The Casper Hybrid Pillow with Snow Technology is the coolest pillow I have ever tested. That’s why it takes my pick for the best overall cooling pillow. Not only is the machine-washable cover cool to the touch but the inside of the pillow is made with perforated poly foam, polyester fibers and gel. It uses what Casper calls Snow Technology, which has phase-change material that remains temperature-neutral around your head and neck and allows for airflow.  

The pillow is soft yet supportive, and I like how my head sinks a little into the poly foam — but not too far. In terms of firmness, I would say it is medium, and when you press your hand into the material, it returns to its original shape a bit faster than memory foam does. So no need for fluffing. The Casper Hybrid Pillow will support back, side and combination sleepers (those that switch between positions at night).

Sleeping position(s): Back, side and combination 

Pros:

• Cool to the touch; coolest pillow I tested 
• Soft, machine-washable cover 
• Four layers of foam, fiber and gel with Snow Technology 

Cons:

• Over $100 for one pillow
• Not for those who don’t like foam          

GhostBed is known for its comfortable cooling mattress, and its cooling Gel Memory Foam Pillow is no different. It’s made with a perforated gel memory foam core, a layer of phase-changing materials, an inner aerated mesh and a cover that’s truly cool to the touch. I like how the pillow conforms to my head and neck and feels cool on my face. 

Compared to other cooling and memory foam pillows on the market, the GhostPillow Gel Memory Foam Pillow is very affordable — and not to mention, most pillows that claim to be cooling aren’t as cool to the touch as GhostBed’s. I think it’s a great value and can support back, side and combination sleepers.

Sleeping position(s): Back, side and combination 

Pros:

• Cool to the touch 
• Machine-washable cover
• Affordable; GhostBed often has sales 

Cons:

• Not for strict stomach sleepers
• Cooling cover is only on one side  

The Brooklyn Bedding Luxury Pillow isn’t just the winner for the best cooling memory foam pillow — it’s also the best pillow for all sleeper types. There are two lofts available: high and low. A high loft is great for side sleepers, and a low loft is meant for back and stomach sleepers. Its hexagon-patterned cover is cool to the touch and can be removed and washed. The cover extends to the other side, but the hexagon side is the coldest. 

The memory foam itself is perforated, and the top is infused with copper. This natural mineral helps to fight against mold, allergens and dust mites. I’m a huge fan of memory foam, and I like that this Brooklyn Bedding pillow allows me to switch between sleeping positions comfortably. Also, Brooklyn Bedding often has deals, so you can usually grab this pillow for under $99.  

Sleeping position(s): Stomach and combination

Pros:

• Cool to the touch 
• Machine-washable cover
• Great for all sleeper types 

Cons:

• Over $100 for one pillow
• On the thinner side

The Nest Easy Breather is one of the more supportive pillows on this list. The cover is cool to the touch, and the pillow is filled with shredded foam. If the pillow arrives too firm or too high for you, simply remove some of the fillings and fluff it back up. When it was filled to its maximum, I found that it supported my neck and head from sinking into the surface — which is great for side sleepers who don’t like the sinking feeling of memory foam. 

I prefer the Nest Easy Breather to be a little less filled so I can comfortably switch from my side to my back. Also, I wouldn’t consider this a comfortable pillow for strict stomach sleepers, so you may have to remove almost all the fill. Check out the best cooling pillow for stomach sleepers instead. 

Sleeping position(s): Back and side

Pros:

• Cool to the touch
• Machine-washable cover 
• Adjustable loft  

Cons:

• Not for strict stomach sleepers
• Not for those who like to sink a little into pillows 

I consider the Purple Harmony pillow to be a mini-version of the Purple Mattress. Both products contain a GelFlex grid layer that’s unique to Purple. This feature is flexible, supportive and slightly molding like memory foam. The Purple Harmony pillow also has a Talalay latex (a natural latex sourced from rubber trees) core that is perforated for airflow and won’t trap your body heat. 

The machine-washable mesh cover is slightly cool to the touch but less cool than the Casper, GhostBed or Brooklyn Bedding pillows. With the Purple Harmony, its inside materials are more important and cooling than the cover. This pillow will support back and side sleepers comfortably.     

