You may not think of posture as something to consider during sleep. But as a side sleeper, it’s important to keep your head, neck, and back aligned in order to avoid pain and stiffness.

If you’re sleeping on an old or worn-out pillow, headaches, a sore neck, and shoulder or back pain may result. You may also experience numbness in your arm.

Choosing a pillow with the right amount of height and firmness can keep your neck and spine in proper alignment, leading to better sleep and pain-free mornings.

We chose these pillows specifically because of their benefits for side sleepers.

We looked at each pillow’s:

  • quality of materials and construction
  • height
  • adjustability
  • firmness
  • ease of cleaning

We also analyzed customer reviews, gauged manufacturer transparency, and considered price, keeping budget constraints in mind.

According to a 2017 study, adults tend to spend the most amount of time asleep on their sides. When done right, sleeping on your side can promote proper spinal alignment and prevent or reduce aches and pains.

Using a supportive pillow that gently cradles your neck, as well as a pillow between your knees, can help keep your spine in alignment.

Another important benefit of sleeping on your side is reduced snoring.

In order to best keep your head, neck, and back in neutral alignment, look for a medium-firm to extra-firm pillow that keeps your head around 3 to 4 inches above the mattress. Pillows that have wide side gussets are better at maintaining this height over time.

You may also want to look for a pillow that won’t go flat over time.

If you’re looking to avoid certain chemicals, like volatile organic compounds (VOCs), look for brands whose pillows use CertiPUR-US or Greenguard Gold certified materials to narrow down your options.

The ideal pillow material for side sleepers is medium-firm to extra-firm rather than soft. Down and down alternatives may be too soft for those who sleep mostly on their sides. Foam, like latex and memory foam, offers a more supportive surface for side sleepers.

Keep in mind, though, that your preference also plays a part. Despite being fans of side sleeping, some people prefer softer, down-filled pillows and sleep with two pillows instead of one.

The best size pillow for you depends mainly on your size and body type. Ideally, the pillow’s height should put your neck in a position that keeps the spine properly aligned. For most people, the ideal pillow height for side sleeping is about 4 inches or thicker.

One small 2015 study even suggests that 10 centimeters, or about 4 inches, is the most suitable pillow height overall.

  • Check the care instructions. Pillows come with care instructions from the manufacturer. You can usually find these with the pillow, online on the manufacturer’s website, or by contacting their customer service. Following these instructions can give your pillow its longest life.
  • Know the washing recommendations. Don’t machine wash a pillow that can only be spot cleaned. Doing so may result in clumping and bumps that make it impossible to sleep on. Memory foam and latex pillows often come with a do-not-wash warning.
  • Use the dryer instead. Instead of washing, some pillows can be sanitized and plumped in a dryer.
  • Use a stain remover. Using a stain remover can help you gently spot clean any pillow that can’t be washed.
  • Use a pillow cover. Using a removable, washable pillow protector will help keep your pillow cleaner for a longer period of time.
  • Replace them. When purchasing, keep in mind that even the most expensive pillow isn’t meant to last forever. To avoid sleeping on allergy triggers such as dust mites, mold, and dead skin cells, replace your pillows after around 18 months. If you use a pillow protector, this time span may be extended.

What types of pillows are best for side sleepers?

The best pillows for side sleepers are medium-firm to extra-firm pillows made of memory foam or latex foam.

How firm should your pillow be if you’re a side sleeper?

It’ll depend on your body size, but typically, medium-firm pillows work well for side sleepers. They provide the right balance of comfort and neck support.

How often should you replace your pillow?

You should replace your pillow when it no longer feels comfortable to you, or when it goes flat very easily.

Side sleepers typically benefit from sleeping on a medium-firm to extra-firm pillow that has a 3 to 4 inch loft.

A pillow made from memory foam or latex may hold its height and shape longer than one made from polyester or down.
