What’s the BluTech Fusion Fill (BFF) in the Parallel Pillow?

There’s nothing like snuggling up with your BFF.

In this case, I’m talking about the BluTech Fusion Fill inside the new Parallel Pillow! The BFF fill inside every Parallel Pillow is one of the most important ingredients in the unique “recipe” that makes them feel so amazing, from the inside out.

What is BluTech Fusion Fill (BFF)?

Our BFF fill is a hybrid blend made from 2 types of shredded memory foam +  downy, hypoallergenic fibers made from recycled water bottles. This unique blend has twice the airflow of conventional foam fills, it’s blue, and it uses some fantastic technology to keep you comfortable through the night, year-round.

The first thing that makes our BFF special is how comfortable pliant it feels! BFF is remarkably sculptable, meaning you can mold it to give you exactly the support you need, regardless of the position you’re sleeping in at the moment. 

Why is being "sculptable" important?

While pillows designed for side sleepers or tummy sleepers can work well if you stay in one position, most of us move around many times while we sleep. In fact, a study by the American Sleep Disorders Association and Sleep Research Society found that people change positions between 10 and 40 times in a night!

It’s easy to understand how a pillow that supportively shape-shifts with you as you move can make a huge difference in your overall sleep quality. 

It won't go flat like other pillows

The next best thing bout our BluTech Fusion Fill is that it won't go flat like other pillow fills, and this was a conscious decision. 

Instead of using blocks of memory foam like traditional memory foam pillows, we designed the Parallel Pillow to be made with shredded memory foam pieces as well as soft, synthetic fibers. Why? Well, while traditional memory foam pillows offer an incredible sense of support, they can be too dense-feeling for many people, and they're known for trapping in body heat.

We used shredded memory foam pieces instead of traditional memory foam to give Parallel Pillows the same supportive feeling as traditional memory foam, but without the downsides! Our BFF fill can be shaped in anyway you like, and it's even more breathable than non-memory foam pillows!

And here's our favorite trick: if you ever do feel like your Parallel Pillow is feeling flatter than usual, just throw it in the dryer for a few minutes! Adding heat to foam allows it to expand back to its original shape, which means your Parallel Pillow can always feel like new with just the push of a button.

 

 

BluTech Fusion Fill Specs

Want to geek out on the details? (Ah, a kindred spirit – perfect!) Here are a few interesting points about our BFF:

  • The Parallel Pillow’s BluTech Fusion Fill is 25% microfiber and 75% foam by weight.
  • The fluffy down-alternative microfiber is made of 100% recycled material, spun from the plastic of an average 20 recycled water bottles. A high-profile king Parallel Pillow upcycles 23 bottles!
  • The blue memory foam pieces are made with a high-tech gel that immediately responds and adjusts to your body movements. With double the airflow of other foam fills, it combines the resiliency of latex with the pressure-relieving conformance of memory foam. And with low temperature sensitivity, the blue memory foam keeps you at the right temperature year-round.
  • The dark memory foam is an ultra comfy foam that also has the benefit of being a USDA Certified Biobased Product, with 28% bio-based content coming from high loading of plant-based polyol.
  • Both foam components can be recycled after use to further reduce environmental impact, and both are made without ozone depleters, formaldehyde or phthalates.
  • BluTech Fusion Fill is CertiPUR-US Certified, and it's made right here in the USA.

In short, our BFF makes the Parallel Pillow temperature neutral, so it’s never too hot or too cold. It doesn’t flatten out, and provides cloud-like loft and huggable support all night long — every night.

Premium Materials

TENCEL™ Washable Outer Cover
The outer cover is ultra-soft and breathable, made from sustainable TENCEL™ Lyocell fibers that wick moisture and dissipate heat to maintain a consistent, comfortable sleep surface.
Enhanced with Move and Cool™, a plant-based moisture management treatment that improves evaporation and stays effective for up to 30 washes.

ParaPur™ Antimicrobial Inner Cover
Our 4-way stretch inner liner is permanently embedded with Ionic+™ silver ions—a mineral-based antimicrobial technology that destroys 99.99% of microbes.
Because this layer isn’t washable, we made sure it stays fresh for the life of the pillow.


Blutech Fusion Fill (BFF)
Inside is our custom blend of:

  • Down-alternative microfibers (25% by weight): soft, lofty, and made from 100% recycled material—the equivalent of up to 23 plastic bottles per pillow
  • Traditional memory foam (37.5%): plant-based polyol foam for deep, conforming support
  • Gel memory foam (37.5%): temperature-stable and quick-response for consistent support and airflow

All foams are CertiPUR-US® certified, meaning they're made without harmful chemicals and meet rigorous standards for content, emissions, and durability.
