1. Amerisleep Comfort Classic Pillow

amerisleep comfort classic
The Amerisleep Comfort Classic Pillow is our recommendation for side sleepers because it’s the perfect medium loft. The pillow is filled with Amerisleep’s Bio-Pur®—a plant-based memory foam with an open-cell structure for ultimate breathability.

Many reviews point to this pillow being great especially for side sleepers because it has a 6” loft, or thickness, so you won’t have to constantly fluff it or fold it to properly support your head. A supportive pillow like the Comfort Classic should keep your neck level with your shoulders and promote healthy spinal alignment. If you are a side sleeper, it might take more than a pillow to give you optimal comfort. When looking for your next mattress, consult our article on the best mattresses for side sleepers.

Amerisleep Comfort Classic Pillow Highlights

  • Stuffed with eco-friendly, pressure-relieving foam.
  • Ventilated airways in the foam make the Comfort Classic breathable and cooling.
  • Designed especially for back and side sleepers.

2. Amerisleep Dual Comfort Pillow

Like the Amerisleep Comfort Classic Pillow, the Dual Comfort Pillow is made with their advanced plant-based memory foam, Bio-Pur®. Instead of 100 percent petroleum oils, this foam is partially made with plant-based oils. Amerisleep’s construction method makes Bio-Pur® eco-friendly, non-toxic, and highly responsive.

The Amerisleep Dual Comfort Pillow offers sleepers two firmness options. One side of the pillow is soft and compresses easily when pressure is applied. The other side if firmer. Side sleepers typically prefer the firmer side because it is strong enough to prevent the head from sagging and forcing the spine out of alignment. Back sleepers rest well on the softer side because it offers just the right amount of sinking to keep the head and neck in line with the shoulders.

This pillow has a soft, airy cover to prevent heat-trapping. The surface of the foam in the Dual Comfort Pillow is embedded with cooling channels that increase air circulation so the pillow is always cool and inviting. The Dual Comfort Pillow is available in two different lofts—a 5-inch loft and a 6-inch loft—and two different sizes—queen and king. 

Amerisleep Dual Comfort Pillow Highlights

  • Dual-sided comfort offers sleepers a firm side or a soft side
  • Cooling air channels allow heat to dissipate quickly
  • Designed especially for back and side sleepers.

3. Amerisleep Flex Pillow

The filling of the Amerisleep Flex Pillow is specially designed to suit any sleep position. Inside the pillow, hundreds of MicroFlex cushioned mold to the curves of the head and neck to keep you supported and resting in a safe sleep position. You can reshape this pillow night after night to fit your specific needs.

Since Amerisleep’s MicroFlex cushions are shredded, warm air is able to escape quickly, preventing the pillow from becoming too warm and uncomfortable. The soft cover the Flex Pillows is also made with an airy, ventilated fabric that ensures proper air circulation, so you can sleep undisturbed throughout the night.

The Amerisleep Flex Pillow comes with a 10-year warranty. It is also available in two different sizes—queen and king. 

Amerisleep Flex Pillow Highlights

  • Hundreds of MicroFlex cushions allow you to change the shape of the pillow
  • Highly responsive material moves with the body
  • Designed to support most sleep positions, including back, side, and combination sleepers

An extra-firm pillow may seem counterintuitive for side sleepers, but numerous customer reviews stated the extra support was perfect for their neck pain. A firmer pillow can also withstand lots of use.

The pillow comes wrapped in a thick bamboo cover made with Kool-Flow®, a micro vented fabric that breathes and stretches easily. Snuggle-Pedic uses their Kool-Flow® material to prevent an uncomfortable night of sleep. Customer reviews commented on this pillow’s durability and plentiful shoulder support.

Special Concerns for Side Sleepers

When it comes to side-sleeping, flat pillows are a pain in the neck— literally! Sleeping laterally with or without your arms under the pillow presents some potential issues.

Supporting your head and neck are the most important things your pillow does for you, whether you realize it or not. If your neck is arched unnaturally, your spine will follow, leading to back, neck, and shoulder pain.

Side-sleepers should take certain things into consideration when shopping for a pillow:


Pillow loft, or thickness, tells you how much space the pillow will put between you and your mattress. Stomach sleepers typically choose pillows with a low loft, and back sleepers prefer high lofts. It only makes sense that side sleepers feel most comfortable on a medium loft pillow.

