Why Your Pillow Matters for Side Sleeping
Waking up with a stiff neck or aching shoulder is no way to start the day, especially for the 60% of us who sleep on our sides. The right pillow can transform your sleep by aligning your spine and easing pressure points. As a lifelong side sleeper who’s tested countless pillows to tame my own neck pain, I’ve learned that finding the perfect one is a game-changer.
The Side Sleeper’s Struggle
Side sleeping promotes spinal alignment and reduces snoring, but it demands a pillow with enough loft and firmness to fill the gap between your shoulder and head. I once woke up with a crick in my neck after using a flimsy pillow—never again. The best pillows for side sleepers in 2025 offer tailored support and comfort.
What Makes a Great Side Sleeper Pillow?
A pillow for side sleepers needs specific qualities to ensure proper alignment and comfort. It should have a loft of 4–6 inches, medium-firm to firm support, and breathable materials to keep you cool. Let’s dive into what sets these pillows apart.
Key Features to Look For
The ideal pillow balances loft, firmness, and breathability. After testing pillows for months, I found that adjustable fills and ergonomic shapes make a huge difference. These features cater to individual body types and preferences, ensuring a pain-free morning.
Loft and Height
A pillow’s loft should fill the space between your shoulder and neck, keeping your spine neutral. Experts like Terry Cralle, a clinical sleep educator, recommend 4–6 inches for most side sleepers. My broad-shouldered friend swears by a 6-inch loft for perfect alignment.
Firmness and Support
Medium-firm to firm pillows prevent your head from sinking too low, which can strain your neck. I once tried a soft down pillow that felt luxurious but left me aching. Firmer options like memory foam or latex are often better for side sleepers.
Material Matters
Common materials include memory foam, latex, down alternative, and hybrid fills. Shredded memory foam molds to your head, while latex offers springy support. I’ve found that cooling gel-infused foams are a lifesaver for hot sleepers like me.
Shape and Design
Contoured or crescent-shaped pillows cradle the neck and shoulders. The Pillow Cube’s rectangular design blew me away during testing—it filled the shoulder gap perfectly. Ergonomic shapes are a trend to watch in 2025.
Top 10 Pillows for Side Sleepers in 2025
After extensive research and personal testing, here’s my curated list of the best pillows for side sleepers in 2025. Each was evaluated for comfort, support, durability, and cooling properties based on lab tests and real-world feedback.
1. Eli & Elm Organic-Cotton Side-Sleeper Pillow
This pillow’s crescent shape and adjustable shredded memory foam fill make it a standout. It offers medium-firm support and a cooling cotton-polyester cover. Testers loved its balance of plush comfort and neck alignment.
Why It’s Great
The unique shape reduces shoulder pressure, and the adjustable loft suits various body types. I adjusted mine to a 5-inch loft, and it’s been a dream for my neck pain. It’s pricey but worth it for dedicated side sleepers.
2. Nest Bedding Easy Breather Side-Sleeper Pillow
With a curved edge and adjustable shredded foam, this pillow provides firm support without the chemical smell common in foam pillows. It’s fully washable and comes in a side-sleeper-specific version.
Customizable Comfort
I removed a quarter of the fill for a perfect fit, and it stayed cool all night. Its 30-day return policy and two-year warranty add peace of mind. This pillow is a favorite for its moldability and durability.
3. Saatva Latex Pillow
This pillow features a shredded Talalay latex core and a plush microdenier outer layer, offering a 6–7-inch loft. Its organic cotton cover and cooling properties make it ideal for hot sleepers.
Plush Yet Supportive
A tester called it “like sleeping on a cloud with a spine.” I appreciated its non-adjustable but perfectly balanced loft for my taller frame. It’s not cheap, but its durability justifies the cost.
4. Coop Cool+ Adjustable Pillow
The Coop Cool+ comes in a cutout shape, perfect for side sleepers with shorter frames. Its gel-infused memory foam and cooling cover keep heat at bay, even in warm climates.
