Does the Derila Pillow Help With Snoring? What the Research Says

TL;DR

• Derila helps mild positional snoring, roughly 40% reduction in frequency over 4 weeks
• Not a sleep apnea treatment and won’t fix severe or non-positional snoring
• Dedicated mouthpieces like the SleepZee or SnoreRx Plus are more effective for primary snoring
• The 60-day trial makes it low-risk to test, but returns require buying from the official site
• If your snoring is loud, involves gasping, or leaves you exhausted, see a sleep doctor first

The Derila Ergo pillow markets itself as a snoring aid. The butterfly contour, they claim, positions the head and neck in a way that opens the airway and cuts down on snoring. The marketing videos show before-and-after scenarios where the pillow eliminates snoring entirely.

The reality is more complicated. The Derila can help with a specific type of snoring: mild, positional snoring caused by a flat pillow letting your head tilt and restrict the airway. It cannot treat obstructive sleep apnea, and it doesn’t work for everyone who snores. Here is what the research says and what our 4-week test found.

How Pillow Position Affects Snoring

Snoring happens when the tissues in your throat vibrate as air flows past them during breathing. The vibration occurs because the airway is partially blocked or narrowed. Pillow choice affects this in two ways.

Head elevation. When your head is too flat, the lower jaw drops back and the tongue shifts toward the throat, narrowing the airway. A pillow with enough loft keeps the head elevated and the jaw forward, which maintains a wider airway opening. The sweet spot is a loft that keeps your cervical spine roughly parallel to the mattress when you’re on your back, or aligned with your spine when you’re on your side. Too low and the jaw falls back. Too high and you’re bending the neck forward, which creates its own compression.

Neck alignment. When the neck is bent (head too high or tilted to the side), the muscles and tissues around the airway are compressed. A pillow that keeps the cervical spine neutral reduces this compression. This is where contour shapes earn their keep. The Derila’s central cradle holds the head in a fixed position while the side wings provide a resting surface that keeps the neck relatively straight.

The Derila’s butterfly contour addresses both of these. The 4.7-inch loft provides head elevation, and the central cradle positions the head so the neck stays relatively neutral. For people whose snoring is caused by a flat, unsupportive pillow, this combination can reduce or eliminate snoring. If you want to try it yourself, the 60-day trial gives you a month to test whether it helps your specific snoring pattern.

But there is a critical distinction: positional snoring is not the same as obstructive sleep apnea (OSA). Positional snoring improves when you change your sleeping position. OSA is a medical condition where the airway collapses during sleep, regardless of pillow position. If you snore heavily, gasp awake during sleep, or feel exhausted despite a full night’s rest, you need a sleep study, not a pillow upgrade.

What the Research Says

The research on pillows and snoring is thin but directionally consistent. No large-scale randomized trials have tested the Derila specifically, but several studies on contour pillows and cervical alignment give us useful data.

A 2014 study in the Journal of Manipulative and Physiological Therapeutics found that contoured pillows reduce morning pain intensity compared to standard pillows, primarily through improved cervical alignment. The study did not directly measure snoring, but improved alignment is associated with reduced airway obstruction. The mechanism is clear: when the neck sits in a neutral position, the soft tissues around the airway are less likely to compress and vibrate.

A 2017 systematic review in the journal Sleep analyzed multiple studies on positional therapy for snoring, including pillow-based interventions. The review found that positional therapy can reduce mild to moderate snoring in people whose snoring is position-dependent. The key finding was that firmness and loft are the most important factors, with medium-firm pillows at appropriate height showing the best results. The review also noted that positional therapy works best for people whose snoring is significantly worse when supine (on their back) compared to lateral (on their side).

A 2017 systematic review in Sleep found that positional therapy, including pillow-based interventions, can reduce mild to moderate snoring in people whose snoring worsens on their back. The review identified firmness and loft as the two most important variables.

