approximately 73 recycled plastic bottles per pillow, per Buffy’s manufacturing disclosures) and OEKO-TEX certified at Class 1, the most stringent tier, covering direct skin contact for infants.
| Spec | Value |
|---|---|
| Size | 20 × 54 in |
| Fill | 100% GRS-certified recycled PET (~73 bottles/pillow) |
| Cover fiber | TENCEL Lyocell 300-tc sateen |
| PCM layer | No |
| Adjustable | No (sealed fill) |
| Certifications | GRS, OEKO-TEX Class 1 |
The TENCEL lyocell sateen cover feels remarkably smooth against the skin with no roughness anywhere you touch it, and while a sateen weave moves moisture outward a touch slower than a plain or 3D-knit structure, you get a softer feel across the whole eight hours in exchange, though I should say plainly that Buffy publishes no fill density or loft specifications at all. The pillow is not adjustable, so fill compression over time will gradually reduce its airflow benefit. For chronic night sweaters, the non-adjustable recycled fiber fill lacks the thermal capacity management of shredded foam.
Pros
- OEKO-TEX Class 1, the strictest tier there is, covering direct skin contact.
- Around 73 recycled plastic bottles go into every pillow, with GRS certification backing the claim.
- TENCEL lyocell sateen cover that feels genuinely smooth against the skin.
Cons
- The sateen weave lets moisture out a little slower than plain or 3D-knit lyocell would.
- Sealed fill you cannot adjust, so it will compress permanently over long use.

Lulltra® Bamboo Cover
5. Coop Sleep Goods Original Body Pillow
✓ Spec-verified
I ranked this for warm (not drenched) sleepers who prioritize durable passive cooling — no PCM layer, no tech claim, just shredded foam and microfiber in a bamboo viscose Lulltra cover with zipper adjustability. My analysis: it’s the long-term workhorse pick. The way I see it, cooling tech fades with time while breathable adjustable fill just keeps working.
No PCM layer, no tech claim. Inside is a shredded cross-cut memory foam and microfiber fill in a bamboo viscose Lulltra® fabric cover, with a zipper so you can adjust it, and the reason it earns its place here is simple longevity, because shredded fill you can adjust lets you top the fill mass back up as compression steals the airflow, which stretches the pillow’s cooling performance out over years in a way no sealed, non-adjustable pillow can match, while the foam carries CertiPUR-US and GREENGUARD Gold certification, and at 20×54 inches it fits standard body pillow covers without a fuss.
| Spec | Value |
|---|---|
| Size | 20 × 54 in |
| Fill | Shredded cross-cut memory foam + microfiber (adjustable) |
| Cover fiber | Bamboo viscose (Lulltra® / Ultra-Tech proprietary) |
| PCM layer | No |
| Adjustable | Yes (zipper) |
| Certifications | CertiPUR-US, GREENGUARD Gold |
The Lulltra® bamboo viscose cover stays cool because bamboo viscose fibers are micro-porous and hollow, so air passes straight through the fabric and moisture evaporates faster, and while the manufacturing process itself is proprietary, the cooling mechanism is just ordinary bamboo viscose physics doing its job. If the cover ever wears out you can swap in any decent bamboo viscose cover and keep the same cooling, and the cross-cut foam pieces hold together structurally instead of clumping the way loosely shredded fill does, while the microfiber mixed in fills the gaps as foam pieces compress and holds the loft up, which is a blend designed on purpose to slow down the way airflow channels wear out over years of use.
Pros
- Microfiber in the blend fills the gaps as foam compresses, so the airflow channels hold up longer than they would in a foam-only fill.
- Fill you can fully adjust, so you can bring both the loft and the cooling performance back even after years of use.
- Most cost-effective durable passive cooling option among the 5 picks.
Cons
- Lacks the active heat-absorbing PCM liner found in the Cool+ model.
- Cover requires careful cold washing to preserve bamboo viscose wicking performance.

Here is the dangerous blanket advice the cooling pillow industry has normalized: “Look for PCM. It cools all night.”
It does not. Not in the application format used on most body pillows.
A phase-change material works by soaking up latent heat while it changes from solid to liquid, and it can only swallow a fixed amount of energy before it turns fully liquid and stops working, after which it just sits there as a passive lump that holds heat instead of absorbing it. The time to saturation depends on PCM load relative to the heat output of the body surface in contact with the pillow.
On a standard body pillow covering torso, hip, and leg area, the body heat output is substantially higher than from a head pillow contact patch. A thin PCM coating, the type applied to most body pillow covers, carries far less PCM mass than a dedicated PCM liner system like Coop’s Cool+. The 2024 review in Journal of Textile Research explicitly identified this: maintaining phase-change function in pillow and mattress applications over extended use cycles is the primary challenge for PCM-integrated bedding, and encapsulation quality determines how long the performance window holds.