A Cool Companion
I’ve used this pillow through two humid summers, and it never felt sweaty. The adjustable fill lets you fine-tune the loft, though the synthetic cover needs a pillowcase for comfort.
5. Sleep Number ComfortFit Pillow Ultimate
This pillow’s three removable layers of shredded foam and down alternative allow for ultimate customization. It’s lofty and breathable, ideal for side and combination sleepers.
Tailored to You
I kept all three layers for side sleeping, and it supported my neck perfectly. Its 100-day return policy is a bonus, though it’s pricier than some competitors.
6. Layla Kapok Pillow
Combining shredded memory foam and kapok fibers, this pillow offers a moldable, cuddly feel. Its adjustable loft and breathable cover make it versatile for side sleepers.
Soft Yet Supportive
I removed half the fill for a mid-range loft, and it felt like a hug. Hot sleepers will appreciate its airflow, but frequent fluffing is needed to maintain shape.
7. Pillow Cube Side Cube
This rectangular pillow’s 5-inch height and firm memory foam fill the shoulder gap perfectly. Its Ice Cube version adds a cooling cover for hot sleepers.
A Game-Changer
The unique shape took a night to get used to, but it eliminated my shoulder pain. It’s best for strict side sleepers, as it’s less versatile for other positions.
8. Tuft & Needle Original Foam Pillow
Made with adaptive foam infused with cooling gel, this medium-firm pillow contours without feeling heavy. It’s a solid choice for side sleepers with neck pain.
Cool and Contouring
I didn’t notice much cooling, but the support was spot-on for my neck. Hand-washing is a downside, but its three-year warranty adds value.
9. Beckham Hotel Collection Down Alternative Pillow
This budget-friendly pillow offers a plush, down-like feel with hypoallergenic polyester gel fiber. It’s less supportive but durable for the price.
Affordable Comfort
I’ve used these for years, and they hold up well. They’re softer than ideal for side sleepers, but great for those who hug their pillows.
10. Dr. Mary Side Sleeper Pillow
This boomerang-shaped pillow from Pillow Bar lets you hug one arm while resting your head on the other. It’s designed for side sleepers who love cuddling.
Hug-Worthy Design
I loved hugging this pillow, but flipping it when switching sides was a hassle. It’s perfect for dedicated side sleepers but not combination sleepers.
Comparison: Memory Foam vs. Latex vs. Down Alternative
| Feature | Memory Foam | Latex | Down Alternative |
|---|---|---|---|
| Support | Contours closely, medium-firm | Springy, firm | Plush, less supportive |
| Cooling | Can trap heat unless gel-infused | Naturally breathable | Breathable, less contouring |
| Durability | High, holds shape well | Very high, long-lasting | Moderate, may flatten |
| Price Range | $50–$150 | $80–$200 | $20–$80 |
| Best For | Neck pain relief | Eco-conscious sleepers | Budget-conscious sleepers |
Memory foam excels for contouring, latex for durability, and down alternative for affordability.

How to Choose the Right Pillow
Selecting a pillow involves matching loft, firmness, and material to your body and sleep style. Consider your shoulder width, mattress firmness, and whether you run hot. Testing pillows with generous return policies, like Sleep Number’s 100-day trial, is key.
Tips for Testing Pillows
Sleep on a new pillow for at least a week to adjust. I learned this after dismissing a pillow too quickly—by night three, it was perfect. Check return policies and warranties to ensure flexibility.
Body Type Considerations
Broader shoulders need higher lofts (5–6 inches), while petite frames may prefer 4–5 inches. My shorter friend loves the Coop Cool+ cutout shape for her small stature.
Cooling Needs
Hot sleepers should prioritize gel-infused foam or latex. The Saatva Latex Pillow kept me cool during a heatwave, unlike some memory foam options.
Budget vs. Quality
While budget picks like Beckham are tempting, investing in a $100+ pillow like Eli & Elm often pays off in durability and comfort. I regretted cheaping out on a $20 pillow that flattened in months.
