Is KumoFlex Right for You?

Made for anyone who’s tired of waking up sweaty, stiff, or still exhausted.

Neck & Shoulder Pain

You wake with tight shoulders or a stiff neck and need better alignment.

Hot Sleepers

You flip your pillow to the “cold side” all night or wake up sweaty.

All Sleep Positions

You sleep on your side, back or stomach and hate “one-height fits all” pillows.

Kids to Seniors

You want one skin-safe pillow that works for kids, teens, adults and seniors.

 What You’ll Notice After Switching to KumoFlex

Not just specs — this is how your nights finally feel restful again.

Less Morning Stiffness

Customisable loft supports your neck’s natural curve, so you wake up less tight and sore.

Cooler, Drier Sleep

Breathable cover and cooling foam help you wake up fresh instead of sweaty and sticky.

Deeper, Calmer Rest

Foam cubes cradle your head, reduce tossing, and help you stay asleep longer.

Inside the KumoFlex Adjustable Pillow

AoYuki Flex Cube Technology for Adaptive, Breathable Support

Each KumoFlex Adjustable Pillow is filled with 100% pure AoYuki Flex Cube Memory Foam — tiny precision-cut cubes that move with you while keeping their shape. A breathable mesh gusset lets hot air escape, while the dual-sided cover gives you a cooling side for humid nights and a cozy side for rainy days. The result: a pillow that stays supportive, bouncy, and cool, even after long nights and many washes.

Customisable loft for every sleep position

Find Your Perfect Pillow Height

Customisable loft for every sleeping style.

Side Sleepers:
Keep most of the cubes in to fill the gap between your shoulder and head.

Back Sleepers:
Remove about ¼ of the cubes for a medium loft that follows your neck’s natural curve.

Stomach Sleepers:
Remove around ⅓ of the cubes for a lower loft that keeps your neck neutral.

Every KumoFlex comes with a rope bag to store extra foam, so you can tweak the loft as your body or habits change.


Tip: Adjust your loft after 2–3 nights — your body needs time to adapt.

Many pillows mix cheaper fillers into their foam. KumoFlex doesn’t.

Not All “Shredded Foam” Is the Same

Most pillows hide mixed fillers inside — KumoFlex keeps it pure.

✅ 100% pure memory foam cubes — no polyester or scrap fillers, so support stays consistent.

✅ High-density cubes that bounce back instead of flattening or sagging.

✅ Low-odor, low-VOC foam, CertiPUR-US® certified for safer sleep.

ABOUT THE PILLOW

What makes KumoFlex different from regular pillows?

KumoFlex is fully adjustable — you can add or remove AoYuki Flex memory foam cubes to customise height and firmness. Regular pillows are fixed, flatten faster, and can’t be tailored to your body.

What filling does it use?

It uses 100% pure AoYuki Flex Cube Cooling Memory Foam, not mixed polyester or scrap foam. This gives better support, shape retention, and airflow.

Is it suitable for all ages (kids, seniors, pregnancy)?

Yes, for ages 4+ with supervision. It’s supportive enough for adults and seniors, and adjustable enough to be made softer or lower for kids and pregnant users.

Does it flatten over time?

The foam may soften slightly with use (normal for memory foam), but it’s designed not to collapse like cotton or polyester. If it feels lower, you can simply add more cubes.

Is it noisy when shifting?

No. The cubes move quietly inside the inner cover. There are no crunchy or plastic sounds like some cheap fillings.

What size is it?

It’s designed as a standard ergonomic/contour-style pillow size suitable for most Singapore beds and pillowcases (you can adjust loft inside without changing external size).

SLEEP POSITION & COMFORT

Is it suitable for side, back, and stomach sleepers?

Yes. Just adjust the amount of foam: -Side sleepers: more loft (higher fill) -Back sleepers: medium loft -Stomach sleepers: lower loft / softer

Does it help with neck, shoulder, or back pain?

It’s designed to support your neck and align your spine better than flat pillows. Many users feel less stiffness, but results may vary by individual.

Will it reduce morning stiffness?

Good alignment + proper height can reduce strain on the neck and shoulders, which often translates to less morning stiffness over time.

Does it help align my spine?

Yes. When adjusted correctly for your height and sleep position, it helps keep your head, neck, and spine in a neutral line.

Will it help with snoring?

It may help if your snoring is related to poor neck alignment. A better-supported head and neck can help keep your airway more open.

Can it relieve migraine or tension headache?

It doesn’t treat medical conditions, but better neck support can help reduce tension-based headaches in some users.

COOLING & BREATHABILITY

Does it trap heat?

No. AoYuki cubes are cooling gel–infused and cut into cubes to create airflow channels, reducing heat build-up compared to solid memory foam.

