Introduction

Choosing the best pillow for side sleepers is important because your pillow plays a major role in keeping your head, neck, and spine properly aligned throughout the night. When you sleep on your side, there is a larger gap between your head and the mattress because of your shoulders. A pillow that is too flat can allow your head to tilt downward, while one that is too thick can push your neck upward. Both situations may contribute to morning stiffness and discomfort.

What Makes a Pillow Good for Side Sleepers?

Best pillow for side sleepers for a side sleeper should provide enough height, firmness, and support to keep the neck in a neutral position. Sleep experts generally recommend medium- to high-loft pillows for side sleeping, with many side sleepers finding pillows around 4 to 6 inches suitable, depending on shoulder width and mattress firmness.

A medium or medium-firm pillow is often a good starting point. It should support your head without feeling excessively hard or allowing your head to sink too deeply into the pillow.

Memory Foam Pillows

Memory foam is one of the most popular choices for side sleepers. It conforms to the shape of your head and neck while maintaining relatively consistent support. Shredded memory foam can be particularly useful because some designs allow you to remove or add filling to adjust the loft.

An adjustable memory foam pillow is a good choice if you are unsure about the ideal height. You can customize the filling until your head and neck feel properly supported.

Latex Pillows

Latex pillows are another excellent option for side sleepers. They generally provide responsive support and tend to maintain their shape instead of compressing completely under the weight of your head. Sleep Foundation's 2026 testing guide lists the Saatva Latex Pillow among its top choices for side sleepers.

Latex can also be appealing to people who prefer a slightly springier feel rather than the slower contouring sensation of memory foam.

Adjustable Pillows

If you have difficulty finding the right pillow height, an adjustable model may be the best solution. These pillows allow you to change the amount of filling, making it easier to match the pillow to your shoulder width, body shape, and mattress.

For example, Sleep Foundation currently lists adjustable models such as the Helix ComfortAdjust Cooling Pillow among its recommended side-sleeper options.

How to Choose the Right Pillow Height

Your shoulder width is an important factor when choosing pillow height. People with broader shoulders may need a higher-loft pillow, while people with narrower shoulders may be comfortable with a lower loft. Your mattress also matters because a softer mattress allows your shoulder to sink farther into the surface.

When lying on your side, your head should remain reasonably level with your spine rather than bending toward or away from the mattress.

Best Pillow Materials for Side Sleepers

The most suitable materials include memory foam, latex, and adjustable shredded foam. These materials can provide the support needed to prevent excessive sinking. Down and down-alternative pillows can also be comfortable, but very soft versions may not provide enough support for some side sleepers.

Final Thoughts

Best pillow for side sleepers is one that combines adequate loft with comfortable, consistent support. For many people, a medium-firm pillow with a medium-to-high loft is an excellent starting point. Memory foam and latex are strong choices, while adjustable pillows are ideal for sleepers who want to customize their height and firmness.

Rather than choosing a pillow simply because it is marketed for side sleepers, focus on whether it keeps your head, neck, and spine comfortably aligned. The right pillow can make your sleeping position feel more comfortable and help you wake up feeling better rested.
