The Very Best Pillows for Side Sleepers

If you like snoozing on your side, you’re in good company — it’s the sleep position preferred by 60 percent of adults. But side-sleeping is more than a comfortable way to cozy up; according to Keith Cushner, a product expert at, and his colleague Logan Foley, a sleep-science coach and the managing editor at, it’s also good for your health. Side-sleeping is “one of the healthiest sleeping positions because of its ability to improve spinal alignment, reduce the risk of snoring, and reduce back pain,” Cushner tells us. But to achieve the perfect spine, neck, and head alignment, choosing the right pillow is key. Dr. Rennes Toussaint-Keshinro, a chiropractor and mental-health coach, tells us that a side sleeper should “maintain a neutral position/posture of the back,” which means your pillow should lift your head high enough that it lines up with your neck and your spine but not so high that it puts painful stress on that area.

While firmness and fill type are dictated by your sleeping preference, Cushner and Foley say that the loft, or height, of your pillow, is more important if you sleep on your side. “Side sleepers usually need thicker pillows to fill the space between their head and neck, but a pillow that is too thick may cause neck pain and put pressure on the spine,” Foley said. We spoke to Cushner, Foley, Toussaint-Keshinro, and three more experts about what to look for in pillows for side sleepers and which ones they recommend.

What we’re looking for:

Loft: The loft, or height, of your pillow is a crucial factor for side sleepers to consider. Dr. Toussaint-Keshinro explains that “keeping your head, neck, and shoulders in a neutral and even position is most important. If a pillow is too flat or too high, it can create an uneven muscle tone in the neck and shoulders, leading to spasms over time.” While there isn’t a formula to figure out the ideal loft of your pillow, Dr. Dennis Colonello, celebrity and professional-athlete chiropractor at Peak Wellness and all33 co-founder, suggests that your pillow be around four inches off of your mattress. But don’t go breaking out your ruler just yet, as there is wiggle room with this number. For taller people with broader shoulders, a higher loft may be more comfortable, and conversely, a petite person with more narrow shoulders will likely rest comfortably with a lower loft.

Firmness: All of our experts agreed that medium-firm pillows tend to be the best option for people sleeping on their side. While there is room for personal preference here, a medium-firm pillow helps your head stay in the right position without sinking while you sleep. For people who like to dream on a bed that feels like fresh brioche buns instead of a firmer surface, gusseted-down and down-alternative pillows can be a plush compromise. Additionally, Cushner and Foley suggest memory foam pillows, as they sort of mimic the softness of down by contouring to your body, while still providing support.

Shape: Specialty pillows for side sleepers come in various shapes to help position your shoulders, neck, and head while you sleep. Whether these pillow shapes actually make a difference in your sleep quality is up for debate, and Dr. Thomas Schuler, chairman of the National Spine Health Foundation’s Medical and Scientific Board and founder of the Virginia Spine Institute, explains that “these pillows are a relatively new product without much academic research examining their effectiveness.” However, he allows that “if a person tries one and finds that it seems to give some pain relief, then that’s excellent.” For people navigating chronic pain, a specialty pillow with a unique shape may be worth a shot, as they are designed to relieve bodily stress. Meanwhile, for the average side sleeper who is simply looking for comfort and support, a standard pillow shape can likely get the job done.

Eli & Elm Organic-Cotton Side-Sleeper Pillow

Eli & Elm Organic-Cotton Side-Sleeper Pillow$130

 now 20% off

From $104

75 percent latex, 25 percent polyester fiber fill | Adjustable loft | Adjustable firmness | Machine-washable cover

With a unique “U” shaped design, Eli & Elm’s side-sleeping pillow nestles into the space between your head, neck, and shoulders like a puzzle piece to create the ideal spine alignment. It’s filled with a blend of soft and supportive noodled latex and polyester fiber, and you can adjust the height and firmness by removing or adding filling. According to Cushner, most side sleepers need medium-to-high-loft pillows that provide “enough cushioning for the head and neck without sinking too low,” so the customizable fill level will help you figure out the loft that works best for your body. The filling is encased in a liner that is protected by a machine-washable exterior cover, however, the brand also sells a special pillowcase that fits the shape of the pillow seamlessly (and which you can bundle with the pillow at the time of purchase).

