AoYuki Flex Cube Memory Foam – Ultimate Customizable Comfort
AoYuki Flex Cube Memory Foam is made from 100% pure shredded memory foam for customizable support and cooling comfort. Suitable for DakiFlex, KumoFlex, or other brand pillows and bolsters. Breathable, durable, and hypoallergenic.
Pure Shredded Memory Foam for Personalized Support
Each bag of AoYuki Flex Cube Memory Foam is filled with premium, 100% pure shredded memory foam. This design lets you adjust the fill level of your pillows or bolsters to suit your preference. Whether you want extra loft or a softer feel, simply add or remove foam. The shredded cubes mold easily, offering excellent adaptability and ensuring your head, neck, and shoulders are always properly supported.
Unlike generic fillers that may flatten or clump, AoYuki Flex Cube Memory Foam maintains its shape. Enjoy restful sleep without constantly fluffing your pillow throughout the night. Every cube bounces back naturally, preserving structure and comfort over time.
Cooling Comfort for Restful Sleep
Struggling with hot, restless nights? AoYuki Flex Cube Memory Foam was designed to promote airflow and cooling comfort. Its open-cell structure helps air circulate, preventing heat buildup inside your pillow or bolster. This means your sleep surface stays fresh, even in humid conditions or warm weather.
The cooling properties of the memory foam allow your body to relax into a comfortable temperature zone. This dedication to cool and breathable sleep makes AoYuki Flex Cube Memory Foam a smart solution for both children and adults who experience night sweats or easily get overheated while sleeping.
Compatible with Major Pillow and Bolster Brands
Whether you use DakiFlex, KumoFlex, or another popular pillow or bolster brand, AoYuki Flex Cube Memory Foam works seamlessly. The flexible cubes ensure easy redistribution inside any pillowcase or bolster shell. It is the perfect refill solution for extending the lifespan of your favorite sleep essentials.
Switch out lumpy or compressed filler materials for pure, supportive memory foam cubes. Refresh your old pillows and bolsters instantly without the need for a full replacement. This versatile refill is suitable for a wide range of cushion types, making it an essential bedding upgrade for any household.
Breathable, Durable, and Hypoallergenic
Breathability is a key feature of AoYuki Flex Cube Memory Foam. The cubes do not trap moisture, helping your sleep environment remain hygienic and fresh. Durability is another highlight—the foam is engineered to resist crumbling or breaking down with regular use.
Hypoallergenic qualities make this product safe for sensitive sleepers, children, or individuals with allergies. The material is free from harmful chemicals, toxins, or unnecessary additives. Rest with confidence knowing you have bedding that prioritizes clean, healthy sleep for everyone in your home.
Easy to Use and Maintain
AoYuki Flex Cube Memory Foam is simple to use. Refilling your pillow or bolster is easy—open the zipper, add or remove foam until you find the perfect height, and close it up. Adjust as needed whenever your comfort preferences change.
Maintenance is hassle-free. The foam should not be washed in water. Instead, spot clean only when necessary and air out occasionally to keep it fresh. Regular fluffing prolongs loft and bounciness, maintaining comfort through years of use.

- Side Sleepers: Achieve better neck and shoulder alignment with elevated support.
- Back Sleepers: Promote natural spinal alignment for pressure relief.
- Stomach Sleepers: Reduce strain by adjusting foam for a flatter pillow.

Is AoYuki Flex Right for You?
Perfect for anyone frustrated with clumpy, hot, or flattening shredded foam.
Your Pillow Feels Lumpy & Uneven
Mixed shredded foam clumps within weeks, causing uneven pressure and poor neck alignment.
You Sleep Hot or Wake Up Sweaty
Cheap foam traps heat. Polyester fillers make it worse.
Your Pillow Height Is Never “Just Right”
Fixed-height pillows cause neck pain — too high or too flat.
Your Pillow Flattens Within Months
Cheap shredded foam breaks down quickly and loses support.
What You’ll Notice After Switching to AoYuki Flex Cube
Not just better foam — this is how your pillow finally feels balanced, breathable, and supportive again.
Clump-Free & Even Support
AoYuki Flex Cube stays uniform and supportive without forming lumps — unlike mixed shredded foam that clumps and creates pressure points.
Cooling, Breathable & Heat-Regulating
Gel-infused memory cubes increase airflow so heat escapes quickly — keeping your pillow cool even in Singapore’s warm nights.
100% Pure Memory Foam — No Fillers
Unlike cheap foam mixed with polyester scraps, AoYuki uses 100% pure certified memory foam that lasts years without flattening or irritating sensitive skin.
Engineered to stay even and supportive — no more lumpy or sagging shredded foam.
Adaptive Support That Never Clumps or Sinks
AoYuki Flex Cube Memory Foam moves with you while staying evenly distributed, eliminating the common problems of mixed shredded foam like clumping, pressure points, and mid-night sinking.
Every cube adapts independently to your head, neck, and shoulders for stable support from dusk till dawn.
Designed for Singapore’s warm, humid weather.
Cooling Gel-Infused Cubes for Sweat-Free Nights
Each cube is gel-infused and naturally creates airflow channels that let heat escape quickly.
The result? A pillow that feels fresh, breathable, and comfortable — even for hot sleepers who wake up sweaty using standard shredded foam.
Just premium foam, no polyester scraps or hidden stuffing.
100% Pure Memory Foam — No Fillers, No Shortcuts
Unlike cheap shredded pillows that mix leftover foam, polyester fillers, or fabric scraps, AoYuki uses only clean, high-density memory foam cubes.
This means better durability, safer sleep, and support that stays consistent for years — without flattening, irritating skin, or releasing odors.
