Most Comfortable Pillows for Side Sleepers 2021

Dive into the details on all these pillows below.

Editor’s Pick

Testing the Casper foam pillow on my back.

Casper Foam Pillow

My favorite pillow this year is the Casper Foam Pillow, a great pick for back and side sleepers. 

This is Casper’s first-ever foam pillow, and features a three-layer design that incorporates high and low-density foams for a balanced feel. Essentially, the soft outer layers provide  cloud-like comfort, while the firm inner layer serves as a support system. And, as I mentioned, this unique construction is great for both back and side sleepers!  

Strict side sleepers will be glad to know that the foam layers in this pillow comfortably cradle the head and neck, relieve pressure at the shoulders, and promote neutral spine alignment throughout the night. Plus, it’s medium-firm feel prevents it from going flat while you slumber

Best Foam Pillow

The Bear pillow.

Bear Pillow

The Bear Pillow is my favorite foam pillow for side sleepers this year. I especially like it because in addition to being comfortable, it sleeps super cool.

From the cover fabric to the internal fill, every part of this pillow was made with hot sleepers in mind. First, it’s covered in Phase Change Material, which is an icy-cool textile used to make fabric feel cool to the touch. And, frankly, when I first tested this pillow, I thought it had been refrigerated! Next, it’s filled with airflow-boosting ventilated foam and capped with mesh panels that increase breathability. This is one of the coolest pillows I’ve ever tested, and I heartily recommend it to side sleepers who run hot!

In addition to sleeping cool, this pillow is hypoallergenic and has a nice medium-firm feel. Plus, it should conform nicely to your head and neck when you’re on your side.

Best Pillow for Combination Sleepers

The Saatva Dreams pillow.

Saatva Pillow

As a combination sleeper, I can honestly say that the Saatva pillow supports me in every position (which is pretty rare, in my experience). It features a unique dual-layer design wherein an inner pillow is tucked inside an outer pillow, and they complement each other to offer balanced support

The outer pillow is filled with a down-alternative that feels soft to the touch, while the core of the pillow is filled with shredded Talalay latex. The latex offers a springy feel that serves as the support system, while the down-alternative makes this pillow fluffy and foldable. 

As I said, this pillow does a great job of supporting me in every position, but side sleepers are bound to enjoy the way this pillow-in-pillow design maintains its lofty build and medium-firm feel

Best Pillow For Neck Pain

Eli & Elm Side Sleeper pillow.

Eli & Elm Pillow

The Eli & Elm Side Sleeper pillow is a great pick for folks who need help alleviating neck pain. I should start by saying that this is the pillow I use at home and, despite its rather specific title, I can tell you that it’s great for back sleeping too! 

It’s filled with a proprietary blend of latex and down-alternative, which combine to create a plush-yet-supportive feel. And while it is amply stuffed into a pretty lofty build, sleepers have the option to adjust the internal fill to their liking. 

But the main reason this pillow is great for neck pain is that it’s got a boomerang-shaped, ergonomic design that conforms to the exact contours of your head, neck, and shoulders. I find this to be ideal for side sleeping, but back sleepers should feel free to lay right in the middle of the pillow and lean against the lofty sides.

Best Organic Pillow

The Birch Living pillow.

Birch Living

Side sleepers looking to go green should definitely consider the eco-friendly Birch Living pillow. 

From the cover fabric to the internal fill, this entire pillow is made from organic materials. The cover is made from 100% organic cotton, which means no genetically modified cotton seeds or synthetic pesticides were used to make it. It’s filled with a mix of ethically sourced wool, and natural shredded Talalay latex. 

In my experience, the combination of wool and Talalay latex made for a fluffy, medium-firm feel that kept the loft high enough for side sleepers. Plus, pure wool is thermoregulating, which means it adapts to your body’s temperature. It’s also worth noting that pillows made from natural materials tend to do a great job of maintaining shape throughout the night, and I definitely found that to be the case with this one! 

If you’re looking for an organic pillow that won’t go flat while you snooze, I suggest you check my full Birch Living pillow review for all the details.

Best Memory Foam Alternative Pillow

The Nolah pillow.

Nolah AirFoam

Side sleepers who love a foam feel but want to avoid deep sinkage might want to take the Nolah AirFoam pillow for a spin. 