Research on cervical pillows and sleep apnea is limited and inconclusive. A 2020 review in Nature Communications examined whether pillow design affects airway patency and found that individual anatomy, body position, and pillow properties interact in complex ways. No single pillow design works for everyone. The study suggested that personalized fitting (adjusting loft and firmness to individual neck length and shoulder width) produces better outcomes than one-size-fits-all contour shapes.

What does this mean for the Derila? The evidence supports the general principle that contoured pillows can reduce mild, positional snoring by maintaining airway alignment. The specific claim that the Derila’s butterfly shape is superior to other contour designs lacks independent validation. It’s a pillow that follows a sound design principle, not a medical device with proven clinical efficacy.

The honest summary: contour pillows like the Derila probably help with mild, positional snoring. They are not a treatment for sleep apnea or severe snoring. The magnitude of benefit depends on whether your snoring is actually position-dependent, which is something you can test by tracking whether your snoring improves when you sleep on your side.

How We Tested

We tracked snoring over 4 weeks using the Derila pillow. Our methodology: partner-reported snoring frequency (nights per week with audible snoring) and intensity (quiet, moderate, loud) compared to a 2-week baseline with a standard flat pillow. Two testers participated: one primary snorer (back/side combination sleeper, 185 lbs) and one partner providing nightly observations. Sleep position was tracked via a motion sensor under the mattress. Room temperature was held at 68-70 degrees Fahrenheit throughout the test period.

Baseline (standard flat pillow):

• Snoring frequency: 4-5 nights per week
• Intensity: moderate to loud
• Pattern: worse when sleeping on back, better on side
• Average sleep position split: roughly 60% back, 40% side

Weeks 1-2 (Derila):

• Snoring frequency: 3-4 nights per week
• Intensity: moderate
• Pattern: still worse on back, but less loud
• Note: the adjustment period made side sleeping less comfortable initially, which may have increased back sleeping and partially offset the benefit
• Sleep position shift: back sleeping increased to roughly 70% in the first week as the tester adjusted to the contour shape

Weeks 3-4 (Derila, fully adjusted):

• Snoring frequency: 2-3 nights per week
• Intensity: quiet to moderate
• Pattern: noticeably reduced on both side and back positions
• Partner observation: snoring was quieter and less consistent, with fewer episodes of loud snoring
• Sleep position shift: settled at roughly 55% back, 45% side (closer to baseline)

Summary: Snoring frequency decreased by roughly 40% and intensity dropped from moderate-loud to quiet-moderate. This is a meaningful improvement but not a complete elimination. The Derila helped, but it didn’t stop snoring entirely. The most noticeable change was the reduction in loud episodes. The partner reported that the quieter snoring was far less disruptive than the baseline pattern, even when it didn’t disappear completely.

One thing worth noting: the first week was rough. The butterfly contour pushes your head into a specific position, and if you’re used to sprawling across a flat pillow, the adjustment feels restrictive. By week 2, the position started feeling natural. By week 3, going back to a flat pillow felt wrong.

What to Look For: Buyer’s Guide

If you’re shopping for a snoring solution, pillow or otherwise, these are the factors that actually matter.

Loft height. The pillow needs to fill the gap between your ear and the outer edge of your shoulder when you’re on your side. Too low and your head tilts, compressing the airway. Too high and you’re bending the neck forward. For most adults, that means a loft between 4 and 6 inches, but it depends on your shoulder width and body size. The Derila’s 4.7-inch loft works for average builds but may be too low for broad-shouldered people and too high for smaller frames.

Firmness. A pillow that’s too soft lets your head sink, which defeats the purpose of a contour shape. A pillow that’s too firm creates pressure points and can make neck pain worse. Medium-firm is the sweet spot for snoring reduction, and that’s what the Derila offers. If you press your hand into the pillow and your fingers sink more than an inch, it’s probably too soft for airway support.

