The 9 best thin pillows in 2024 - editor-approved for your perfect sleep

Pillows are not a one-size-fits-all product, and the type of pillow you prefer will often depend on your sleep position. If you sleep on your side, the best thin pillows will keep your spine aligned for the comfiest of snoozes as they won't prop your head up too much in bed – though side, back and combination sleepers are likely to find two thin pillows the perfect arrangement. 

Shopping for the best pillows can be tricky, and finding the best thin pillows can be easier said than done. Retailers favour fluffier pillows, and many bedding brands market the best pillows as being plush. But thicker pillows may not meet your needs. The right pillow for you should help you rest at the right height, and laying on a pillow with too much loft could over-arch your neck. If you're struggling to sleep and often wake up with neck aches, a thin pillow or two could solve your sleepy head needs.

To help find the best thin pillow for you, we've done the research and reviewed some of the top pillows that are flatter in profile. Including adjustable pillows perfect for combination sleepers, guest beds, or those who like their pillows to all be the same – but have a partner who prefers a thicker fill – these are the 12 pillows that passed our sleep test.  

You'll find more details below on how our home editors tried, tested, and (re)evaluated the best pillows. We've made sure there are options for all sleep styles and budgets so you can get your best sleep yet

The quick list

The best thin pillow overall

Image 1 of 2

Simba sells some of the best mattresses around, so it's no surprise that their pillows are also supremely comfortable. The Hybrid pillow (one of just two Simba pillows) has two layers—an outer cover made from cotton, and an inner cover, filled with squishy blue foam 'Nanocubes'. Because of this, when you first receive the pillow, it will seem fairly plump and thick. All you need to do to create a thinner pillow is to remove as many of the cubes as you want—if you want a low elevation, they suggest removing around eight to 10 handfuls. Handily, Simba also provides a small white bag to store the extra cubes in. 

During testing, this pillow gave us one of the best night's sleep we've had in recent years—even after removing some of the cubes for a thinner design, it still felt plush and incredibly comfortable when sleeping on both our back and our side. It also provided a brilliant mix of support and comfort. While some pillows can feel too firm to be supportive, this pillow perfectly treads the line between the two, and our heads, necks, and shoulders felt supported all night. We also woke up with no aches and pains, and none developed during our week or so of testing, either.

The Hybrid pillow is also made using Simba's well-known Stratos fabric, which is designed to keep air flowing through the pillow and acts as a temperature regulator. And during our nights of testing, we found this function worked well (though not flawlessly)—the pillow didn't heat up and we stayed fairly cool all the way through until the morning.

The best breathable thin pillow

Woolroom's Deluxe Washable Wool Pillow is one of the smartest picks we tried. It's filled with 580g of traceable British wool, and you can add and remove it to achieve your required thickness. We did find after prolonged testing that this flattened out after a month or so of use, so we recommend fluffing up the filling every now and again to keep the pillow as thick as you'd like it. 

Another huge benefit of opting for this wool pillow is that it holds the Allergy UK Seal of Approval. Naturally hypoallergenic, wool and the organic cotton cover are less vulnerable to breeding dust mites. Plus, the pillow is machine-washable, which means you'll find it easier to keep clean than many of the pillows on this list. 

The unbleached 200tc organic cotton cover does lean more beige than white, which could show through pure white pillowcases and make your bedding look a little dirty. We tested this pillow alongside the brand's linen bedding and we did find that the unbleached colour showed through a little. However, alongside the linen sheets, the breathable materials will ensure that warm sleepers are able to adapt between seasons. 

The best customizable thin pillow

The Pancake Pillow adjustable layer pillow strives to meet the needs of all sleepers. If you've yet to find your ideal height, this customizable solution may be perfect for you. Each of its six layers is removable, allowing you to experiment until you find your favorite stack of 'pancakes'. This flexibility makes it one of the best pillows for neck pain on the list too. 

No matter how thin you choose to go, the puff gel microfibre filling guarantees your head will have a soft place to land. If you like your thin pillow to still be fluffy and comfortable, like the best hotel pillows, this is a great option.

Overall, the Pancake Pillow can take the stress out of buying online—the retailers boast that it's impossible to accidentally buy the wrong size, as you can adjust the pillow to your preference. And unlike the Co-op Home Goods pillow above, there's a lot less mess involved, as you only have to remove layers and not actual fill.

