If you’ve ever spent the night flipping and fluffing the pillow in sleepy frustration, then you know the importance of a good one can’t be overstated—and your choice can drastically determine the quality of your sleep. That being said, you’re going to want to find a pillow that suits your unique sleep style and position (and they have different meanings, BTW). Do you sleep on your back and wake up feeling sore and achy the next morning? Need pillows for back pain? What about TMJ pain? Are you switching positions all night long? And did you know that a designated side sleeper pillow can address the needs of side and combination sleepers?

Personally, I’m a side sleeper all the way—and according to sleep studies, most Americans are too. Because side sleeping is easily one of the most popular sleep positions, and when done properly, it’s considered one of the best sleeping positions for certain aches and pains. There are plenty of pillow options to pick from that can help you maintain proper alignment (a blessing and a curse if you’re easily overwhelmed by choice like me). To make finding the best pillow for side sleepers easy, we asked sleep experts for guidance.

What kind of pillow should a side sleeper use?

Sleep experts agree that the best pillows for side sleepers are the ones that sufficiently fill that gap between your shoulder and the side of your head, and support neck and spinal alignment—otherwise you could risk neck and upper back pain come morning.

“Side sleepers should choose pillows that are firm enough to align their head and neck with their spine, yet cushioned enough to alleviate pressure points on their shoulders and necks,” says Susan Miller, a certified sleep technician RPSGT, at SleepMattressHQ.com. Miller goes on to say that latex or memory foam pillows are often the types that can hit that sweet spot of cushioned and supportive. “Foam or latex pillows typically offer the best support that side sleepers need while sleeping,” agrees Logan Foley, a sleep science coach and product expert at SleepFoundation.org.

While you may be tempted to stack pillows in search of more support (I myself am guilty of this), the experts agree that sleeping with more than one pillow isn’t a good idea. “Using two pillows is not recommended for side sleepers because it can cause the head to be positioned too high, which can cause neck and shoulder pain,” explains Miller. “Instead, use one pillow that provides the necessary support and sufficient cushioning.” If you really want to use two pillows, try putting the second pillow between your knees. “While it’s not necessary by any means, some side sleepers prefer to use two pillows—one for their head and one to place between their knees to maintain a neutral spine alignment,” says Bridget Chapman, a sleep expert and certified sleep science coach at Sleepopolis.

How many inches should a pillow be for a side sleeper?

When it comes to side sleeper pillows, the length of a pillow doesn’t really matter. However, the height is ultra-important. “A pillow for side sleepers should be higher or thicker than one for back or stomach sleepers because side sleepers require a proper amount of support to keep their head, neck, and spine aligned,” explains Drew Miller, VP of Marketing at Sit ‘n Sleep. With this in mind, Dr. Danielle Wall, a sleep advisor for Sit ‘n Sleep recommends choosing a pillow that is somewhere between four and six inches tall. “The four to 6-inch loft allows side sleepers to maintain proper spinal alignment and prevent strain on the neck and shoulders,” she explains. Because of the way the body is shaped when sleeping on your side, Dr. Wall adds that it is crucial that a pillow adequately fills the space between the head and mattress in order to keep the neck in a more neutral position. 

What should side sleepers look for when pillow shopping?

Loft

According to the experts, the single most important thing to look for when choosing a pillow for side sleepers is the loft, or height, of your pillow. Remember the gap between your shoulder and side of your head I mentioned earlier? A pillow with sufficient loft should fill that space comfortably. “Side sleepers should generally seek a pillow with a higher loft (4″ or more) to help them maintain a neutral spine alignment,” says Chapman. “Pillows with adjustable loft are something that side sleepers should keep an eye out for since they allow you to fine-tune the height of your pillow to optimize comfort and support,” explains Ryan Fiorenzi, a certified sleep coach and founder of StartSleeping.org.

Material & fill

When it comes to material, sleep experts have several recommendations. “A good pillow material to look for when shopping for a side sleeper is shredded foam,” says Elisa Regulski, a certified sleep science coach and editor at Mattress Clarity. “Shredded foam will be plush enough to offer neck support, but is also responsive and will allow you to sink into it just enough to keep proper spinal alignment.” Latex and memory foam pillows were also repeat recommendations from sleep experts, because they offer support while still cradling your neck and shoulders to keep you comfy and properly aligned. “Many side sleepers prefer memory foam in both their pillow and their mattress to give them the contouring and pressure relief they need at the neck, shoulders, and hips,” Chapman adds.

Shape

Experts say the shape of your pillow is key to keeping your neck and head supported, and preventing pain that may come as a result of side sleeping. “If you’ve ever experienced neck pain and find the base of your neck unsupported as a side sleeper, you may want to look out for a cervical or contoured pillow,” advises Fiorenzi. That said, it’s important to remember that the best pillow shape for you will depend on your body type (read: the space between your shoulders and head), and your own personal preference.

Firmness

To keep the void between your shoulder and head filled, you’ll want to choose a pillow with adequate firmness and support that’ll keep its shape all night long. While the degree of firmness is largely up to personal preference, experts recommend staying within the firm category for optimal support. “Side sleepers should look for a pillow that provides support without being too firm,” says Miller. “Side sleepers are generally going to be most comfortable on a medium-firm pillow.”

Frequently asked questions

Do side sleepers need a soft or firm pillow?

Experts recommend a firmer pillow for side sleepers, but you can find soft pillows that still have a generous loft. As long as the pillow is thick enough to support your head and neck in a side sleeping position (think four to six inches), it doesn’t need to be hard as a rock.

Do side sleepers need two pillows?

Our experts actually don’t recommend using two pillows, as too much height can throw your neck out of alignment. However, you can always place a second pillow between your knees while you sleep on your side.

Are there special pillows for side sleepers?

All of the pillows on our list are recommended for side sleepers because of their cushion and medium loft. However, the right pillow for you will depend on your body size in relation to the pillow. Adjustable pillows (like the Layla Kapok Pillow or Coop Home Goods Pillow) are great for side sleepers because you can remove or add the fill until the height is just right for you.