Does it stay cool all night?

It’s designed to stay cooler and less stuffy than normal pillows. In a very hot room, it will still warm slightly but won’t trap heat as much.

Will it feel too cold in AC rooms?

Most users feel it as comfortably cool, not icy. In strong AC, you can use a slightly thicker pillowcase if you are very cold-sensitive.

Is it suitable for hot sleepers?

Yes — it’s specifically made for hot, humid climates and people who wake up sweaty with normal pillows.

ADJUSTABILITY & LOFT

Can I adjust firmness and height?

Yes. Add more cubes for higher & firmer, remove cubes for lower & softer.

How do I adjust loft properly?

Unzip, remove or add cubes, zip back, then press and fluff the pillow to distribute the cubes evenly before lying down and testing.

Will the cubes clump together?

No, the cube shape helps them settle evenly and resist clumping compared to shredded scraps.

Can I add and remove foam anytime?

Yes. You can tweak it as often as you like until you find your ideal feel.

Does it come with extra foam?

Yes, it typically comes with a generous filling; in most cases you’ll be removing some foam rather than needing more.

How often should I adjust the loft?

Only when your body or sleeping style changes — e.g. new mattress, pregnancy, recovery, or if you just want a different feel.

Can I use AoYuki Flex cubes from other pillows?

Yes, as long as they’re genuine AoYuki cubes. Just be sure not to overfill.

MATERIALS & SAFETY

Is it hypoallergenic?

Yes. Materials are hypoallergenic, low-VOC, and safe for most sensitive users.

Is it OEKO-TEX® certified?

The textile components are made using OEKO-TEX®-certified materials, safe for direct skin contact.

Is it CertiPUR-US® certified?

The foam is made using CertiPUR-US® standards — low VOC, no harmful chemicals or heavy metals.

Is it safe for babies, kids, seniors?

For babies/infants, we don’t recommend any high loft pillow. For kids 4+, teens, adults, seniors, it’s safe when used appropriately.

CARE & WASHING

Can I wash the pillow?

You can wash the outer cover only. The foam cubes must not be machine washed or soaked.

Can I wash the inner foam?

No. Spot clean only. Water soaking the foam can damage its structure.

How to remove new-foam smell?

Air the pillow in a cool, shaded area for a few hours. The mild “new foam” scent will fade.

How often to fluff or air the pillow?

Every 2–4 weeks, give it a shake and fluff, and air by a window (in shade).

Best way to deep clean it?

Wash the cover, spot-clean small marks on the inner lining, and air the foam (no direct sun, no soaking).

DURABILITY & LONGEVITY

How long will the pillow last?

With normal use and care, it’s designed to last 3–5 years without collapsing like regular pillows.

Does the cover pill or fade?

It’s made to be anti-pilling and color-stable, but harsh detergents or rough washing may shorten its life.

Will the foam deteriorate?

All foam ages over many years, but high-density AoYuki cubes are engineered to resist crumbling and sagging.

Will it lose cooling performance over time?

The cooling effect comes from the foam structure and materials, not coatings, so it will not “wash off”. It may feel slightly less cool if the cover is very old or thick.

USAGE & COMPATIBILITY

Can I use it with adjustable beds?

Yes, it adapts easily to different bed inclines and positions.

Is it good for people who toss and turn?

Yes. The cube structure moves with you while still staying supportive.

Is it suitable for pregnant users?

Yes — many pregnant users like a slightly higher side-sleep loft to relieve pressure.

Can elderly parents use it safely?

Yes. It’s light, supportive, and easy to adjust to a softer, lower height.

Can it be used as a knee or leg support pillow?

Yes. You can place it under the knees or between the legs for alignment and pressure relief.

DELIVERY, RETURNS & POLICY

How fast is local delivery?

Usually 1–3 business days after order processing, excluding weekends and public holidays.

What is the return or exchange policy?

Does it come vacuum-packed?

Yes, it may be compressed for shipping. This doesn’t affect performance.

How long to fully expand after opening?

Let it rest for about 30–60 minutes, then fluff and adjust cubes as needed.

POPULAR QUESTIONS

Why is this pillow worth the upgrade?

You’re not just buying a pillow — you’re buying adjustable, cooling support that you can fine-tune for your body, instead of guessing and replacing pillows over and over.

Does it come with free extra cubes?

It comes with ample filling. For most users, there is more than enough foam, often too much at first.

It’s made from hypoallergenic, certified-safe materials, so it’s suitable for most allergy-prone users.

Can I buy foam refills?

Yes — our AoYuki Flex Cube Memory Foam refill packs are available separately.

It can be both, depending on how you set it up. You are in full control — soft, medium, or firm.
