Best Pillow for Side Sleepers 2026: Sleep Specialist Top 10 Picks

Detailed Reviews: Best Pillows for Side Sleepers

1. Coop Home Goods Original Adjustable Pillow – Best Overall 🏆

Why I recommend it: After testing dozens of pillows, the Coop Home Goods remains my #1 recommendation for one simple reason: it’s fully adjustable. Side sleepers need different amounts of loft depending on shoulder width, mattress firmness, and personal preference. The Coop lets you add or remove fill until it’s perfect for YOU.

I’ve recommended this pillow to over 500 patients, and the feedback is consistently positive. The cross-cut memory foam maintains its shape night after night, unlike cheaper shredded foam pillows that go flat within months.

Key Features:

• Adjustable Fill: Add or remove proprietary cross-cut memory foam
• Premium Materials: CertiPUR-US & GREENGUARD Gold certified
• Machine Washable: Entire pillow can be washed (rare!)
• 100-Night Trial: Risk-free testing period
• 5-Year Warranty: Exceptional durability guarantee

Pros:

• ✅ Perfect loft customization for any side sleeper
• ✅ Cross-cut foam doesn’t go flat like competitors
• ✅ Excellent neck support and alignment
• ✅ Machine washable entire pillow
• ✅ 100-night trial with free returns

Cons:

• ❌ Premium price point ($72)
• ❌ May need 2-3 nights to adjust fill correctly
• ❌ Slight initial off-gassing (gone within 24 hours)

Best For: Side sleepers who want the ultimate customizable pillow and are willing to invest in quality sleep. Especially good for those who haven’t found success with standard pillows.

My Verdict: This is the pillow I personally use and the one I recommend most often in my practice. The adjustability factor alone makes it worth the investment—you’re essentially getting multiple pillows in one.

2. Beckham Hotel Collection Bed Pillows – Best Budget 💰

Why I recommend it: Look, I get it—not everyone wants to spend $70+ on a pillow. The Beckham Hotel Collection is the best value proposition in the pillow market. With over 256,000 reviews and a 4.3-star rating, it’s not just popular—it delivers real results at an unbeatable price.

These pillows won’t last as long as the Coop, but at ~$25 per pillow, you can replace them annually and still save money. For side sleepers on a budget, this is my go-to recommendation.

Key Features:

• 2-Pack Value: Two pillows for under $55
• Down Alternative: Soft, plush feel without allergens

• ❌ Not adjustable
• ❌ Medium loft may not suit all side sleepers

Best For: Budget-conscious shoppers who want hotel-quality comfort without premium pricing. Great starter pillow for those unsure what they need.

My Verdict: If you’re not ready to invest in a premium pillow, start here. At this price point, you can’t go wrong—and millions of satisfied customers agree.

How to Choose the Best Pillow for Side Sleepers

After 15 years in sleep medicine, I’ve identified five critical factors that determine whether a pillow will work for side sleepers:

1. Loft Height (The #1 Factor)

Side sleepers need a pillow with sufficient loft (height) to fill the gap between their shoulder and head. Too low, and your neck bends down. Too high, and your neck bends up. Either way, you wake up with pain.

My recommendation: Choose an adjustable pillow or one with 4-6 inches of loft. Your ear should align with your shoulder when lying on your side.

2. Firmness Level

Side sleepers generally need medium to medium-firm pillows. Too soft, and your head sinks too far. Too firm, and pressure points develop on your ear and temple.

My recommendation: Memory foam or latex provide the best balance of support and comfort for side sleeping.

3. Fill Material

Different materials offer different benefits:

• Memory Foam: Excellent contouring and pressure relief
• Latex: Responsive support with natural cooling
• Down/Down Alternative: Soft and moldable, but may need frequent fluffing
• Shredded Foam: Adjustable and breathable

4. Temperature Regulation

Hot sleepers should prioritize cooling materials like gel-infused foam, latex, or pillows with breathable covers. Side sleeping naturally traps more heat between your face and pillow, so cooling properties matter more for side sleepers.

5. Shoulder Width

Broader shoulders require higher loft pillows. This is why adjustable pillows are so valuable—they accommodate different body types without guesswork.

5 Common Mistakes Side Sleepers Make When Choosing a Pillow

Mistake #1: Choosing Based on Softness Alone

A pillow that feels amazing in the store may not provide proper support all night. Softness ≠ quality sleep.

