KumoFlex Adjustable Cooling Memory Foam Pillow (Custom Height Neck Support)
Adaptive Sleep Comfort · Adjustable Cooling Pillow · Everyday Rest
A thoughtfully engineered pillow made with AoYuki Flex Cube Memory Foam, certified safe and designed to support neck alignment, cooling comfort, and personalised sleep — night after night.
Each element is designed to work cleanly and gently, allowing airflow through the adjustable cube structure while maintaining balanced support. The result is a sleep experience that feels cooler, lighter, and more naturally aligned — never stuffy, never restrictive.
Adjustable Cooling Memory Foam Pillow | AoYuki Flex Cube Technology | CertiPUR-US® • OEKO-TEX® • GRS Certified | Neck, Spine & All-Sleep-Position Support
The pillow that adapts to you — not the other way around.
Designed for Singapore’s warm, humid nights, KumoFlex combines adjustable support with cooling memory foam to help reduce neck pain, overheating, and restless sleep.
Most pillows are made at a fixed height — which means they’re either too high, too flat, or too warm.
KumoFlex Adjustable Pillow is designed to solve that. Using AoYuki™ Flex Cube Cooling Memory Foam, it lets you fine-tune the height and firmness to suit your sleep position, neck shape, and comfort preference — while staying cool all night.
✓ Adjustable Height Support
Customise the loft for side, back, or stomach sleeping — no more neck strain.
✓ Cooling Structure That Releases Heat
Gel-infused foam + breathable mesh helps prevent night sweats.
✓ Certified-Safe Materials
Skin-safe, low-VOC foam suitable for adults, kids, and sensitive sleepers.
✨ Sleep Even Cooler
Pair KumoFlex with Aoteni Tencel Pillowcases for a silkier, cooler sleep surface — ideal for hot sleepers.
Is this what your nights feel like?
Made for people who are tired of waking up stiff, sweaty, or still exhausted.
Neck or Shoulder Stiffness
Waking up with tightness or discomfort, even after a full night’s sleep.
Hot or Sweaty Sleep
Flipping to the “cool side” of your pillow — and still waking up warm.
One-Height Pillows Don’t Work
Changing positions at night, but your pillow stays the same.
Skin Safety Matters (Kids Included)
Preferring materials that feel gentle, breathable, and certified safe.
What You’ll Notice After Switching
- Your neck feels supported — not forced
- Mornings feel less stiff — more refreshed
- Sleep feels calm and uninterrupted
- No overheating or pressure build-up
Thoughtfully Chosen Materials
Adjustable foam cubes → height that fits your body
Instead of forcing your neck into one shape, you adjust the pillow to match how you sleep — side, back, or somewhere in between.
Gel-infused memory foam → draws heat away while you sleep
Cooling gel helps disperse trapped warmth, so your pillow feels balanced — not stuffy.
Breathable cube structure → airflow, less humidity build-up
Unlike solid foam blocks, the cube design allows air to move through the pillow — reducing heat and moisture retention.
Dual-sided cover → comfort that adapts to seasons
One side: Cooling-touch surface for warmer nights.
One side: Bamboo-blend fabric for softer, everyday comfort.
Flip depending on how your room feels.
Designed to Perform — Night After Night
Engineered for consistency, not just first-night comfort.
Maintains Loft Over Time
Unlike traditional fiber pillows that flatten, the cube structure retains its volume — with no clumping or hollow spots forming.
Consistent Neck Alignment
The adjustable cube fill distributes evenly, supporting your natural neck curve without collapsing through the night.
Balanced for Warm Climates
The open cube design and cooling fabric allow air to circulate — reducing heat and humidity build-up.
Built for heat, humidity, and everyday use.
Engineered for Singapore Living
KumoFlex isn’t designed for cold climates or showroom comfort. Its open cube structure and cooling-touch cover are made to stay breathable — even in warm, humid nights. No heavy foam. No trapped heat.
Tested for comfort, not trends.
Materials Chosen with Intention
From CertiPUR-US® foam to OEKO-TEX® tested fabric, every component is selected for skin safety, durability, and long-term performance. Because sleep products sit against your skin — every night.
One pillow. Two comfort surfaces.
Flip for Your Sleep Style
Use the cooling-touch side for warmer nights or if you sleep hot. Flip to the bamboo-blend side for softer everyday comfort. Adjust based on your room temperature — not just your sleep position.
Sleep Should Be Safe.
Materials tested for skin contact — every night.
CertiPUR-US®
Foam made without harmful chemicals. Low VOC emissions for indoor air quality.
OEKO-TEX®
Fabric tested against harmful substances. Safe for prolonged skin contact.
GRS Certified
Responsible sourcing of recycled materials. Better for you — and better for the environment.
Choose Your Size
Same adjustable comfort — tailored to your bed and sleep style.
Standard Size
Balanced support for most sleepers
Designed for single and queen beds, this size suits back, combination, and light side sleepers. Adjust the loft easily to match your preferred height — without overfilling.
King Size
Extra width. Extra freedom.
Ideal for side sleepers or those who prefer more surface area. The wider design prevents arm compression and keeps support consistent across larger beds.