Himoon Sleeping Pillows

Himoon Sleeping Pillows


Microfiber fill | High loft | Medium-soft | Machine-washable

Covered in silky-smooth microfiber material, this set of two pillows is filled with CertiPUR-US & GREENGUARD Gold downlike fiber. The fluffy fiber fill, combined with the bowed pillow shape, creates a plump and springy surface to support your head and neck.

Best memory-foam pillow for side sleepers

Nectar Sleep Resident Pillow

Nectar Sleep Resident Pillow


Shredded memory foam | Adjustable loft | Adjustable firmness | Spot-clean

Memory-foam pillows are a dream for side sleepers, according to Cushner and Foley, owing to their thick filling and ability to contour to a person’s body. The Nectar Sleep Resident pillow has a pillow-in-pillows construction that provides the contoured support of traditional memory foam surrounded by a cushy outer layer to add plushness. The pillow will arrive intentionally overstuffed so that you can remove fill as necessary to adjust it to fit your sleeping needs. Dr. Janet Kennedy, clinical psychologist and founder of NYC Sleep Doctor, advises that memory foam can trap heat, making temperature regulation more challenging. However, thanks to the shredded-foam filling, the pillow is still breathable and doesn’t trap heat.


Best height-specific pillow for side sleepers

Pillow Cube Classic

Pillow Cube Classic


Memory foam | High loft | Firm | Machine-washable cover

We get it, this pillow looks like a brick — but there is actually some logic behind the Pillow Cube. The pillow is designed to completely fill that essential space between your head and the mattress to keep your neck aligned. Similar to the Elm & Eli pillow above, the Pillow Cube settles into that gap like a missing puzzle piece to lift your head into the perfect alignment.

Instead of the U-shaped cutout that snuggles closer to your shoulders, the Pillow Cube has a 90-degree angle to hold your head in place. It’s also on the firmer side and made of solid viscoelastic polyurethane and nanofibers (read: sturdy memory foam). The breathable, machine-washable cover helps to keep things cool while you snooze, and you can choose from two sizes that coincide with your height — the standard size is meant for people who are six-foot-three or shorter, the “thick” size for people who are six-foot-four or taller. And if you run especially hot, you can upgrade to an “ice cube” cooling cover for an extra $30.

Yes, water beds went out of style a few decades ago but Alanna McGinn, the founder and CEO of Good Night Sleep Site, and Dr. Toussaint-Keshinro both agree that water pillows are the gold standard for people in need of more neck support. Water pillows are “perfect for any type of sleep position and many are chiropractor-approved, as the firmness provides the support for head, neck, and spine alignment that will help individuals with chronic pain,” explains McGinn. A favorite of Dr. Toussaint-Keshinro, the Water Pillow by Mediflow has a soft layer of fiber that sits atop a layer of water that you fill yourself to create a responsive pillow that can help reduce neck pain. The uniquely adjustable pillow can be made firmer by adding more water or softer by removing some.

Best body pillow for side sleepers

Snuggle-Pedic Bamboo Shredded Memory Foam Body Pillow

Snuggle-Pedic Bamboo Shredded Memory Foam Body Pillow


Memory foam | Medium loft | Medium-firm | Entire pillow is machine-washable

Body pillows are not exclusive to pregnancy and can offer total support for those who need it. Dr. Schuler tells us that aiming for proper alignment during sleep should apply to your whole body, advising side sleepers to always “focus on having proper support under their head and between their knees.” Having these two supports in place “will keep the spine in a neutral position, reduce malalignment, and relieve pressure placed on the neck and back,” he says, pointing to research that shows a pillow between your knees when lying on your side “can reduce pressure on the spine by nearly half.” Filled with shredded memory foam and covered in breathable bamboo fabric, the Snuggle-Pedic full-body pillow supports your knees, legs, and back while you sleep by helping to evenly distribute your weight. Since it is filled with memory foam, the pillow is able to hug and conform to your body for the ultimate level of support. And perhaps best of all, the entire pillow is machine-washable.