Contour shape. The shape determines where your head sits and how your neck is supported. A butterfly contour (like the Derila) cradles the head in a central depression and uses side wings for neck support. A traditional contour pillow has two raised lobes of different heights. Both can work, but the butterfly shape tends to be more position-preserving (it keeps your head from rolling to the side), while the dual-lobe shape lets you choose your preferred height. Neither is objectively better. It depends on whether you want your pillow to enforce a position or offer options.

Material breathability. Memory foam sleeps hot. If you’re a warm sleeper, look for a pillow with ventilation holes or a gel-infused foam layer. The Derila uses standard memory foam without visible ventilation, which means it retains heat. If you already sleep hot, this could be a problem. A breathable pillowcase helps, but it’s a band-aid, not a fix.

Trial period. Contour pillows require an adjustment period of 1 to 3 weeks. A 30-day trial isn’t enough to evaluate a contour pillow properly. You need at least 60 days to get past the adjustment phase and assess whether the pillow actually helps your snoring. The Derila offers 60 days, which is adequate. Many cheaper contour pillows on Amazon offer 30 days or less, which is a red flag.

Derila vs Dedicated Snoring Solutions

The Derila is a pillow that happens to help some people snore less. It is not a snoring device. If snoring is your primary concern, dedicated solutions are more effective.

Mouthpieces: Mandibular advancement devices (MADs) like the SleepZee and SnoreRx Plus physically hold the lower jaw forward to open the airway. They are more effective than pillows for moderate to severe snoring because they address the mechanical cause directly: the jaw falling back and the tongue obstructing the throat. Our best anti-snoring mouthpieces roundup compares the top options across comfort, effectiveness, and price.

Mouth tape: Gentle adhesive tape over the lips encourages nasal breathing, which reduces snoring for some people. It works through a different mechanism than the Derila. Where the Derila repositions the head to maintain airway alignment, mouth tape prevents mouth breathing that contributes to snoring. Our mouthpiece vs mouth tape comparison covers the evidence.

Positional therapy: Devices that prevent back sleeping can reduce snoring for people whose snoring is primarily back-position-dependent. The Derila’s side wings encourage side sleeping, which contributes to its snoring benefit. Dedicated positional therapy devices (like the Rematee Bumper Belt) are more aggressive about preventing back sleeping but less comfortable.

Lifestyle changes: Weight loss, alcohol avoidance before bed, and nasal decongestants can reduce snoring intensity. These are often more effective than any pillow or device. Losing 10% of body weight has been shown to reduce snoring severity by roughly 50% in overweight individuals, according to research published in the American Journal of Respiratory and Critical Care Medicine.

How to Choose: Decision Flow

Not sure which snoring solution fits your situation? Follow the path that matches your symptoms.

• Snoring only when you sleep on your back? The Derila is a reasonable starting point. Its contour shape repositions the head to maintain airway alignment, and the 60-day trial lets you test whether positional changes reduce your snoring.
• Snoring regardless of sleep position? A dedicated mouthpiece like the SleepZee or SnoreRx Plus is more appropriate. Positional snoring solutions won’t help if your snoring persists on your side.
• Snoring with gasping or choking? See a sleep doctor first. These are signs of obstructive sleep apnea, which requires a sleep study and medical treatment. No pillow or mouthpiece replaces proper diagnosis.
• Mild snoring plus mouth breathing? Mouth tape ($8-15/month) addresses the breathing pattern directly. Some people combine mouth tape with a contour pillow for layered benefit.
• Overweight with loud snoring? Losing 10% of body weight has been shown to reduce snoring severity by roughly 50%. Lifestyle changes outperform any device.

When a Pillow Is Not Enough

See a doctor if you experience any of the following:

• Snoring accompanied by gasping or choking during sleep
• Excessive daytime sleepiness despite adequate sleep time
• Morning headaches that persist after waking
• Observed pauses in breathing during sleep
• Difficulty concentrating or memory problems

These are symptoms of obstructive sleep apnea, a medical condition that requires diagnosis and treatment. A pillow can complement medical treatment but cannot replace it. Derila makes no claim that their pillow treats sleep apnea, and they are right to avoid that claim.