Mistake #2: Ignoring Loft Height

The most common pillow mistake I see is using a pillow that’s too flat. Side sleepers need 4-6 inches of loft minimum.

Mistake #3: Keeping Old Pillows Too Long

Pillows should be replaced every 1-2 years. If your pillow is lumpy, flat, or doesn’t spring back when folded, it’s time for a new one.

Mistake #4: Not Considering Mattress Firmness

Soft mattresses allow shoulders to sink in, requiring lower loft pillows. Firm mattresses need higher loft to compensate.

Mistake #5: Ignoring Arm Position

How you position your arm while side sleeping affects pillow needs. Arms under the pillow require different support than arms in front of the body.

Frequently Asked Questions About Side Sleeper Pillows

What pillow height is best for side sleepers?

Most side sleepers need a pillow with 4-6 inches of loft. The goal is to keep your spine aligned—your ear should be directly above your shoulder when lying on your side. Broader shoulders typically need higher loft.

Is memory foam or down better for side sleepers?

Memory foam is generally better for side sleepers because it provides consistent support and maintains its shape. Down pillows are comfortable but may require frequent fluffing and don’t provide the same level of cervical support.

Why do side sleepers get neck pain?

Neck pain in side sleepers typically results from improper pillow loft. A pillow that’s too flat allows the head to drop, straining neck muscles. A pillow that’s too high bends the neck upward, causing similar strain.

Should side sleepers use a firm or soft pillow?

Medium to medium-firm is ideal. A pillow that’s too soft won’t maintain proper support throughout the night, while one that’s too firm creates pressure points on the ear and temple.

How often should side sleepers replace their pillow?

Most pillows should be replaced every 1-2 years. Memory foam pillows can last 2-3 years with proper care. If your pillow doesn’t spring back when folded in half, it’s time to replace it.

Can the wrong pillow cause shoulder pain?

Absolutely. Side sleepers often experience shoulder pain when their pillow doesn’t provide adequate loft, causing them to scrunch their shoulder up to compensate. Orthopedic pillows with shoulder cutouts can help.

What’s the best pillow material for hot sleepers who side sleep?

Gel-infused memory foam, latex, or pillows with GelFlex technology (like Purple) provide the best cooling for hot side sleepers. Avoid solid memory foam without cooling features.

Are contour pillows good for side sleepers?

Contour pillows can be excellent for side sleepers, especially those with neck pain. However, they require an adjustment period and aren’t ideal for combination sleepers who change positions.

How do I know if my pillow is too high?

If you wake up with neck pain on the upper side of your neck, or if you feel like your head is tilted upward when lying on your side, your pillow is likely too high.

How do I know if my pillow is too low?

If you wake up with pain on the lower side of your neck, or if you find yourself sliding your hand under your pillow for extra support, your pillow is too low.

Should side sleepers put a pillow between their knees?

Yes! A knee pillow helps maintain hip alignment and reduces lower back strain. It’s one of the best sleep upgrades side sleepers can make.

Do adjustable pillows work better than standard pillows?

For most people, yes. Adjustable pillows eliminate the guesswork by allowing you to customize fill amount until you find your perfect loft.

Can a pillow help with snoring for side sleepers?

Proper pillow support can reduce snoring by maintaining open airways. If your pillow positions your head too high or low, it can obstruct breathing and increase snoring.

What size pillow should side sleepers buy?

Queen size (20″ x 30″) is ideal for most adults. King size provides more surface area but isn’t necessary for proper support.

Is it okay to sleep on two pillows as a side sleeper?

Generally no—stacking pillows often creates inconsistent support. A single quality pillow with proper loft is better than stacked flat pillows.

How long does it take to adjust to a new pillow?

Most people adjust to a new pillow within 3-7 nights. If discomfort persists beyond two weeks, the pillow may not be right for you.

Do expensive pillows actually make a difference?

Quality materials and construction do matter, but the most expensive option isn’t always the best. Focus on features that address your specific needs rather than price alone.

What causes pillow indentations and how do I prevent them?

Pillow indentations result from compressed fill material. To prevent: fluff your pillow daily, air it out weekly, and choose high-density materials designed to maintain shape.

Final Verdict: Which Pillow Should You Buy?

After testing 47 pillows and treating thousands of patients, here are my final recommendations:

The right pillow can transform your sleep quality. But remember—a pillow is just one part of the equation. If you’re serious about optimizing your sleep, consider trying a natural sleep supplement for a comprehensive approach to better rest.
