Best Pillows for Side Sleepers
Sleep Doctor’s Picks
Shredded Memory Foam
Adjustable (Soft to Medium)
$96
Adjustable (8″ Standard)
Pros
- Shredded memory foam makes the pillow adaptive to side sleepers of any body weight
- Adjustable design lets you add or remove fill to customize the loft
- Cover made from polyester and bamboo-derived viscose is breathable and moisture-wicking
Cons
- Memory foam fill can shift during the night and lose its original shape
- It can take some trial and error to find the right level of fill
For most side sleepers, the key to a comfortable pillow is ample cushioning to fill the space between the neck and downward-facing shoulder. This promotes proper alignment and reduces the potential for pressure buildup along the spine. With the Shredded Memory Foam Pillow from Sleep Is the Foundation, you can add as much fill as you need to create your ideal loft. Each order includes extra fill if you prefer maximum volume, but you can also remove the foam based on your head size and shoulder width.
Why We Like It
For our side sleepers, being able to customize how thick and firm a pillow feels is an important quality. The inner pouch makes the pillow easy to adjust without making a mess. Unlike solid foam pillows — which can be somewhat dense — this Sleep Is the Foundation model feels squishy and adaptive, forming a gentle contour around the head and neck. Temperature control is another strength. The foam retains a bit of heat, but this is offset by the breathable, moisture-wicking cover.
How Does It Feel?
The pillow’s shredded foam molds to your head and neck for a cradling effect some of our testers described as “cloud-like.” How closely the foam contours will depend on how much fill you use. Most side sleepers on our team preferred the pillow full or nearly full, while back and stomach sleepers didn’t need as much fill. Keep this in mind if you’re a combination sleeper — we recommend keeping the fill close by whenever you change positions and need to adjust the loft. The cover is composed of viscose derived from bamboo, a breathable fabric with moisture-wicking properties to keep you cool and dry. Viscose is also exceptionally soft. An inner pouch holds the foam. You can separate the outer cover from the pouch and machine-wash the former in any household machine, but the foam should never be exposed to moisture.

Why We Like It
Side sleepers on our testing team found that the Eli & Elm Cotton Side-Sleeper Pillow responded well to gentle shaping while maintaining support. Some back sleepers may also enjoy the contouring for the neck and support for the head. The shredded fill makes the pillow quite moldable, so sleepers can readjust fill to get support where they need. But it also retains its shape quite well, preventing you from having to fluff it as often. With a mix of temperature neutral latex and breathable down alternative polyester, the pillow also earned high marks from our testers who sleep hot.

Why We Like It
Our testers noted that the shredded memory foam was softer than solid memory foam but still provided a supportive feel.