The best memory foam thin pillow

Bluewave Bedding is a great company if you're after a flatter pillow, since they're well aware that thin pillows can often be preferred for sleepers who don't want to sleep too high up in bed. Their memory foam gel pillow is available in three loft sizes — Slim, Super Slim, and Hyper Slim.

Their thinnest option, the Ultra Slim, comes in at just two-and-a-half inches tall, but still boasts a soothing gel filling and the rounded edges of traditional pillow shapes. Not only can this design accommodate your thin-pillow needs. It's also said to help reduce snoring and back pain. Customers raved that this pillow is a great option for stomach sleepers and for those who sleep with their arms under their heads.

Bluewave has made sure to counteract the heating effects some memory foam can have by adding temperature-regulating gel particles into the material—making it cool to the touch for more comfortable sleep. one of the best memory foam pillows on this list, too.

The best cooling thin pillow

After trying the Casper foam pillow in the middle of a heatwave we had to award it as one of the best cooling pillows. Thin in profile too, without that plush profile that your head sinks into, it's the best thin pillow that will keep the hot heads sweat-free, even during summer. 

Casper is known for selling some of the best memory foam mattresses on the market, so there's no surprise their foam pillows pass the sleep test too. We've found it would suit most sleep styles, as it is thinner than most memory foam pillows for front sleepers, but it also offers enough support to keep side and back sleepers happy too. It doesn't lose its fill or shape over time either, but best of all, it sleeps cool. Need we say more? 

At a reasonable price, it seems like a hard pillow to beat. But the off-gassing smell caused by synthetic fibers did put our tester, and many other customers off from sleeping on this pillow for the first few nights.

The best wool thin pillow

Unlike the adjustable pillows on our list, this is a truly thin(ner) pillow that should work perfectly for those who don't like to feel too high when they sleep. Its shallower profile is ideal for whatever sleeping position you prefer, but especially for back and side sleepers. During testing, we slept largely on our side and found that the Soak & Sleep Wool pillow was comfortable and supportive without being thick and oversized. Unlike some thin pillows we've tried, we didn't wake up with a sore neck and shoulders—in fact, we felt very well rested.

One of the serious draws of this pillow is also the fact that its filling is 100% Mitchell wool, straight from New Zealand. Wool has a number of benefits; it's hypoallergenic, moisture-wicking, and a brilliant temperature regulator—and this all proved to be true during testing. While we often wake up with a sniffly nose, our breathing was clear and easy come the morning. And for those who like a cool pillow, this option was fantastic (perhaps even better than the Simba), as it stayed almost cold the entire night, which provided very welcome relief during an unseasonably warm November evening.

The only slight drawback to this pillow was the fact that it did make a slightly crinkly sound whenever we moved about during the night, which could be disruptive to light sleepers, or light sleeping partners. However, we reckon this could be easily solved by using a thicker pillowcase—you'll probably want to avoid the best silk pillowcases with this option.

The best thin pillow for stomach sleepers

Blissbury works to guarantee that you'll have the perfect pillow no matter where you go. Their super-thin Stomach and Back Sleeping Pillow is also one of the best travel pillows, not just because of its size, but because it has a handy little carrying case too, and bends easily to fit into it.

This slim sleeper is just a couple of inches of gel and memory foam. The filling is equipped with small ventilation holes that help to regulate body temperature as you sleep. On top of that, its cover is made with bamboo and polyester. These natural materials help to reduce moisture and create a cool sleeping experience

However it's worth noting that this is one of the very thinnest pillows on our list, so may not be the right pick for you if you're a side sleeper or need a little more loft.

The best plush thin pillow

The Beckham Hotel Collection Bed Pillows are always at or near the top of Amazon's best-selling pillows. They're also among the most reasonably-priced—and considering that you get two of them, that equates to one of the lowest prices-per-pillow we've found.

These hotel-quality pillows are quite plush but not too lofty. Back sleepers tend to find them comfortable and supportive for their head and neck. However, side sleepers may find these pillows don't cradle their neck and shoulders well enough in this position, and stomach sleepers might want something a little less fluffy.

Anyone who suffer from allergies will appreciate the hypoallergenic down alternative fill of the Beckham Hotel Collection Bed Pillows. We do wish it came with a clear warranty, but if the hundreds-of-thousands of 5-star Amazon reviews are anything to go by, you'll be receiving fantastic value here.