If you’re not sure whether your snoring is positional or clinical, a simple test: record yourself sleeping on your back for 3 nights, then on your side for 3 nights. If the snoring drops significantly on your side, it’s probably positional. If it stays the same or only changes slightly, it’s probably not, and a pillow won’t solve it.

The Verdict

The Derila pillow can help reduce mild, positional snoring by maintaining airway alignment and encouraging side sleeping. It is not a snoring cure, and it doesn’t work for everyone. Our 4-week test showed a roughly 40% reduction in snoring frequency and a decrease from moderate-loud to quiet-moderate intensity. The risk-reward math is reasonable if your snoring is mild and position-dependent.

If snoring is your primary concern, a dedicated mouthpiece like the SleepZee or SnoreRx Plus will be more effective. If you want a pillow that supports your neck and happens to reduce snoring as a secondary benefit, the Derila does that job at an accessible price.

Frequently Asked Questions

Does the Derila pillow really stop snoring?

It reduces mild, positional snoring for many people, but it doesn’t stop snoring entirely. Our 4-week test showed about a 40% reduction in snoring frequency and a drop from moderate-loud to quiet-moderate intensity. It works best when your snoring gets worse on your back and improves on your side.

How long before I see improvement?

Most people notice a difference within the first 1 to 2 weeks, but the full benefit shows up around week 3 or 4 once you adjust to the contour shape. The adjustment period can feel awkward at first, especially if you’re used to a flat pillow.

Is the Derila better than a mouthpiece for snoring?

For moderate to severe snoring, a dedicated mouthpiece like the SleepZee or SnoreRx Plus is more effective. Mouthpieces physically hold the jaw forward to open the airway, which addresses the root cause more directly. The Derila is better suited for mild snoring where pillow position is the main trigger.

Can the Derila treat sleep apnea?

No. The Derila is not a medical device and makes no claims about treating obstructive sleep apnea (OSA). If you gasp awake during sleep, feel exhausted despite a full night’s rest, or your partner observes pauses in your breathing, you need a sleep study and medical treatment, not a pillow.

What if I’m a stomach sleeper?

Stomach sleeping generally reduces snoring because it keeps the airway more open, but it creates its own problems (neck strain, lower back pain). The Derila’s contour shape isn’t designed for stomach sleeping. If you primarily sleep on your stomach and don’t snore much, the Derila probably isn’t the right investment.

How does the Derila compare to mouth tape?

Mouth tape encourages nasal breathing, which can reduce snoring for people who breathe through their mouth at night. It’s cheaper than the Derila and works through a different mechanism. Some people combine both. Our mouthpiece vs mouth tape comparison covers the evidence in detail.

Is the 60-day trial enough time to evaluate it?

It should be. Our test showed measurable improvement by week 3 to 4, so 60 days gives you roughly double the adjustment period you need. The main risk is that you might not adjust to the contour shape at all, in which case the trial lets you return it.

What does the return process cost?

Derila offers free returns within the 60-day trial window. You ship the pillow back at no cost and receive a full refund. The catch is that you need to buy from the official site to get the trial guarantee. Third-party sellers may not honor it.

Should I see a sleep doctor before trying the Derila?

If your snoring is heavy, accompanied by gasping or choking, or leaves you exhausted during the day, yes. Those are signs of sleep apnea, which requires a sleep study and medical treatment. The Derila is for mild, positional snoring where you already know you don’t have a clinical sleep disorder.

Can I use the Derila with a CPAP machine?

The Derila’s contour shape may interfere with some CPAP mask seals, especially full-face masks. Side sleeping with a CPAP is generally fine, but the butterfly cradle might push your mask out of position. If you use CPAP, talk to your sleep doctor before switching pillows.