Loft affects the way your neck and head feel as you sleep. If your pillow is too short and unsupportive, your head and neck will sink, forcing you to adjust the pillow, your sleep position, or both all night. Conversely, if your pillow is too firm or thin, you could wake up with aches and pains all over.

Medium loft pillows usually fall between 3 and 5 inches thick. Anything lower or higher than that may be troublesome for side-sleepers.

Some pillow models have gussets for extra loft, which are simply fabric panels sewn onto the sides of the pillow.

Cover Fabric

Side and stomach sleepers are more likely to press their faces into their pillows and because of that, they will need to take special care in choosing a pillow with a breathable, soft cover.

If you suffer from allergies, consider a hypoallergenic pillow made using latex, memory foam, Kapok, Tencel, or bamboo.

Paresthesia (Pins and Needles)

That numb, tingly feeling you get when you’ve put too much pressure on a limb is known as paresthesia. It’s harmless as long as you readjust and prompt circulation to flow again. Side sleepers are prone to pins and needles in their arms and sometimes legs, especially if they sleep with their arm or arms under the pillow.

This is when loft comes into play again— a medium loft pillow will keep the pressure the pressure from your head off your arm(s), thus avoiding waking up with sleeping, numb limbs.

Shoulder Pain

For side sleepers avoiding pain, choose a pillow made with supportive materials like foam, latex, or buckwheat. We only suggest side sleepers use down or down alternative pillows if they are marketed as medium or medium-firm, since this will feel a bit more comfortable and offer extra support.


Nope, we’re not talking about wrinkles on your pillowcase (although that might be a concern for you, too!). Side and stomach-sleepers are more prone to facial wrinkles than back sleepers, and while a pillow can’t necessarily prevent this, the pillowcase can. Try using a silk pillowcase to potentially avoid premature wrinkling.

Advantages to Side Sleeping

Side-sleeping is one of the healthiest sleep positions for a multitude of reasons. If you sleep on your stomach or back, try teaching yourself to sleep on your side by practicing it a few times a week or when taking naps.

Sometimes knowing the benefits can convince us to break a habit more than anything else, so let’s go over a few of them:

Spinal alignment: Good posture is not just for the daytime— posture that doesn’t strain your back or neck while you sleep can be the key to managing pain. Your pillow and mattress will help a lot in this regard— additionally, your sleeping position should not strain your body at all. Side-sleeping allows your spine to rest naturally and your neck to lie straight.

Reduces acid reflux: If you suffer from GERD (gastroesophageal reflux disease) or acid reflux, sleeping can stir up the symptoms because you’re laying down. During the day, you’ve got gravity to keep the stomach acid at bay, but at night, it’s much trickier. Sleep on your side to ensure your esophagus is higher than your stomach, keeping acid down where it belongs.

Reduces snoring: If you sleep on your back, this can cause the base of your tongue and the soft palate to collapse against the back wall of your throat, leading to snoring. Sleeping on your side can prevent this from happening.

More comfortable if you’re pregnant: As we mentioned earlier, sleeping on the side is not only more comfortable for pregnant women, but it’s also healthier for the baby.

Good for organs and heart health: Sleep Junkie recommends sleeping on the right side whenever possible because studies show it’s the optimal position for heart health.

Optimal brain health: New studies have revealed that side-sleeping can allow your brain to more efficiently remove waste that contributes to diseases such as Alzheimer’s and Parkinson’s.

Best and Worst Pillow Types for Side Sleepers

Pillows these days are much more than a pillowcase stuffed with fluffy cotton. Different pillow types are best for different sleeping styles. Let’s go over the best and worst for side sleepers:


Buckwheat: Buckwheat pillows are filled with buckwheat hulls for substantial support and moldability. They’re a good option for side sleepers thanks to their medium-high loft and support.

Down: Down pillows are filled with the soft inner plumage of ducks or geese. These pillows are typically ideal for stomach sleepers since they’re very soft, moldable, and tend to flatten after some use. Side sleepers may be comfortable on down pillows depending on their construction.

Memory foam: Memory foam is an excellent option for side sleepers because it conforms closely and offers both softness and support. Some shredded memory foam pillows are even adjustable to make customizing easy.

Latex: Latex, made from the sap of rubber trees, is bouncy, supportive, and soft. It’s a good option for side-sleepers, but usually not adjustable like some foam pillows.