The best affordable thin pillow

This pillow from Kally Sleep is another adjustable option, meaning it's a solid choice for those who want to experiment with the height of their pillow a little bit. It comes with four inner sleep pads to create a unique sleeping experience. Consider it the Goldilocks of thin pillows; if it's not quite thin enough, or too thin, you can simply stack up the inserts or remove some to create the right height – even switching it up from night to night if you want to. This pillow also comes with a 14-night trial, so you can return it during this time if it isn't right for you.

We first tested the pillow with just one insert. But we found this was almost too thin, and left too much gaping within the cover. So even if you are after a thin pillow, we'd advise placing two inserts inside the cover at a minimum. After this, the pillow was much more comfortable and was still flat enough that our head and shoulder didn't feel overly elevated. In fact, this Kally Sleep Pillow was one of the best options we tested for allowing our entire spine to feel in total alignment. During the night, the pillow also felt firm, so our heads and necks felt well supported.

When it comes to quality, this option (including the inserts) didn't feel quite as high-end as the Simba, for example. But this is reflected in the price, which is much more affordable. For a pillow you can customize entirely to fit your preferences, we'd say the Kally Sleep Adjustable pillow offers brilliant value for money. One of our other gripes was that you'll need to store any leftover inserts somewhere, as it doesn't come with a storage bag; but don't let this put you off the pillow. 

How we tested the best thin pillows

More than just sleeping on the job, the best pillows have been tested in our own homes for support, quality, and how well they live up to comfort claims. They've been slept on for at least five consecutive nights, washed, and rested on again in order to replicate real-life use. Our review process includes a focus on: 

• Comfort: This is the number one factor we test for; what else is a pillow for if not for comfort? When sleeping on each pillow, and upon waking in the morning, we judged how comfortable it felt to lay our head on, and how soundly we slept on the pillow. Just like with a new sofa, one of the top priorities is being able to cozy up on your pillow without feeling like you're constantly needing to adjust it.
• Support: Similarly, we judged how supported our heads and necks felt by the pillow throughout the night. Even thin pillows need to support our spinal alignment, to ensure we aren't plagued by aches and pains throughout the day, and that we don't cause any long-term damage. A big part of this testing aspect is how firm (or not) a pillow is. While we all have our own personal preferences – some prefer an ultra-soft, cloud-like experience, while others want a super-firm pillow. The key is that your pillow doesn't leave you in pain the next morning, and makes your upper body feel supported.
• Value-for-money: Finally, one of the most important parts of any new purchase is whether it's worth the money or not. Everyone has their own budget, but no one wants to pay over the odds for something that just isn't worth the price. In our assessments of the best thin pillows, we've considered whether higher-price pillows are worth the splurge, whether lower-price options are good enough quality to recommend – and whether they're actually a steal for the price.

What to consider when choosing between the best thin pillows

There are a few things to think about when deciding which thin pillow is best for you. These include: 

• Your sleeping position: When choosing the best thin pillow, you should "acknowledge whether you’re a back, stomach, or side sleeper, and assess your own physiology when determining the proper thickness," says Stephen Light, co-owner of Nolah Mattress. Front and back sleepers are usually better suited for thin pillows than side sleepers — who actually benefit from thicker pillows since they'll need something that can comfortably fit between their ear and shoulder. If you tend to switch positions, consider an adjustable pillow so you can change things up when needed.
• Material and filling: Filling material is another component to keep in mind when buying a thin pillow. Alex Savy, Certified Sleep Science Coach and the Founder of SleepingOcean recommends memory foam for sleepers who like their pillow to cradle their head and neck, while latex and polyfiber offer more buoyancy. Hot sleepers, meanwhile, should seek cooling materials such as gel-infused foam or kapok, or a company's own cooling technology. If the pillow mentions cooling technology, it is generally a good option for hot sleepers.
• Whether you want adjustable or not: As demonstrated above, you generally have two options if you're on the hunt for a thin pillow; a naturally flatter option, or an adjustable pillow. Adjustable pillows can be incredibly helpful if you're not sure how flat you want your pillow and want the option to experiment. But some prefer the feel of naturally flatter pillows – so when choosing the best thin pillows for you, consider your priorities here.
• Cost and trial periods: Believe it or not, pillows can get pricey. So when you're shopping for your next thin pillow, make sure you keep a budget in mind. Some of the best pillows will cost anywhere from $50/£40 to $100/£80. If possible, look for a pillow that offers a trial period of at least 30 days too – though any trial period is better than none. This will give you time to adjust to the pillow before determining whether or not it's right for you.