Since I sleep on my side, I tend to go with a high loft pillow that’s on the firmer side so that my head doesn’t sink too far down into the pillow. I need it to keep my head propped up at just the right angle to prevent next-day soreness.
Why Pillows Are So Important for Side Sleepers
Pillows should be comfortable, but their role in supporting spinal alignment for side sleepers is just as important. If your pillow isn’t supportive enough to keep your head and neck in a neutral position, you may wake up with discomfort or neck pain.
How to Choose a Pillow for Side Sleepers
Side sleepers should choose a pillow that aligns the head and neck with the spine, providing cushioning without allowing the neck to bend unnaturally. This means finding a pillow with enough firmness and loft to lift the head away from the shoulders.
Pillow Type
We’ve found that certain types of pillows work best for side sleepers:
- Memory Foam: Pillows made from solid or shredded memory foam contour to the head and neck, generally providing excellent support and pressure relief.
- Latex: Durable and supportive, most latex pillows have plenty of firmness, are temperature neutral, and hold their shape well, offering consistent support over time.
- Polyfoam: Similar to memory foam but generally less expensive, polyfoam pillows typically offer good support. Depending on the type of foam used, these pillows may be less firm and durable than other types.
- Buckwheat: Filled with natural buckwheat hulls, these pillows are firm and breathable. The amount of fill can be adjusted, making these pillows an adaptable option for side sleepers.
Loft
The loft, or thickness, of a pillow should be at least 4 inches for most side sleepers. Those with broader shoulders may need over 6 inches for proper alignment, while people with a softer mattress may fare better with a slightly lower loft.
Firmness and Shape Retention
Firmness affects how deeply a pillow compresses under pressure, while shape retention describes how well it maintains its shape after prolonged use. Side sleepers typically benefit from medium to high firmness for adequate support, coupled with sufficient shape retention to keep the spine aligned throughout the night.
Breathability
Breathable materials like latex and buckwheat hulls allow air to flow through the pillow’s fill and prevent heat buildup. A breathable pillow can reduce overheating and sweating, making it an important feature for those who sleep warm or live in hotter climates.
Neck, Back, or Shoulder Pain
Many side sleepers experience back, shoulder, or neck pain. The right pillow can alleviate these issues by providing adequate firmness, contouring, and pressure relief for the head and neck. Side sleepers should look for pillows that provide adequate support and contouring to reduce strain on the neck and upper body.
Video: How to Pick a Pillow for Side Sleepers
Our sleep experts offer advice on how to pick a perfect pillow for side sleepers. We’ll discuss pillow designs that are best suited for this sleep position, from the type of fill to the pillow’s thickness.
How to Keep Your Spine Aligned When Sleeping On Your Side
For side sleepers, keeping the spine in a neutral position while sleeping may involve more than just the right pillow.
- Use a Pillow Between Your Knees: Placing a pillow between your knees helps maintain alignment in the hips, reducing strain on your lower back and promoting a neutral spine.
- Try a Body Pillow: A body pillow provides full-length support, aligning the hips and shoulders. It’s especially helpful for those who are pregnant or enjoy cuddling.
- Sleep on the Right Mattress: Choosing a mattress that complements your sleeping style is essential. To find the best mattress for side sleepers, look for a model that’s tailored to your body weight and comfortably contours to your shoulders and hips without letting you sink too deeply.
- Add a Mattress Topper: If a new mattress isn’t in your budget, a mattress topper can change the firmness of your sleep surface, offering additional support or cushioning based on your individual needs.

How We Test
At Sleep Doctor, our testing is grounded in extensive experience in the sleep product industry. For this guide, our team personally tested each pillow. We focused on how well each pillow supports side sleepers, assessing characteristics like firmness, loft, and overall comfort.
Frequently Asked Questions
Memory foam pillows can be an excellent choice for side sleepers due to their supportive contouring. The best memory foam pillows provide elevation and pressure relief for the head and neck, aiding in proper spinal alignment. Shredded memory foam has the added advantage of adjustability, allowing you to tailor the pillow’s loft and firmness to your specific needs.
A medium to firm pillow is typically best for side sleepers. It provides the necessary support to keep the head and neck aligned without being overly rigid. A pillow that’s too soft may cause the head to sink too much, shifting the spine out of neutral alignment and straining the neck.
For many side sleepers, a pillow height of 4 to 6 inches ensures that the head and neck are adequately supported and aligned with the rest of the spine. The ideal loft also depends on your body type and the firmness of your mattress.
The best pillow for side sleepers with neck pain should offer enough support and contouring to prevent strain and promote proper sleep posture. Pillows with memory foam fill or a contoured design may reduce neck pain by providing necessary support and promoting healthy alignment.
A pillow should primarily support your head and neck, keeping them aligned with your spine. For side sleepers, the pillow should comfortably fill the space between your head and shoulders. Your shoulders need to sink into the mattress enough to keep your spine straight, so resting them on the pillow may lift your shoulders out of alignment.
While some side sleepers like to stack pillows, we don’t recommend using two pillows under the head, as one can easily slip out during the night. It’s better to find one pillow with the appropriate loft for your body type and sleeping style. However, side sleepers can use multiple pillows to support the body. A pillow between the knees can help maintain alignment in the hips, while hugging a body pillow can provide extra comfort and stability.