Sleeping position(s): Back and side  

Pros:

• Cool to the touch
• Unique honeycombed-pattern grid
• Soft, machine-washable cover 

Cons:

• Expensive
• Not everyone will like the latex-grid feel 

The Bear Pillow is another great pillow for back sleepers. Its cover is cool to the touch and made with what Bear calls Double Ice Fabric. At both ends of the pillow is a mesh that allows for more airflow. It’s also hypoallergenic and helps to stop mold, bacteria and dust mites. At its core, the Bear Pillow is made with a hybrid foam, which I consider halfway between bouncy latex foam and slow molding memory foam. I think it’s right down the middle of too firm and too soft. It’s also supportive enough for both back and side sleepers.        

It should be noted that you can’t wash the Bear Pillow cover. Spot-clean only and use a light, breathable pillowcase.  

Sleeping position(s): Back and side

Pros:

• Cool to the touch
• Hypoallergenic
• Contains perforated, hybrid foam   

Cons:

• Not for strict stomach sleepers
• Not for those who don’t like the bouncy feel of latex foam
• Expensive at MSRP

If you’re a side sleeper, you should look for a pillow that’s high enough to keep your neck aligned during the night. It’s best to avoid using a pillow so soft that your head sinks because you’ll likely wake up with neck pain. The Layla Kapok is great for side sleepers because it’s high and firm enough to keep you from overextending your neck. The pillow is filled with shredded memory foam for optimal airflow, and it can even be adjusted by taking out the filling. If you are a back sleeper, just take out a bit of the Layla Kapok pillow’s filling, and it should be low and soft enough for you.

The fibers used in this pillow are lighter and more ventilated than cotton or wool, giving it that cooling sensation. As a side sleeper, I especially like the feel of this pillow. I like to sink a little bit, which the Layla Kapok allows, but it’s also supportive enough that I don’t hurt my neck during the night.    

Sleeping position(s): Back, side and combination 

Pros:

• Adjustable (remove filling to your liking)
• Plush and supportive 
• Soft, machine-washable cover

Cons:

• Not cool to the touch
• Not for strict stomach sleepers

Pillows for stomach sleepers are sometimes hard to come by. They must be supportive and low enough that you don’t overextend your neck at night. The Cozy Earth Silk Pillow is a great example of a pillow that supports the neck and is low enough for strict stomach sleepers. Made of bamboo fabric and 100% mulberry silk, this Cozy Earth pillow uses the lightest and coolest materials to keep you from overheating at night. And you can feel it. I love how soft it feels to the touch. 

While the cover isn’t cool like the Casper, GhostBed or Brooklyn Bedding pillows, the Cozy Earth Silk Pillow makes up for it with quality. Its premium materials prevent pilling, making the pillow last a long time. 

I think this pillow would also be comfortable for back and combination sleepers.    

Sleeping position(s): Stomach and combination     

Pros:

• Filling is 100% mulberry silk
• Cover is 100% bamboo fabric 
• Only made with breathable materials 

Cons:

• Not cool to the touch
• Most expensive 

Coop Sleep Goods has recently become popular for its cooling products. Its Eden Pillow continues to top lists of cooling pillows, and if you thought that pillow was cool — it got even better. The Coop Eden Cool Plus Pillow is the newer, cooler version of the Eden Pillow. This pillow has a similar cool-to-the-touch cover and now features a heat-wicking inner liner, a gel layer and shredded gel-infused memory foam. The filling is Greenguard Gold and CertiPur-US certified. One side claims to be cooler and firmer than the other, but I didn’t feel that when testing.   

One of the best features of this pillow is that it’s adjustable. It comes with extra filling, as well as an option to pull the filling out. Make it as firm or soft, high or low as you desire. I filled mine with a little more than the way it came. I like that the memory foam contours and lets you sink a little into the pillow, regardless of how much you fill it.  

Sleeping position(s): Back and side

Pros:

• Cool to the touch 
• Adjustable and hypoallergenic 
• Machine-washable cover 

Cons:

• Not for strict stomach sleepers
• Not for those who don’t like to sink a little into pillows 

If you’re conscientious about your bedding and where the material comes from, look no further than Birch. This brand is organic, eco-friendly and natural. Birch’s Organic Pillow is made with a 100% organic GOTS-certified cotton cover, and while it isn’t cool to the touch, it’s breathable. The core is made of a 100% organic cotton outer layer filled with shredded latex. That core is then wrapped with 100% organic, GOTS-certified wool that helps to wick away moisture. 

