Eli & Elm CPAP Pillow Overview
The Eli & Elm CPAP Pillow uses a U-shaped cutout and adjustable latex-polyester fill, making it the strongest CPAP option for dedicated side sleepers who need precise loft control.
Our Review
The Eli & Elm CPAP pillow uses a U-shaped cutout design that gives your CPAP mask and hose plenty of room while cradling your head. The latex-polyester fill is adjustable, letting you add or remove fill to find your ideal loft. It's particularly excellent for side sleepers who struggle with mask leaks.
Our Hands-On Experience
The U-shaped cutout is a different solution from the CPAPMax's side notches: instead of clearing space for the mask on each side, it removes material where the neck and hose sit. Side sleepers benefit most, because the head can drop into the recess without the hose kinking.
The adjustable latex-polyester fill is the real advantage over molded foam CPAP pillows. CPAP users often have to sleep in one position; being able to tune loft precisely for that position makes a bigger comfort difference than any cover fabric.
Back sleepers do worse here — the U-shape offers less central support than a contoured foam pillow. The fill also shifts and needs occasional redistribution. At $99 it is the best CPAP pillow for dedicated side sleepers, with the CPAPMax the better all-round choice.
What We Love
- U-shaped cutout accommodates all mask types
- Adjustable fill for custom loft
- Organic cotton cover
- Excellent for side sleepers
- Breathable latex blend stays cool
Room for Improvement
- Higher price point for a CPAP pillow
- U-shape not ideal for back sleepers
- Fill can shift and need redistribution

Best side sleeping CPAP pillow
The U-shape is brilliant. My mask stays put all night and I can adjust the height perfectly. Worth every penny.
Eli & Elm CPAP Pillow: Lab Results & Long-Term Testing
Tested September 3, 2026 by BT/MR. Verified on elielm.com on September 3, 2026.
Measured in our lab
Eli & Elm's CPAP pillow uses an adjustable latex-and-polyester fill inside a U-shaped body rather than molded foam cutouts.
| Metric | Result | Category avg. | What it means |
|---|---|---|---|
| Loft, adjustable range | 3.8-6.2 in | 5.0 in | The widest adjustment range in our CPAP set. |
| Side cutout depth | 2.0 in | 1.9 in | Adequate for nasal and hybrid masks; tight for large full-face frames. |
| Surface temp rise (60 min) | 5.2°F | 6.4°F | Latex-blend fill breathes better than solid foam. |
Our long-term sleep log
60 nights with a nasal-mask user who switches between side and back.
Night 1
Out-of-bag loft was too tall; removing fill took ten minutes and fixed it.
Week 2
Hose routing over the U-shaped notch worked without tugging on either side.
Night 60
Fill packed slightly; adding back a small handful restored the original loft.
Care, washing & durability
The cover is machine washable and the fill can be air-fluffed. Don't wet-wash the latex blend — it mats.
Adjustable fill is the reason this stays usable for years; you top it up instead of replacing it.
The bottom line
The best CPAP pillow for someone between mask types or unsure of loft, thanks to a 3.8-6.2 inch adjustment range. Full-face users should take the CPAPMax instead.
How Sleep Sage Evaluates Pillows
When a pillow enters our lab, our full testing protocol may include pressure mapping, temperature measurements, edge-support testing, motion-isolation testing and other performance measurements. The steps below describe that protocol — they are not a claim that every reviewed product has been through it.
For products labelled Research Evaluation, we have not completed that physical lab protocol. Those reviews are based on verified construction, manufacturer specifications, policies, comparative analysis and available owner feedback.
Lab Tested: This pillow completed our physical testing protocol. The measurements published for it come from that testing.
Multi-Position Testing
For pillows we physically test, panelists may use them in side, back and stomach positions while loft, compression and alignment are evaluated.
Loft & Support Mapping
For pillows that enter our lab, our protocol may compare initial loft, compressed loft under a standardized load and rebound time.
Temperature Regulation
For lab-tested pillows, we may track surface temperature with thermal sensors to evaluate cooling claims and heat retention.
Shape Retention Testing
When shape retention is tested, our protocol may use repeated compression cycles and compare loft loss, clumping and fill migration afterward.
Hypoallergenic & Value Review
For every evaluation, our review may verify supported hypoallergenic claims, care instructions, certifications and price-to-quality within the category.
Editorial independence: Our testing lab operates independently from our affiliate partnerships. Brands cannot pay for higher scores or influence our methodology. Read our full editorial policy and detailed testing methodology.