Down alternatives: Down alternative feels similar to down but is made of polyester. It’s a good alternative for those with feather allergies or people looking for a more affordable but equally soft option. However, it’s not as supportive as down can be, so it’s not the best choice for side-sleepers.

Polyester: Polyester pillows are a bit less common nowadays, but they are much cheaper than other pillow types. They do not usually keep their shape for long, so they likely won’t be supportive enough for side sleepers.

Additional Pillow Components to Consider

There are a couple of other things to think about before buying the most supportive pillow for your sleeping position, such as pillow size and cost. While these things may not be the first thing that comes to mind when pillow-shopping, be sure to at least consider them before purchasing.


Your pillow’s size can definitely influence how comfortable you are while you sleep. It’s a bit of a no-brainer, but the broader your shoulders, the bigger your pillow should be.

If you have neck pain, a cervical pillow may be best. Cervical pillows are typically smaller than standard-sized pillows and are made with ergonomic features to cradle the neck.

A standard or queen size is suitable for most sleeping positions, but again, if you have broad shoulders or just want a pillow to use as a headrest, you can consider other sizes. Euro pillows are square-shaped and typically used as throw pillows.

Pillow TypeDimensionsGood For...
Small20W" x 12L"Specific needs like neck pain or travel
Standard20W” x 26L”Most sleepers except those who toss and turn
Super Standard20W” x 28L”Those who toss and turn
Queen20W” x 30L”Those who toss and turn
King20W” x 36L”Back or headrest, broad-shouldered sleepers
EuroDimensions vary, always squareBack or headrest, throw pillows.


Cost may not be an object for you when pillow-shopping, but for others, it’s the deciding factor driving the pillow purchase.

Pillow price depends on a few different factors: the pillow type, adjustability, any additional features such as cooling technologies, as well as the return policy and warranty coverage.

Taking these things into consideration, have a look at the average cost for each pillow type as you continue your search:

MaterialAverage Cost
Down Alternative$20-30
Memory Foam$50-60

Sleep Trials, Returns, and Warranties

Sleep trials are a frequent perk with mattresses these days, but they are not as common when it comes to pillows. Depending on the brand, sleep trials for pillows last anywhere from 30-120 days.

Return policies will typically coincide with sleep trial— you can return the pillow within the sleep trial window for a full refund. However, if the company does not offer a sleep trial, you will need to do some research on their conditions for returns.

Pillow warranties can also vary, but the average length is 3-5 years, with some companies even offering lifetime warranties. Pillow warranties cover defects in the material or workmanship beyond normal use, such as seams coming apart, sagging, or changes in the shape.

Frequently Asked Questions

How thick should a side sleeper’s pillow be?

Side sleepers usually prefer mid- and high-loft pillows, around 3 to 6 inches thick, because they fill the gap between the shoulder and the head. You’ll want to consider your body type and shoulder breadth when choosing the best possible loft. Those with broader shoulders will need taller pillows, while those with smaller statures will require thinner pillows.

Are memory foam pillows comfortable for side sleepers?

Memory foam pillows are great for side sleepers because they offer cushion for the neck and head, relieving tension and preventing aches and pains in the morning. If you’re somebody who wakes up with a stiff neck or headache, a memory foam pillow may be able to ease some of that discomfort.

How many pillows should a side sleeper use?

You should always sleep with only one pillow below your head, but side sleepers can also benefit by throwing a pillow between their knees. Sleeping with a knee pillow or body pillow between your knees prevents your top leg from falling out of alignment and the lower back from twisting. Side sleeping with a body pillow is also helpful if you’re trying to transition from stomach to side sleeping.

Should you sleep without a pillow?

Side sleepers cannot get away with sleeping without a pillow because they need a cushion to fill the gap between the mattress and their head. Stomach sleepers are the only ones who can get away with sleeping without a pillow, and even most stomach sleepers choose to use a very thin pillow rather than going completely pillow-less.

What pillow firmness is best for side sleepers?

Side sleepers usually find medium pillows the most comfortable because they give the head some cushion without causing the neck to fall out of alignment. Too-firm pillows can lead to morning headaches, while too-soft pillows can lead to neck pains.

Did You Find Your Next Pillow?

When it comes to good sleep, your pillow can make all the difference. The best pillow for side sleepers has a medium loft, ample support for the neck and head, and softness. If your pillow doesn’t seem to be giving you all the support you need, it might be time to reconsider your sleep set.