I love that this pillow doesn’t feel lumpy, and it would be very supportive for back and side sleepers.

Sleeping position(s): Back and side     

Pros:

• GOTS and Eco-Institut certified
• Contains Fair Trade cotton
• All materials are natural and organic 

Cons:

• Not cool to the touch
• Over $100 for one pillow

The Sleep Number True Temp Pillow comes in three shapes: classic, contour and ultimate. I tested the classic for this review, which is best for back sleepers. If you’re a side sleeper, I recommend the contour and all sleeper types should like the ultimate, as it can be customized to fit any sleeper. Regardless of the shape, the Sleep Number pillow is cool to the touch and contains 37.5 technology, which refers to material embedded with volcanic minerals that wick away moisture.

The fill is 100% foam, and I think it feels like a poly foam that isn’t too soft. It supports your head and neck without sinking too much into the foam.     

Sleeping position(s): Back   

Pros:

• Cool to the touch
• Comes in classic, contour and ultimate shapes
• Soft, machine-washable cover 

Cons:

• Not for strict stomach sleepers
• Side sleepers should choose the contour shape 

The softest and thinnest pillow on this list belongs to the Saatva Latex Pillow. It’s available in two lofts: standard and high. Back and stomach sleepers should go with the standard loft, while side and combination sleepers should choose the high loft. For this review, I tested the standard loft. 

This pillow reminds me of a luxury hotel pillow that isn’t overstuffed with filling. It is made with a cotton cover (that isn’t cool to the touch) and filled with certified organic cotton, plush, down-like fibers and a shredded natural latex core. The material is breathable and hypoallergenic, which fights bacteria, mold, mildew and dust mites. The cotton cover is also machine washable.  

Sleeping position(s): Back, stomach, side and combination

Pros:

• Shredded natural latex core
• Machine-washable, Fair Trade Certified cotton cover
• Available in standard and high lofts 

Cons:

• Not cool to the touch
• Not for those who don’t like thinner pillows 

The Nolah Adjustable Shredded Foam pillow is my favorite of the honorable mentions. This pillow is made of shredded foam that can be taken out and adjusted to your liking. Its cover is soft, machine-washable, and made of Oeko-Tex-certified bamboo blend fibers. The best part is that one box comes with two queen-size pillows. 

I found the pillow to be between the soft Helix pillow and the firmer Marlow pillow below. You sink into it, but not too much. My only complaint with this pillow is that it’s not cool to the touch, and some sleepers might find it too lumpy.  

Sleeping position(s): Back and side

I sleep on Brooklinen sheets every night, so I’m a big fan of the brand. This was the first Brooklinen pillow I’ve ever tested. The Marlow Pillow is made of memory foam and polyester fiber, and the outside cover is made of 100% cotton. You can’t remove any filling to adjust the firmness to your liking, the pillow comes with two zippers (one at the top and one at the bottom) that do just that. You won’t notice a huge difference.

I found the Marlow Pillow to be more supportive than a pillow made with shredded memory foam. You won’t sink, but it might be too firm for some sleepers. 

Sleeping position(s): Back and combination

The Lagoon Otter Pillow is the definition of versatile. The fill is made with shredded gel-infused memory foam, and the cover is polyester and bamboo. While the pillow arrives prefilled with foam, there’s extra foam available and an extra pouch for any fill that you wish to take out. The pillow feels soft, but it’s not cool to the touch. 

Lagoon claims that this pillow is for all sleeper types, but my testing didn’t agree. It is great for back and side sleepers, but to sleep comfortably on your stomach, you would have to take out nearly all the fill. For the price and effort, it might be worth it to get a pillow designed for stomach sleepers.

Sleeping position(s): Back and side

The Sijo Support Pillow is for those who like pillows that are firmer, bouncy and supportive. It isn’t for memory foam lovers — like myself. The inside is made entirely of perforated Talalay latex foam, and the outside shell is made of a blend of eucalyptus fibers. The pillow is Oeko-Tex Standard 100 certified, hypoallergenic and made of environmentally sustainable materials.

It isn’t cool to the touch, but the pillow is made of all the right temperature-neutral materials. My head hardly sinks at all on top of this pillow. It’s also a light pillow for how dense it feels.  

Sleeping position(s): Back and side
