Fill & Construction
The Alkyonos uses shredded memory foam fill rather than a solid block, which allows the foam pieces to shift and conform to your head and neck curves throughout the night. The zippered bamboo cover gives you direct access to the fill so you can add or remove foam to adjust the loft , a feature found in less than a third of pillows on the market.
Extra stuffing is included, so you can start full and dial back to your preferred thickness.
Firmness & Support
Out of the package, this pillow lands at a soft-to-medium firmness that customers consistently describe as a comfortable medium feel. The adjustable fill means you can firm it up by keeping all the foam in, or soften it further by removing some.
The shredded foam design provides cervical support and promotes proper neck alignment across all three sleep positions , side, back, and stomach , making it genuinely versatile rather than a compromise.
Cooling & Breathability
The bamboo viscose cover is naturally breathable and moisture-wicking, paired with airflow channels designed to move heat away from your head. About 57% of pillows now include some cooling feature, and this one takes a dual approach with both cover material and ventilation.
That said, customer feedback is split , some report staying cool all night while others notice warmth, so expectations should be tempered if you run especially hot during deep sleep.
Care & Durability
The bamboo viscose cover is removable via zipper and machine washable, making regular cleaning straightforward. The shredded memory foam fill itself should be spot-cleaned only , do not put it in the washer.
OEKO-TEX certification confirms the materials have been tested for harmful substances, and the hypoallergenic construction resists dust mites and common allergens. At 4.31 lbs per pillow, the dense fill should maintain its supportive loft longer than lighter fiber-fill alternatives.
Who Is This Pillow For?
Ideal For
- ✓ Side sleepers who need cervical support , the adjustable loft lets you build up enough height to keep your neck in proper alignment with your spine
- ✓ People with neck pain seeking customizable comfort , remove or add fill until you find the sweet spot that relieves pressure on your cervical area
- ✓ Couples wanting a matching pillow set , the 2-pack means consistent comfort on both sides of the bed without buying separately
- ✓ Hot sleepers who want breathability , bamboo viscose cover and airflow channels help regulate temperature better than standard polyester covers
Not Ideal For
- ✕ Sleepers who prefer a completely uniform, solid foam feel , shredded fill has a different texture than a single molded memory foam pillow
- ✕ Anyone highly sensitive to new-product odors , some buyers report off-gassing that may take a few days to fully clear
- ✕ Buyers who want a fully machine-washable pillow , only the cover goes in the washer, not the foam fill
These pillows ship compressed and vacuum-sealed. After unboxing, give them 24-48 hours to fully expand and for any initial foam odor to dissipate before use.
Toss the pillows in the dryer on low heat for 10-15 minutes after unboxing to speed up fluffing and reduce any initial smell
Start with all the fill inside and sleep on it for a night or two before removing foam , it's easier to take fill out than to re-stuff evenly
Warranty details should be verified directly with Alkyonos, as specific coverage terms are not listed in the product data. The OEKO-TEX certification does confirm independent safety testing of the materials used.
FAQ
How do I adjust the loft on these Alkyonos pillows?
Unzip the bamboo viscose cover and remove handfuls of shredded memory foam until the pillow reaches your preferred height and firmness. Extra stuffing is included so you can also add fill back.
Side sleepers typically need more loft for proper neck alignment, while stomach sleepers benefit from removing more fill to keep the head lower.
Are these pillows good for neck pain and cervical support?
Yes , the adjustable shredded memory foam lets you customize the loft to match your body's curves and maintain proper neck alignment. The foam conforms around your head and neck rather than pushing back like a solid pillow.
Multiple customers report improved posture while sleeping and reduced pain.
Can I wash the entire pillow or just the cover?
Only the bamboo viscose cover is machine washable , remove it via the zipper and wash on a gentle cycle. The shredded memory foam fill should be spot-cleaned only.
Do not submerge the foam in water or put it in a washing machine, as it won't dry properly and can develop mold.
Do these pillows sleep hot or stay cool?
The bamboo viscose cover is naturally breathable and the pillow includes airflow channels to help with temperature regulation. Customer feedback is mixed , some sleepers find them cool all night, while others who run especially hot notice some warmth.
They perform better than solid memory foam pillows for comfort and breathability, but may not match dedicated gel-infused cooling pillows.
Is there an off-gassing smell when you first open them?
Some customers report no smell at all, while others notice a noticeable foam odor right out of the package. This is common with memory foam products and typically dissipates within 24-72 hours.
Airing them out in a well-ventilated room or tumbling in the dryer on low heat speeds up the process.
What size pillowcase fits these queen pillows?
These measure 28x19 inches, which is standard queen pillow sizing. Any standard queen pillowcase (typically 20x30 inches) will fit comfortably.
The pillow may feel slightly fuller than traditional fill pillows at 4.31 lbs each, so avoid very tight-fitting pillowcase styles.

Bottom Line
The Alkyonos shredded memory foam 2-pack delivers genuine adjustability and solid comfort as an entry-level option. The combination of customizable loft, bamboo cover breathability, and cervical support makes it a strong all-position pillow for sleepers who want to fine-tune their setup.
If you're sensitive to foam odors or need a pillow you can throw entirely in the wash, look at fiber-fill alternatives instead.
Best for sleepers who want one pillow they can customize for any position , side, back, or stomach , with proper neck alignment support
Consider alternatives if you need a fully machine-washable pillow or are highly sensitive to memory foam off-gassing
