We Tested 10 Pillows to Find the Best Ones for Side Sleepers in 2026

If you’re a side sleeper, you know the struggle: waking up with a sore neck, a numb arm, or that deep shoulder ache that makes you wonder if you slept on a pile of rocks instead of a pillow. It can be disappointing to wake up and not feel like your body is truly rested. Still, the truth is that side sleeping is one of the healthiest positions for your spine, but only if your pillow has your back (and neck too). A 2024 study in the Journal of Sleep Research found that side sleepers have fewer awakenings than those who sleep on their back, and using the right pillow is key to maintaining this healthy sleep pattern.

The best pillow is unique to each person. “The key, whatever your preferred sleep position, mattress, or pillow type, is to pay attention to your body, considering aches and pains as a sign of possible poor sleep ergonomics, and making the appropriate adjustments incrementally until you find your sweet spot,” explains Emeka Nwodim, MD, a board-certified orthopedic surgeon specializing in spine surgery at the Centers for Advanced Orthopaedics in Maryland.

How We Tested the Best Pillows for Side Sleepers

To find the best pillows for side sleepers, we tested 42 pillows from major bedding brands as well as emerging competitors over a two-to-three-week period. Each pillow was used nightly by a panel of testers with various preferred sleep positions, including back, stomach, side, and dynamic sleepers, as well as individuals with broad shoulders, narrow shoulders, chronic neck pain, TMJ, hip or shoulder pain, and pregnancy-related sleep changes. After their trial period, testers completed detailed surveys evaluating loft, firmness, spinal alignment, pressure relief, temperature regulation, and overall comfort.

We evaluated every pillow for how well it maintained neutral spine alignment, whether it compressed or flattened overnight, and how supportive it felt across different body types. Our criteria also included shape retention, long-term durability, cooling performance, ease of upkeep, and whether the pillow caused any stiffness or headaches upon waking. To create this list, we paid particular attention to the feedback received from self-reported side sleepers about their favorite picks.

To ensure accuracy and relevance, we consulted the latest research in sleep, biomechanics, and orthopedics, as well as experts in the field, including:

• Brandon Hirsch, MD, a board-certified orthopedic spine surgeon in California
• Emeka Nwodim, MD, a board-certified orthopedic surgeon specializing in spine surgery at the Centers for Advanced Orthopaedics in Maryland
• Lief Hands, doctor of chiropractic, a chiropractor at Precise Chiropractic & Rehabilitation in Maryland

What to Look for When Buying a Pillow

Choosing the right pillow is imperative for getting a comfortable and restorative night’s sleep. When shopping for your next pillow, it’s helpful to consider a few key factors to ensure that it matches your sleep style, comfort preferences, ideal fill, and budget. Here are some important factors to keep in mind:

• Loft and Firmness Pillow height plays a significant role in comfort for side sleepers. “The best pillow height for an individual patient is the one that keeps their neck in neutral alignment (meaning the head is in a straight line with the rest of their back, and the middle of their ears is in line with the middle of their shoulders),” Dr. Hirsch points out. “What’s most important is keeping the spine in a neutral alignment to relieve pressure on your discs and joints.”
• Material Memory foam, down, latex, and hybrid options all offer different levels of support, softness, and durability. Look for materials that hold their shape over time and can withstand regular use. If you have allergies, choose materials that resist dust mites, mold, and other common irritants.
• Breathability and Cooling Some pillows are designed to reduce heat buildup, keeping you cool throughout the night. Look for these features if you tend to sleep hot or wake up sweaty.
• Ease of Care Consider whether the pillow is machine washable or has a removable cover for easy cleaning.
• Price Balance your budget with quality. Sometimes investing a bit more upfront can mean longer-lasting comfort.

Can Pillows Help With Neck or Shoulder Pain?

The right pillow can make a huge difference in terms of neck and shoulder pain, especially if you sleep on your side. Research shows that ergonomic pillows designed to support the natural curve of your neck can reduce pain and stiffness.

In an analysis of 35 studies, people using supportive pillows reported lower neck pain scores and felt less stiffness in the morning. Another study found that adjusting pillow height helped about half of participants improve by at least three points on a standard neck-pain scale over three months.

Not all pillows are created equal: Foam, memory foam, polyester, down, and synthetic fills all feel different, and your comfort matters just as much as the science. Choosing a pillow with the right height, shape, and firmness can reduce pressure on your neck and shoulders to make your mornings feel a lot less achy. Even small changes, like switching to a pillow that supports your shoulders properly, can impact how rested you feel.

“A patient with very broad shoulders will require a taller pillow to keep their neck in neutral alignment, whereas a petite patient with narrow shoulders would require a shorter height pillow,” Hirsch explains. “My general recommendation to patients is that they sleep with both their neck and low back in a neutral position. For many patients, putting a pillow in between the knees can help maintain their pelvis and lower back in a neutral position. For the neck, it is all about finding a pillow that is the appropriate height for your shoulder width.”