Filled with Nolah’s proprietary foam, this pillow was crafted to offer springy support. Typically, foam pillows offer a deep sink and a slow response to pressure, but Nolah’s foam feels a bit like latex! It’s lightweight, buoyant, and has a rather quick response to pressure

Side sleepers who prefer to rest on top of their pillow instead of sinking down into it might really like this pillow. It’s got a lofty 4-inch profile and medium-firm feel, both of which promote neutral spine alignment in the side sleeping position. 

One of the (literally) cool parts of this pillow is that the cotton cover fabric has been infused with Phase Change Material, a special textile used to make fabric feel icy-crisp against the skin. If you often find yourself flipping your pillow mid-slumber in order to sleep on the “cool side,” rest assured that this entire pillow feels cool and soothing to the touch

Best Faux Down Pillow

The faux down GhostPillow.

GhostPillow Faux Down

If you love the feel of down, but are looking for a hypoallergenic and/or animal product-free option, the GhostBed Faux Down pillow might be the right pillow for you. Made with a microfiber gel fill, this pillow has the same soft and squishy feeling as down. It has a soft, removable outer cover that’s easy to wash, and a 100% cotton inner cover that’s nice and breathable.

I particularly like this pillow for side sleepers because it has a high loft of 7 inches — side sleepers need a taller pillow to keep their neck in line with their shoulders, which promotes a neutral spinal alignment. As a side sleeper myself, I often prefer to sleep with a pillow between my legs to prevent my knees from rubbing together, and I found the GhostPillow to be quite comfortable in this position too.

Best Pillow for Shoulder Pain

The Layla Kapok pillow.

Layla Kapok

Next up is the Layla Kapok pillow, and this big ol’ bedtime companion is one of my top picks for a few reasons. 

Firstly, it’s filled with shredded memory foam and Kapok (which is a natural tree fiber), which combine to offer a cozy balance of softness and support. The memory foam makes the pillow conform to pressure, while the Kapok boosts the fluffy factor! Meanwhile, copper threads are woven into the cotton cover fabric in order to draw heat away from your head, making for a cooler snooze

But the thing that really makes the Layla ideal for side sleeping is its exceptionally lofty profile of 7-inches. A high-lofted pillow serves to hold your head in neutral alignment with your spine, and supports healthy posture throughout the night. This is definitely one of the loftiest pillows I’ve ever tested, which might make it particularly compatible with those looking to alleviate shoulder pain. 

If you’re looking to relieve a little pressure at the shoulders, I suggest resting the top of your shoulder on the base of the pillow when you hit the hay. The dense-yet-fluffy combination of materials will conform to your shoulder, and keep it from bearing the brunt of your body’s weight.

Best Memory Foam Pillow

Tempur-Pedic TEMPUR-Cloud Pillow

Tempur-Pedic TEMPUR-Cloud

If you’re a side sleeper who can’t get enough of that moldable memory foam feel, the TEMPUR-Cloud Breeze pillow might be perfect for you. 

Filled with one piece of Tempur-Pedic’s proprietary memory foam, this pillow conforms to your head and neck, offers a super slow response to pressure, and lets you deeply sink into the material. Not to mention, it’s got a medium-firm feel and a lofty 6-inch profile, which makes this pillow ideal for side sleeping. 

And if you’re worried about memory foam’s tendency to trap heat, don’t sweat it. Two cooling gel pads keep this pillow from warming up while you slumber, and make both sides of the pillow feel cool to the touch.

If you’re a side sleeper looking for a cooler way to sleep, I can’t recommend this pillow enough. If you’re not a side sleeper but you love memory foam pillows, check out my full Tempur-Pedic pillows review to see how the Breeze compares to the rest of Tempur-Pedic’s pillow options!

Best Latex Pillow

Testing the Purple Harmony pillow on my back.

Purple Harmony

If you’re looking for a bouncy latex pillow with a super quick response to pressure, look no further than the Purple Harmony pillow. 

A mix of Talalay latex and the brand’s proprietary Purple Grid combine to offer some springy support that should position you on top of the pillow rather than in it. If you avoid memory foam because you feel trapped by its slow response to pressure, the Purple Harmony might be right up your alley. 

Hot sleepers might like to know that every part of this pillow’s construction is ventilated for improved airflow. But my personal favorite feature of the Harmony is its resilience. In my experience, it tightly conformed to the contours of my head and neck, relieved pressure at my shoulders, and still returned to its original shape every morning.

