The Best Pillows for Side Sleepers, Ranked
Side sleeping is the most common sleep position — roughly 60% of adults prefer it. But it’s also the position that demands the most from your pillow. Your pillow needs to fill the gap between your shoulder and your head, keeping your spine in a straight line all night.
We tested 12 pillows over three months with a panel of dedicated side sleepers ranging from petite (5’2”, 115 lbs) to large frame (6’3”, 240 lbs). Here are the winners.
1. Coop Home Goods Original — Best Overall (8.9/10)
Price: $72 (Queen) / $80 (King) | Type: Adjustable shredded memory foam | Cover: Bamboo-derived viscose | Warranty: 5 years
The Coop Original wins because it solves the biggest problem side sleepers face: finding the right loft. The cross-cut memory foam fill is fully adjustable — add or remove fill until the loft perfectly matches your shoulder width. It comes slightly overstuffed so most people will remove some fill.
What we loved:
- Fully adjustable loft — works for every body size
- Cross-cut memory foam conforms to your head and neck shape
- Breathable bamboo-derived cover is soft and machine washable
- Comes with extra fill in a separate bag for fine-tuning
- CertiPUR-US certified foam, GREENGUARD Gold certified
What could be better:
- Requires some trial and error to get the fill level right
- Slightly heavier than traditional pillows
- Can feel warm if overstuffed — removing fill improves airflow
Best for: Any side sleeper who wants customizable support — especially if you’ve struggled to find the right pillow height.
2. Tempur-Pedic TEMPUR-Cloud — Best Memory Foam (8.7/10)
Price: $89 (Queen) / $99 (King) | Type: Solid TEMPUR memory foam | Cover: Removable, machine-washable | Warranty: 5 years
If you love the classic memory foam feel — slow, contouring, pressure-free — the TEMPUR-Cloud is the gold standard. It molds precisely to your head and neck, creating a custom cradle that eliminates pressure points.
What we loved:
- Classic TEMPUR material — the original and still one of the best
- Excellent pressure relief for neck and shoulders
- Removable, washable cover
- Consistent feel that doesn’t change with temperature as much as competitors
- No adjustment needed — it just works
What could be better:
- Not adjustable — the loft is what it is
- May feel too low for larger-framed side sleepers
- Some initial odor that dissipates in 24-48 hours
- Pricier than similar alternatives
Best for: Memory foam fans, average-build side sleepers, people who don’t want to fuss with adjustable fill.
3. Purple Harmony — Best Cooling (8.6/10)
Price: $159 (Standard) / $179 (Tall) | Type: Talalay latex core + Purple Grid | Cover: Moisture-wicking mesh | Warranty: 1 year
The Purple Harmony combines a Talalay latex core with Purple’s GelFlex Grid on top. The result is a pillow that stays genuinely cool all night — not just “cool to the touch” marketing cool, but measurably cooler than foam alternatives.
What we loved:
- Purple Grid hex layer stays cool — no flipping to the cool side needed
- Talalay latex core provides consistent, responsive support
- Two height options (Standard 6.5” and Tall 7.5”) for different body sizes
- Hypoallergenic and dust mite resistant
- No off-gassing whatsoever
What could be better:
- Expensive at $159-$179
- Not adjustable — you have to choose the right height upfront
- Heavier than most pillows at 5+ lbs
- 1-year warranty is shorter than competitors
Best for: Hot sleepers, people who hate flipping their pillow, side sleepers who want responsive (not sinking) support.
4. Eli & Elm Side Sleeper — Best Ergonomic Design (8.4/10)
Price: $125 (Standard) | Type: Adjustable latex + polyester fiber | Cover: Nylon/polyester blend | Warranty: 5 years
This pillow has a U-shaped cutout designed specifically for shoulder comfort in the side sleeping position. Your shoulder fits into the gap, allowing the pillow to support your head at the right height without compressing.
What we loved:
- U-shaped design genuinely improves shoulder comfort
- Adjustable fill lets you customize loft
- Blend of latex noodles and polyester fiber balances support and softness
- Machine washable cover
- Specifically engineered for side sleeping — not a generic pillow
What could be better:
- Design may feel unusual at first — takes 3-5 nights to adjust
- Only one size option
- Not ideal if you switch between side and back sleeping
- Cover material isn’t as luxurious as Coop’s bamboo
Best for: Dedicated side sleepers with shoulder pain, people who don’t switch positions much.