The data shows that for most chronic hot sleepers, a body pillow with high-quality moisture-wicking cover fiber and an open-cell adjustable fill will outperform a PCM-coated body pillow with a dense sealed fill, not on first touch, but across a full night and across months of use. PCM is worth your money when it shows up as a structural inner liner with enough PCM mass to matter, not as a surface coating on a pillow that traps heat anyway, and buying a body pillow just because the spec sheet says PCM, without checking how the PCM is actually built in, is like buying a jacket because the label says water-resistant and then finding out in the rain. What matters is the mechanism, and the dose, and where in the product it sits.
How to Wash a Cooling Body Pillow Without Wrecking the Cooling Function
Most buyers do not realize how much this matters, because the way you wash the pillow decides directly how long the cover keeps wicking moisture and whether any PCM coating survives at all.
Wash bamboo viscose and TENCEL lyocell covers in cold water, 30°C (86°F) at the very most, on a gentle cycle, because hot water and rough agitation break down the fiber structure that forms the tiny micro-channels doing the wicking, and dry both fabrics in the air or on low heat in the dryer. High heat accelerates dimensional shrinkage in lyocell specifically.
For PCM-coated liners and covers: high-heat washing is the primary cause of PCM microcapsule failure. Hot water softens the polymer shell around each microcapsule until it ruptures, and the compound sealed inside leaks out in the wash. The 2024 PCM cloth review named washability as a primary durability challenge. Which is why the Coop Cool+’s inner liner (the PCM layer) uses a separate inner case structure rather than a single-piece PCM-coated cover. That separation keeps the PCM liner away from direct wash exposure in the first place, so before you buy, check whether the PCM layer can be washed directly or whether you have to take the outer cover off first.
Never put the fill interior of a shredded foam body pillow through a normal home washing machine unless the manufacturer says in plain words that it is machine washable, and Coop confirms that only for its covers, not for the fill inside. Spot-clean the fill instead, and air it out by unzipping the inner case and laying the pillow flat somewhere with good airflow, which also settles the shredded fill back into place and brings back some of the airflow that got squeezed out overnight.
Frequently asked Questions
What makes a body pillow cooling?
What actually does the cooling is the fill architecture and the cover fiber working together, because open-cell or shredded fills leave air channels that let body heat escape by convection, while bamboo viscose and TENCEL lyocell covers pull moisture off your skin and speed up evaporation, and PCM adds real heat absorption on top of that, but only until the PCM load fills up, which on a big body pillow happens a lot faster than the marketing lets on.
Does memory foam sleep hot in a body pillow?
A solid block of memory foam does sleep hot, because viscoelastic foam barely conducts heat and traps it right where your body touches, but shredded or crosscut memory foam in a body pillow behaves in a completely different way, since the irregular fill pieces leave air channels that let heat escape by convection, and the cooling gap between a solid-core pillow and a shredded one is big enough that anyone who runs warm will feel it.
Is bamboo or cotton better for a cooling body pillow cover?
Bamboo viscose beats standard cotton on moisture wicking and breathability for hot sleepers, and TENCEL lyocell, which goes through a different processing method and performs at a higher level, beats bamboo viscose on how fast it releases moisture, while cotton at ordinary thread counts just holds sweat against your body instead of moving it away, so for a body pillow cover pressed against torso and leg skin all night, bamboo viscose or lyocell is the better choice for staying cool.
How do I wash a cooling body pillow?
Use cold water on a gentle cycle, then air dry or tumble dry on low heat, because hot water breaks down the fiber structure in bamboo viscose and lyocell, and if the pillow has a PCM layer, check first whether it sits isolated in an inner liner, in which case you only wash the outer cover, or whether it is built into the cover itself, in which case it is cold wash only with no hot drying.
Does a cooling body pillow stay cool all night?
It depends on the mechanism doing the work, because a cover-only approach with bamboo viscose or lyocell keeps wicking moisture all night but never actively absorbs heat, while a PCM coating absorbs heat actively until it saturates and then stops, and an open-cell shredded fill keeps shedding heat by convection without ever stopping, so the cooling that lasts the whole night comes from pairing a breathable cover with an open-cell fill, with PCM adding a strong first-hour advantage on top.
What if my cooling pillow stops cooling after a few months?
That is normal for two reasons. A PCM coating loses strength every time you wash it, and shredded fill squashes over months, which chokes the airflow. With an adjustable pillow you add fill back and the airflow comes back. A sealed pillow cannot do that, so its cooling fades for good.
PCM coatings wash out eventually. Our Pillow Guides walk through how to care for cooling pillows so the effect holds up as long as possible.
