The Complete KumoFlex Loft Guide: How Much Filling Should You Really Use?

Buying an adjustable pillow is only the first step toward sleeping better.

The real difference comes from knowing how to adjust it properly.

Many people unzip their pillow, see a bag of memory foam cubes, and immediately wonder:

"How much foam should I remove?"

"How high should my pillow actually be?"

"Am I using too much?"

"Why does it still feel uncomfortable?"

If you've ever asked these questions, you're not alone.

The truth is that there isn't one perfect pillow height for everyone. Your body, sleeping position, shoulder width, mattress firmness, and even how often you change positions during the night all affect the amount of support you need.

That's exactly why we created the KumoFlex Adjustable Cooling Memory Foam Pillow.

Instead of forcing you to adapt to a fixed-height pillow, KumoFlex lets you customise your pillow until it fits your body—not someone else's.

Why Fixed Pillows Don't Work for Everyone

Walk into any store and you'll probably see pillows labelled:

• Low
• Medium
• High

But here's the problem.

Two people who are both 170cm tall can need completely different pillow heights.

One may have broad shoulders.

Another may sleep mostly on their back.

Someone else may toss and turn throughout the night.

Yet many pillows expect everyone to sleep comfortably on exactly the same height.

That's why people often spend hundreds of dollars buying pillow after pillow, hoping the next one will finally feel right.

Usually, it doesn't.

The Biggest Mistake People Make

Many people believe:

"A thicker pillow must provide better support."

Actually, the opposite can happen.

When a pillow is too high:

• Your neck bends upwards.

• Your muscles remain under tension all night.

• Your shoulders cannot relax.

• You may wake with headaches or neck stiffness.

On the other hand...

When the pillow is too low:

• Your head drops backwards.

• Your neck loses proper support.

• Your shoulders sink unevenly.

• Pressure builds across your upper back.

The goal isn't the highest pillow.

The goal is the right pillow height for your body.

The Golden Rule

A properly adjusted pillow should allow your:

✓ Head

✓ Neck

✓ Spine

to stay in one comfortable, neutral line.

When this happens:

• Your neck muscles can finally relax.
• Pressure around your shoulders is reduced.
• You move less throughout the night.
• Sleep feels deeper and more restorative.

That is what you're adjusting KumoFlex to achieve—not simply making it softer or firmer.

How Much Filling Should Side Sleepers Use?

Side sleepers usually need the most support.

Why?

Because your shoulder creates a gap between your head and the mattress.

If your pillow is too low, your head tilts downward.

KumoFlex recommendation:

✔ Start with Medium–High Loft

✔ Keep most of the AoYuki Flex Cube Memory Foam inside.

✔ Remove only a small amount if it feels too tall.

A properly adjusted pillow should keep your nose aligned with the centre of your chest rather than pointing up or down.

---

How Much Filling Should Back Sleepers Use?

Back sleepers generally need balanced support.

Too much foam pushes the head forward.

Too little lets the head fall backwards.

KumoFlex recommendation:

✔ Start with a Medium Loft

✔ Remove a small handful if your chin points towards your chest.

✔ Add foam if you feel your neck isn't fully supported.

The ideal feeling is gentle support beneath the natural curve of your neck while allowing your head to rest comfortably.

---

How Much Filling Should Stomach Sleepers Use?

Stomach sleepers usually need the lowest loft.

A thick pillow forces the neck into an awkward angle for hours.

KumoFlex recommendation:

✔ Remove more foam than most users.

✔ Aim for a Low Loft.

✔ Keep only enough foam for light cushioning.

Because KumoFlex is adjustable, stomach sleepers don't have to search for a special low-profile pillow—they can simply customise one pillow to suit their needs.

---

What About Combination Sleepers?

If you move around throughout the night, you're actually one of the biggest reasons adjustable pillows exist.

Rather than trying to optimise for just one sleeping position, aim for a balanced setup.

Our recommendation:

✔ Start with a Medium Loft.

✔ Sleep with it for 2–3 nights.

✔ Make only one small adjustment at a time.

Small refinements often produce the biggest improvements.

Don't Try to Perfect It on Night One

One of the biggest mistakes people make is adjusting the pillow every single morning.

Your body needs time to adapt.

Instead:

Night 1–3:
Leave it alone.

Night 4:
If it still feels slightly high, remove a little foam.

Night 7:
Adjust again if necessary.

Think of it like adjusting the seat in a new car—you don't usually find the perfect position within five minutes.

Why KumoFlex Makes Adjustment So Easy

Unlike solid memory foam pillows that cannot be changed, KumoFlex uses 100% AoYuki Flex Cube Gel-Infused Memory Foam, allowing you to fine-tune the loft by adding or removing foam cubes.

That means:

✓ One pillow for different body types

✓ One pillow for different sleeping positions

✓ One pillow that adapts as your comfort needs change

It also includes a separate rope bag for storing extra foam, so your unused filling stays clean and ready whenever you want to make adjustments.

• 100% AoYuki Flex Cube Gel-Infused Memory Foam

Why KumoFlex Is Worth the Price

Some people compare pillows only by price.

We believe it's better to compare by value over time.

Many standard pillows are fixed-height.

If they don't suit your body, your only option is to buy another one.

With KumoFlex, you're investing in a pillow that can be adjusted as your needs change.

Whether you change mattresses, alter your sleeping position, or simply want a different feel, your pillow can adapt with you.

You're also getting premium materials, dual comfort surfaces, breathable construction, certified foam, and personalised support in a single product.

That's why many customers see KumoFlex as a long-term sleep investment rather than just another pillow purchase.

Final Thoughts

The perfect pillow isn't the tallest.

It isn't the softest.

And it certainly isn't the one someone else recommends.

The perfect pillow is the one that fits your body.

That's the philosophy behind KumoFlex.

Instead of forcing your neck to adapt to a fixed design, KumoFlex gives you the freedom to adjust your loft, personalise your support, and enjoy a pillow that evolves with your sleep.

Because better sleep doesn't start with a one-size-fits-all pillow.

It starts with one that finally fits you.
