Are You Experiencing Any of These?
Made for people who are tired of waking up stiff, sweaty, or still exhausted.
Neck or Shoulder Stiffness
Your pillow doesn’t match your height or posture — causing tightness.
Hot or Sweaty Sleep
You flip to the “cold side” — and still wake up warm.
One-Height Pillows Don’t Work
You change positions, but your pillow can’t adapt.
Skin Safety Matters (Kids Included)
You want materials that are gentle, clean, and certified safe.
What Changes When You Start Sleeping Better
Because good sleep shows up in more ways than one.
Less Morning Stiffness
Adjustable loft supports your natural neck curve.
Cooler, Drier Sleep
Gel-infused foam + breathable mesh = no more humidity wake-ups.
Deeper Rest, Less Tossing
Cubes cradle your head evenly for calmer nights.
Skin-Friendly Comfort
Safe materials reduce friction — even better with Aoteni Tencel covers.
Complete Your Sleep System
Designed to pair perfectly with KumoFlex.
Upgrade your KumoFlex with a pillowcase designed to enhance everything the pillow is built for — cooling, comfort, and skin-friendly sleep.

AoYuki Flex Cube Technology
Why cube foam works better than solid foam:
- Moves individually to match your neck and shoulder shape
- Creates more airflow channels to stay cool
- Prevents heat pockets (a common issue with solid memory foam)
- Bounces back instead of flattening
- Lets you customise your loft without lumps or clumps
Quick benefits:
✔ Adaptive support ✔ Better airflow ✔ No clumping ✔ Heat escapes faster
A good pillow isn't one height — it's the height that fits your body.
Find Your Perfect Pillow Height
- Side Sleepers: Medium–High Loft
- Back Sleepers: Medium Loft
- Stomach Sleepers: Low Loft
- Mixed Sleepers: Adjustable Loft
Tip: Adjust gradually over 2–3 nights to let your body adapt.
Many pillows mix cheaper fillers into their foam. KumoFlex doesn’t.
Not All “Shredded Foam” Is the Same
KumoFlex only uses 100% AoYuki Flex Cube Memory Foam:
✔ Uniform density
✔ Even bounce
✔ Long-lasting loft
✔ CertiPUR-US® certified
✔ Low-VOC, safer for kids & sensitive users
Bonus: Pair it with Aoteni Tencel Cooling Pillowcases to reduce friction, minimize irritation, and increase breathability.

PRODUCT BASICS
What is KumoFlex?
KumoFlex is an adjustable memory foam pillow that allows you to customise the height, firmness, and contour using removable AoYuki cooling foam cubes. It adapts to any sleeping position and body type.
What makes it adjustable?
Instead of a fixed-height pillow, KumoFlex contains hundreds of cube-shaped memory foam pieces. You can add or remove cubes to create your ideal loft and support.
Who is this pillow suitable for?
Everyone — side sleepers, back sleepers, stomach sleepers, mixed sleepers, hot sleepers, sensitive skin users, kids, adults, and seniors.
Is it good for hot sleepers?
Yes. Gel-infused cubes, breathable mesh, and a cooling outer fabric help release heat and prevent sweaty wake-ups.
Is it suitable for children?
Yes — just remove more cubes to lower the loft for growing necks.
USAGE & SLEEPING POSITION
How do I adjust the pillow height correctly?
Lie down and adjust cubes until your neck stays aligned with your spine — not tilted up or down.
How much foam should side sleepers remove/add?
Side sleepers typically need medium–high loft to fill the shoulder gap and align the spine.
How should back sleepers adjust it?
Use a medium loft to support the natural curve of the neck.
What is the ideal loft for stomach sleepers?
Use low loft. Remove more cubes to avoid neck twisting.
I toss and turn — how should I set my pillow?
Adjust it to medium height for balanced support in all positions.
SAFETY & MATERIALS
Is the foam CertiPUR-US® certified?
Yes — free from toxic chemicals, heavy metals, and ozone depleters.
Are the covers OEKO-TEX® certified?
Yes — safe for prolonged direct skin contact.
Is the pillow hypoallergenic?
Yes — dust-mite resistant and safe for sensitive or allergy-prone users.
Is it safe for acne-prone or eczema-prone skin?
Yes. The smooth fabric reduces irritation.
For even gentler comfort, pair with Aoteni Tencel pillowcases.
Does it contain latex?
No — 100% latex-free.
COMFORT & PERFORMANCE
Will it flatten over time?
No — the cubes retain shape and support for years.
Does the cooling effect last?
Yes — gel infusion and mesh ventilation work continuously through the night.
Does the bamboo side feel warm?
It feels cozy but breathable. For maximum cooling, use the performance-fabric side.
Will the cubes clump together?
No — their shape prevents clumping.
CARE & WASHING
Can I wash the pillow cover?
Yes — machine wash on gentle cycle.
Can I put the cover in a dryer?
Yes — tumble dry low.
Can I wash the foam?
No — never soak the foam. Only spot clean if needed.
How do I clean spills?
Spot clean gently and let the foam air dry completely.
How should I store extra cubes?
Use the included rope bag and keep in a dry, cool place.
Will washing shrink the cover?
Minimal shrinkage if washed gently.
