Fill & Construction
The Alkyonos uses shredded memory foam fill rather than a solid block, which is what makes the loft adjustable , you unzip the cover and physically add or remove handfuls of foam. At 4.53 lbs per pillow, there's a generous amount of fill included, and customers note the foam doesn't get hard or lumpy when cold, a common complaint with entry-level shredded foam pillows.
Firmness & Support
Rated soft with adjustable firmness, this pillow starts on the plush side but can be firmed up by keeping all the fill in or softened further by removing some. It's designed for all three sleeping positions , side, back, and stomach , with neck alignment as a priority.
Stomach sleepers benefit most since they can reduce the loft to nearly flat, while side sleepers should keep more fill for proper cervical support.
Cooling & Breathability
The bamboo viscose cover is the primary cooling feature here, offering natural breathability and moisture-wicking that synthetic covers can't match. The shredded foam fill also helps , air circulates between the foam pieces far better than it would through a solid memory foam block.
Customers specifically call out the cooling effect as a noticeable improvement over their previous pillows.
Care & Durability
The bamboo cover is removable via zipper and machine washable, making regular cleaning straightforward. The shredded foam fill itself is spot-clean only, which is standard for this pillow type.
OEKO-TEX certification confirms the materials have been tested for harmful substances, and the shredded foam construction tends to maintain its shape longer than fiber fill since you can refluff and redistribute the pieces over time.
Who Is This Pillow For?
Ideal For
- ✓ Stomach sleepers who need a low-loft pillow , remove fill to create a thin profile that prevents neck strain in face-down positions
- ✓ Hot sleepers frustrated with traditional memory foam , the bamboo viscose cover and shredded fill allow significantly more airflow than solid foam
- ✓ Allergy sufferers who want certified safety , OEKO-TEX testing and hypoallergenic materials mean fewer reactions and no harmful chemicals
- ✓ Couples buying together , the 2-pack with queen sizing fits standard bed setups and saves versus purchasing individually
Not Ideal For
- ✕ Sleepers who prefer a solid, structured memory foam feel , shredded fill shifts and conforms differently than a contoured one-piece pillow
- ✕ Anyone who wants a fully machine-washable pillow , only the cover goes in the wash, not the foam fill itself
- ✕ Heavy side sleepers (200+ lbs) who need maximum loft and firm support , the soft rating may compress too much under heavier loads
These pillows ship compressed and vacuum-sealed. After unboxing, remove from the packaging, give them a good shake and fluff, and allow 24-48 hours for the shredded memory foam to fully expand and any manufacturing odor to dissipate.
Toss the pillows in the dryer on low heat for 10-15 minutes to speed up expansion and eliminate any initial foam smell
Before first use, unzip the cover and adjust the fill amount , start with all the foam in, then remove handfuls until the loft matches your sleeping position
Warranty details should be verified directly with Alkyonos, as coverage terms can vary by seller and marketplace listing. Retain your original packaging and order confirmation in case a claim is needed.
FAQ
How do I adjust the loft on these Alkyonos pillows?
Unzip the bamboo cover to access the shredded memory foam fill inside. Remove handfuls of foam to lower the loft for stomach sleeping, or keep all the fill in for maximum height suited to side sleeping.
Store any removed foam in a storage bag so you can re-add it later if your preference changes.
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.
This is standard for memory foam pillows and helps preserve the foam's structure and longevity.
Are these pillows good for side sleepers with neck pain?
Yes, they work well for side sleepers with neck pain because you can adjust the fill amount to find the exact loft that keeps your spine aligned. Side sleepers generally need more fill than back or stomach sleepers to bridge the gap between shoulder and head.
The shredded memory foam conforms to your neck's contour, providing targeted support where you need it.
Do these pillows sleep hot like regular memory foam?
They sleep noticeably cooler than solid memory foam pillows. The shredded fill allows air to circulate between the foam pieces, and the bamboo viscose cover naturally wicks moisture and regulates temperature.
Customers specifically praise the cooling effect, making these a strong pick for hot sleepers.
Will a standard queen pillowcase fit these pillows?
Yes, at 28x19 inches these are standard queen dimensions. Any queen-size pillowcase will fit properly.
The pillow's thickness will depend on how much shredded foam you keep inside, but the footprint matches standard queen sizing.
What does OEKO-TEX certified mean for this pillow?
OEKO-TEX certification means the materials have been independently tested and verified free from harmful substances like formaldehyde, heavy metals, and certain dyes. Combined with the hypoallergenic construction, this makes the pillow a safer choice for allergy sufferers, children, and anyone sensitive to chemical off-gassing in bedding.

Bottom Line
The Alkyonos shredded memory foam pillow set delivers where it counts: genuine adjustability, effective cooling, and certified-safe materials at a 2-pack tier. It's a smart buy for households with mixed sleeping positions since each person can customize their own loft.
Just know that the soft baseline firmness won't suit everyone , if you need firm, structured support, a solid memory foam or latex pillow will serve you better.
Best for multi-position sleepers and hot sleepers who want one adjustable pillow that adapts to any sleeping position
Consider alternatives if you need firm, high-loft support or want a pillow that's fully machine washable including the fill