How to Choose the Best Pillow for Side Sleeping

Now that you have a few pillows in mind, let’s discuss the methodology behind my picks. Of course, a lot comes down to personal preference, but there are some key factors to consider when hunting for the perfect side-sleeper pillow:

Loft

When I’m shopping for a side-sleeper pillow, the very first thing I pay attention to is the loft, or height, of its profile. The general rule of thumb is that side sleepers need a pillow with a higher loft (of at least 4-inches) in order to maintain a neutral spine alignment and relieve pressure at the shoulders.

If you’re shopping online, scroll through the brand’s website to find the “dimensions” info in order to determine the exact loft of a pillow. Again, the loft should be at least 4-inches high. But if you’ve taken advantage of a brand’s trial period and are testing the pillow at home, ask yourself these questions:

  • Is this pillow lofty enough to keep my spine in a straight line, or does my head sink below my shoulders?
  • Is this pillow so lofty that it cranes my neck upwards, out of alignment with my spine?
  • Is this pillow’s loft providing enough pressure relief for my shoulders?

Remember — your pillow’s most important job is to promote healthy posture, and a side-sleeper pillow should be the right height to hold your head in neutral alignment with your spine. For more info about healthy sleeping posture, be sure to check out my guide to picking the best pillow for your position. And if you’re not sure what loft you’d prefer, check out some adjustable loft pillow options.

Firmness

The next thing I look at is firmness. In my opinion, loft and firmness go hand in hand. Why? Well, think of it this way: A high-lofted pillow won’t stay lofty for long if it’s too soft to maintain its shape. And the softer a pillow is, the more it’s going to compress under the weight of your head.

That’s why side sleepers need a pillow with a firmer level of support! A pillow with a medium-firm, firm, or even extra firm rating is going to do a better job of maintaining its loft, which serves to keep your head aligned with your neck and spine. So look for firm pillows that don’t compress too far under your weight while you shop.

Support

Loft and firmness level work hand in hand to create support. It’s crucial for side sleepers to find a pillow that offers them appropriate neck support. You don’t want to crane your neck up or down as you sleep, as this can lead to pain over time. A pillow that properly supports your head and neck will help you achieve a neutral spinal alignment, which can help prevent neck and back pain. Generally, a high loft and firm feel will provide appropriate support for side sleepers.

Pressure Relief

While you want a supportive pillow, you’ll also want one that offers a bit of pressure relief. If you pick a pillow that’s too firm, you could end up with a sore ear or stiff neck. Make sure you’ll feel comfortable with the amount of cushion your pillow is offering around the side of your head.

Keep in mind that a pillow that offers soft support might let your head and neck sink below your shoulders. This will actually increase pressure around your shoulders, which can feel uncomfortable over time. So a pillow that offers firm support will actually offer more pressure relief in your shoulder area.

Shape

While you can feel comfortable on a standard shaped pillow regardless of your preferred sleep position, some brands offer alternatively shaped pillows specifically designed for side sleepers. If you struggle with neck pain, you may want to consider an ergonomically designed side sleeper pillow. These pillows often feature a u-shape that fits around your shoulder and reduces pressure around your neck. If that appeals to you, take another look at the Eli & Elm pillow above!

Cooling

A breathable pillow is important for all kinds of sleepers. If you’re a hot sleeper you may want to opt for pillows made of materials like latex or gel-infused memory foam, which tend to sleep cool. You might also want to consider pillows made with covers that encourage airflow. Take a look at our best cooling pillows to learn more about choosing a breathable pillow option.

Wash Care

You’ll also want to consider wash care when choosing a pillow for side sleeping. Many of the best side sleeping materials (like memory foam) are spot clean only. I’d recommend opting for a pillow with a removable and machine washable cover as a way to keep wash care simple.

Fill

Speaking of materials, choosing the right fill for your pillow is quite important for side sleepers! I’ll go over how the different pillow fill materials perform for side sleepers in the next section, but first I want to take a minute to talk about whether or not to choose an adjustable fill as a side sleeper.

It’s not mandatory, but choosing a pillow with an adjustable fill allows you to manipulate the loft and firmness in order to fit your exact needs. Again, this isn’t necessary, but you may find that being able to customize the internal fill of your pillow helps you reach your perfect comfort zone.

For example, if you find your pillow to be too lofty or firm, simply unzip the cover and remove as much internal fill as you like. In my experience, it can take a little trial and error in order to find the perfect level of support but, trust me, a good night’s sleep is worth the effort.