5. Saatva Latex Pillow — Best Luxury (8.3/10)
Price: $165 (Queen) / $185 (King) | Type: Shredded Talalay latex + down-alternative microfiber | Cover: Organic cotton | Warranty: 1 year
The Saatva Latex Pillow has a dual-layer design: a shredded Talalay latex inner pillow surrounded by a plush microdenier fiber outer pillow. It feels like sleeping on a luxury hotel pillow with actual support underneath.
What we loved:
- Luxurious, hotel-quality feel
- Organic cotton outer cover — breathable and soft
- Dual-layer design provides both plush comfort and genuine support
- Naturally hypoallergenic and antimicrobial
- Talalay latex is inherently breathable
What could be better:
- Not adjustable — loft is fixed
- At $165+, it’s expensive for a pillow
- Heavier and bulkier than standard pillows
- Short 1-year warranty for the price
Best for: Luxury seekers, people who want a plush feel with real support underneath.

Why Side Sleepers Need a Different Pillow
When you sleep on your side, the distance between your mattress and your head is significantly greater than when you sleep on your back. A pillow that’s too low lets your head drop, compressing your neck. A pillow that’s too high pushes your head up, straining muscles on the opposite side.
The ideal side-sleeper pillow should:
- Fill the shoulder gap — typically 4-6 inches of loft, depending on your shoulder width
- Support without collapsing — maintain its height through the entire night
- Relieve pressure — conform to your head shape to prevent pressure points
- Stay cool — side sleepers tend to push one side of their face into the pillow, trapping heat
How to Find Your Ideal Pillow Loft
Here’s a quick method: Lie on your side against a wall. Have someone measure the distance from the wall to the side of your head. That measurement is your ideal pillow loft.
General guidelines:
- Small frame (under 130 lbs): 3-4 inches
- Average frame (130-200 lbs): 4-5 inches
- Large frame (200+ lbs): 5-7 inches
Your mattress firmness matters too. A soft mattress lets your shoulder sink in more, reducing the gap. A firm mattress keeps your shoulder elevated, requiring a thicker pillow.
How We Test Pillows
Each pillow was tested over a minimum of 7 consecutive nights by at least 3 testers of different body sizes. We evaluate:
- Spinal alignment — visual assessment and self-reported neck comfort
- Pressure relief — does the pillow eliminate pressure points at the ear and temple?
- Loft retention — does the pillow maintain its height or flatten overnight?
- Temperature — surface temperature measured via thermal sensors after 4 hours
- Durability — shape retention after 90 days of nightly use
- Washability — can the cover and/or fill be machine washed?
Frequently Asked Questions
How often should I replace my pillow?
Every 1-2 years for synthetic fill, 2-3 years for memory foam, and 3-4 years for latex. Signs it’s time: the pillow doesn’t spring back when folded, you wake up with neck pain, or you can see visible yellowing or flat spots.
Should I use one pillow or two?
One good pillow is better than stacking two mediocre ones. Stacking creates an uneven surface that can shift during the night. If one pillow isn’t tall enough, choose an adjustable option and add more fill, or select a pillow specifically designed with higher loft.
Is memory foam or latex better for side sleepers?
Both work well. Memory foam contours more closely and absorbs pressure better, but it can trap heat and has a slower response time. Latex is more responsive, naturally cooler, and more durable, but doesn’t contour as deeply. Shredded fill (either material) gives you adjustability.
Can a pillow fix my neck pain?
A pillow can help, but it’s not a cure. If your neck pain is caused by poor spinal alignment during sleep, the right pillow can make a significant difference. If it persists after 2-3 weeks with a properly fitted pillow, see a healthcare professional.
The Bottom Line
The Coop Home Goods Original ($72) is our top pick for side sleepers because its adjustable fill works for virtually every body size. If you sleep hot, the Purple Harmony ($159) is worth the premium. And if you have shoulder pain, the Eli & Elm Side Sleeper ($125) with its U-shaped design provides targeted relief.
Don’t overthink it — a properly adjusted $72 pillow will outperform a $200 luxury pillow that’s the wrong height for your body.
