Best Pillow for Side Sleepers (2026)
Why side sleepers need higher loft
Side sleepers need a higher-loft pillow than back or stomach sleepers. The pillow must fill the space between your ear and the mattress to keep your cervical spine in a neutral line with the rest of your spine. The right loft depends on your shoulder width. Broader shoulders need more height. An adjustable fill pillow is the safest choice because it lets you tune the exact loft your body needs.
#1 Best Overall: Coop Home Goods Original Adjustable
$72 queen | View on Amazon
The Coop Home Goods Original is filled with shredded memory foam that you can add or remove to adjust the loft. This adjustability is the key feature for side sleepers who often cannot know exactly what height they need until they try it. The pillow ships with extra fill so you can start high and reduce until the height matches your shoulder width.
The cover is a blend of polyester and bamboo-derived viscose that is breathable and machine washable. The entire pillow is machine washable, which is not the case for most foam pillows in this category.
Pros
- Adjustable fill lets you dial in exact loft for your shoulder width
- Machine washable — full pillow, not just the cover
- Affordable at $72 for a queen with Amazon Prime eligibility
Cons
- Takes 24-48 hours to fully expand after unboxing
- Shredded foam can feel lumpy until properly fluffed
Best for: Side sleepers who are unsure of their ideal loft height and want adjustability plus easy care.
#2 Best for Cooling: Purple Harmony Pillow
$179 standard
The Purple Harmony uses the same proprietary gel grid as Purple mattresses, but in pillow form. The grid sits over a talalay latex core that provides responsive support. The gel grid has open channels that allow heat and moisture to escape, making it significantly cooler than memory foam pillows for side sleepers who sleep warm.
The latex core is more responsive than memory foam — it bounces back faster when you change positions during the night, which reduces the sensation of being stuck in the pillow.
Pros
- Gel grid stays cooler than memory foam
- Talalay latex core is more responsive than foam — easier to change positions
- Available in two height options (standard and tall)
Cons
- Expensive at $179 for a standard size
- Not adjustable — fixed height (standard or tall versions)
Best for: Side sleepers who sleep warm and want a cooling pillow with responsive latex feel.
#3 Best Luxury: Saatva Pillow
$145 standard
The Saatva Pillow uses a microcoil support core surrounded by plush outer fill in an organic cotton cover. The microcoil center provides consistent support in the middle of the pillow where the head rests, while the surrounding fill provides the plush feel that most sleepers prefer. The zoned construction delivers targeted support where you need it.
Pros
- Microcoil center provides zoned support without the foam density
- Organic cotton cover — softer and more breathable than synthetic covers
- Plush feel that pairs well with firm mattresses
Cons
- Not adjustable
- Dry clean only — more maintenance than machine-washable options
Best for: Side sleepers who want a luxury hotel-style pillow with structured support rather than foam.

Frequently Asked Questions
What loft (height) should a pillow be for side sleepers?
Side sleepers typically need a high loft pillow of 4 to 6 inches. The goal is to fill the gap between the side of your head and the mattress, keeping your cervical spine in a neutral line with the rest of your spine. The exact height depends on your shoulder width — broader shoulders need higher loft. An adjustable pillow like the Coop Home Goods Original lets you add or remove fill to dial in the exact height your body needs.
Is memory foam or latex better for side sleeper pillows?
Both work well for side sleepers, but they have different feels. Shredded memory foam (like Coop Home Goods) is adjustable, conforms closely to the head and neck, and is machine washable. Solid memory foam holds a fixed shape, which is good for consistent support but cannot be adjusted. Latex is more responsive and bounces back faster than memory foam, which makes it easier to change positions. Talalay latex (like in the Purple Harmony) is softer and lighter than Dunlop latex.
How often should side sleepers replace their pillows?
Most pillows should be replaced every 1 to 2 years. Down pillows compress faster and may need replacing annually. Memory foam pillows last 2 to 3 years before losing their shape. Latex pillows last 3 to 4 years. Signs it is time to replace: the pillow does not spring back when folded in half, it smells, or you wake up with neck pain. Pillowcases and pillow protectors extend the useful life of any pillow.
Can the wrong pillow cause shoulder pain?
Yes. A pillow that is too low allows the head to drop toward the mattress, putting lateral stress on the neck and shoulder. A pillow that is too high pushes the head upward and inward, also straining the shoulder. Shoulder pain from a wrong pillow is most common in side sleepers because the entire weight of the head rests on the shoulder contact zone during sleep. If you consistently wake up with shoulder or neck tension, pillow height is the first variable to check.
Stop waking up with neck stiffness.