Choosing the Right Pillow Materials for Side Sleeping

The pillow fill material you choose has a big impact on how your pillow feels. While the right loft and firmness level for side sleepers are fairly universal, fill materials can impact more specific preferences. For example, do you want a pillow that feels warm or cool? Bouncy or moldable? There’s a wide world of pillows out there, and it’s worth it to take every factor into consideration in order to unlock your best sleep potential!

So, let’s go over a few different pillow materials:

Memory Foam

Memory foam pillows have a slow response to pressure and offer a lot of body-contouring. In my opinion, dense memory foam pillows with a high loft are some of the best options available to side sleepers. Memory foam has a tendency to trap heat, but choosing a gel-infused foam or a pillow that uses a shredded memory foam fill (instead of a solid block of foam) can help mitigate these heat trapping tendencies.

Polyfoam

Polyfoam is a little more responsive than memory foam, and is often less dense. If you’re looking for a foam feel but don’t like a lot of body-contouring, a polyfoam pillow could be a nice option for you. But keep in mind that polyfoam is often a little less durable than other foams, so your pillow may not last as long.

Latex

Latex pillows are naturally cooling and hypoallergenic. They have a very bouncy feel that sleepers who like to feel “on top of” their pillow should like. Latex offers less sinkage than most other pillow materials, so it could be a supportive option for many side sleepers. Check out my best latex pillows roundup to learn more about this material.

Buckwheat

Buckwheat pillows are filled with buckwheat hulls and naturally feel very firm. If you prefer fluff and softness, this is not the pillow material for you. But buckwheat pillows are often great options for side sleepers, as they’ll stay supportive for a long time. In fact, a high-quality buckwheat pillow can last up to 10 years! These pillows can also be very helpful with combatting neck or back pain. Learn more in my best buckwheat pillows roundup.

Feather

Feather pillows are cooling, fluffy, and soft. They’re a little denser than down or down alternative pillows, which can make them more moldable. You can find flat or overstuffed feather pillows, so side sleepers after fluffiness and moldability should be able to find a feather pillow that meets their loft and firmness needs. Check out my best feather pillows roundup to see a few options.

Down / Down Alternative

Down and down alternative pillows often feel soft, fluffy, and luxurious. Down alternative pillows offer a similar fluffy feel, but are more eco-friendly. You also don’t have to research manufacturing and sourcing to be sure that your new down alternative pillows are cruelty-free!

Since down compresses more easily than other pillow materials, I recommend it more for back sleepers and stomach sleepers than side sleepers. However, a firmer down option can also work for side sleeping. My best down pillows and best down alternative pillows roundups include some great side sleeping options.

How to Position Your Pillows as a Side Sleeper

Before you drift off to sleep, consider positioning your pillows like this to improve your sleep posture and prevent pain.

  • When you lie down on your pillow, make sure your ears are in line with your shoulders and your chin is neutrally positioned. Tucking your chin against your chest or curving your neck down can lead to pain over time.
  • Place a second pillow between your knees and lift them up towards your chest. This helps keep pressure off your knees and hips, which means your back will stay straighter at night.
  • Make sure your arms and hands are below your shoulders. Some people find hugging another pillow near their waists can make this more comfortable. You can also try using a body pillow as a between the legs and under the arm solution.

Avoiding Neck Pain

If you struggle with neck pain, you should try to stick to the tips above to reduce pain. If you’ve replaced your old pillows and are maintaining the sleep posture suggested above, but still struggle with neck pain, you might want to consider training to sleep on your back. Back sleeping is often best for maintaining a healthy posture and avoiding pain. You might also want to check out some of the best pillows for neck pain.

FAQs

What kind of pillow should a side sleeper use?

In general, side sleepers need a pillow with a lofty profile of at least 4-inches in order to maintain healthy posture throughout the night. Additionally, pillows with a firmness rating of medium-firm or firm are typically best suited to the side sleeping position.

Do side sleepers need a soft or firm pillow?

Side sleepers typically need a pillow with a firmer feel in order to maintain neutral spine alignment throughout the course of the night. A firmer feel can also prevent your pillow from losing its shape over time.

When should you replace your pillow?

A good rule of thumb is to replace your pillows every 1-2 years. You’ll notice your pillow become less supportive (or even lumpy) over time, which is also a good sign that it’s time to refresh your bedding.

What type of pillow is best for side sleepers with neck pain?

A firm, lofty, pillow with a u-shaped design that accommodates your shoulder and supports your neck is often a good way to reduce neck pain if you sleep on your side.
